In this talk LUXE (Laser Und XFEL Experiment) is discussed. It is an experiment that aims to use the high-quality and high-energy electron beam of the European XFEL and a powerful laser. The scientific objective of the experiment is to study quantum electrodynamics processes in the regime of strong fields. High-energy electrons, accelerated by the European XFEL linear accelerator, and...
The LHeC and the FCC-eh are the cleanest, high resolution microscopes that the world can build in the nearer future. Through a combination of neutral and charged currents and heavy quark tagging, they will unfold the parton structure of the proton with full flavour decomposition and unprecedented precision. In this talk we will present the most recent studies on the determination of proton...
SoLID spectrometer was proposed to fully exploit the potential of JLab 12 GeV energy upgrade. It is a large acceptance detector which can handle very high luminosity. An overview of the exciting rich physics program will be given, which includes a number of planned measurements: a multi-dimensional mapping of semi-inclusive DIS asymmetries to reach ultimate precision for tomography of the...
The LHCb detector is currently being upgraded to be able to take data at higher luminosities and with greater efficiency in Run3. This involves replacement of many subdetector systems, including the vertex detector, upstream tracker, the photodetectors of the ring-imaging Cherenkov detectors, and the downstream tracker. Equally important will be a complete redesign of the data-acquisition...
The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at the unprecedented center of mass energy of 13 TeV. For the next period of data taking (Run 3), the LHC is expected to deliver an additional 300/fb with pile-up conditions similar or exceeding those of Run 2. A high-luminosity upgrade of the LHC - the High-Luminosity LHC (HL-LHC) - is planned...
The LHeC provides a comprehensive physics programme with strong implications on that of the HL-LHC. We will present a chapter of the 2020 LHeC White Paper, that is firstly the implications of the precise determination of proton PDFs at the LHeC on the measurement of key SM parameters at the HL-LHC: EW mixing angle, W mass and their impact on EW precision measurements. Then we will address the...
We present a quantitative assessment of the impact the future Electron-Ion Collider would have in the determination of parton distribution functions in the proton and parton-to-hadron fragmentation functions through semi-inclusive deep-inelastic electron-proton scattering data.
Specifically, we estimate the kinematic regions for which the forthcoming data are expected to have the most...
The LHeC and the FCC-eh will extend the kinematic region presently available in DIS to very small values of $x$ in the perturbative $Q^2$ region. Therefore, they will be able to establish the dynamics of the strong interaction at small $x$ or high energies, and unravel the existence of a new non-linear regime of QCD where parton densities are expected to saturate. In this talk we will review...
We asses the impact of the future Electron-Ion Collider
on the collinear gluon helicity distribution ($\Delta g$).
In particular, we study the constraining power of longitudinally
polarized inclusive deep-inelastic scattering on $\Delta g$
using the $Q^2$ range covered by the EIC kinematics.
The CLAS12 detector at Jefferson Lab just started to collect data. Making use of the CEBAF high energy (up to 11 GeV) and highly longitudinal polartized (up to 90%) electron beam will cover unexplored territories in electron-scattering physics. Exclusive reactions on nuclons and nuclei will be measured with high precision in high luminosity (up to 10e35 cm-2s-1) experiments. Mapping out a...
We present NLO QCD predictions for dijet photoproduction on heavy nuclei for three future collider options at CERN, the LHeC, its high-energy (HE) version and the electron-hadron/nucleus version of the FCC, and compare them to our previous predictions for the EIC. We focus on the potential of these colliders to constrain nuclear parton densities, in particular in the small-x region, based on...
The proposed high luminosity high energy Electron Ion Collider (EIC) will explore the proton/nuclear structure, search for gluon saturation and precisely determine the nuclear parton distribution functions (nPDFs) in a wide x-$Q^{2}$ phase space. Heavy flavor and jet measurements at the future EIC will allow us to better constrain the nPDFs within the poorly constrained high Bjorken-x region,...
The LHeC and the FCC-eh, with its large kinematic reach and luminosity, offer the possibility to study hitherto uncovered, novel properties of QCD. In this talk we will review recent studies as presented in the LHeC 2020 White paper. Among other phenomena, we will discuss topics such as intrinsic heavy flavour, the determination of the running coupling at low scales, the radiation zero...
Recently, there has been increasing recognition that jet measurements can be an important component of the physics program at the future Electron-Ion Collider (EIC). Jets are a more effective proxy for partonic kinematics than the single hadron measurements usually performed in Deep Inelastic Scattering experiments, while substructure techniques can be used to examine non-perturbative effects...
The Election-Ion Collider (EIC) is a next generation accelerator, which is designed to answer longstanding questions in nuclear physics. The EIC with its wide range of center of mass energies from 20 to 140 GeV, polarized beams, and beam species, as well as high luminosity, is designed to precisely image the quarks and gluons and their interactions, and to explore the new QCD frontier of...
A technique has been recently proposed to address the main limitations of past neutrino scattering experiments. In particular, it allows precise measurements of high statistics samples of (anti)neutrino-hydrogen interactions and of various nuclear targets. The planned high intensity LBNF beams give access to a broad mixture of measurements of electroweak parameters, QCD and hadron structure of...
The LHeC and the FCC-eh will open a new realm in our understanding of nuclear structure and the dynamics in processes involving nuclei, in an unexplored kinematic domain. In this talk we will review the most recent studies as shown in the update of the 2012 CDR recently delivered. We will discuss the determination of nuclear parton densities in the framework of global fits and for a single...
The LHeC and the FCC-eh offer fascinating, unique possibilities for discovering BSM physics in DIS, both due to their large centre-of-mass energies and high luminosities. In this talk we will review most recent studies as presented in the 2020 LHeC White Paper. We will show the prospects for observing extensions of the Higgs sectors both with charged and neutral scalars, anomalous Higgs...
We present the use of machine learning to reconstruct deep inelastic scattering (DIS) kinematics. In particular, we trained deep neural networks to reconstruct $x$ and $Q^2$ based on information from the lepton and the hadronic system in $e^{\pm}p$ scattering at the ZEUS experiment at HERA. These models were trained by a careful selection of Monte Carlo events. The results from the neural...
Investigating the three-dimensional structure of the nucleon has been an active field of research, especially so since the introduction of the generalized parton distributions (GPD). Research focused on this three-dimensional structure continues to be central to the hadron physics program at facilities like Jefferson Lab. The GPD formalism provides a unified description of many important...
The muonic-deuterium spectroscopic measurements obtained a significantly smaller (5.6 $\sigma$) deuterium charge radius as compared to the CODATA 2014 value. It is also 2.6 $\sigma$ away from the combined value of the proton charge radius from the muonic-hydrogen measurements and the isotope shift value from ordinary hydrogen and deuterium measurements, indicating an effect from the neutron...
Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei. As a future high energy nuclear physics project, an Electron-ion collider in China (EicC) has been proposed. It will be constructed based on an upgraded heavy-ion accelerator, High Intensity heavy-ion Accelerator Facility (HIAF) which is currently under...
The internal structure of the Nucleon has been studied for more than 60 years providing a very good understanding of its dynamics. On the other hand, the internal structure of the pion, which is in principle the simplest QCD bound state, is less explored, and its Parton distribution functions less known. Nevertheless, the presence of a virtual meson-cloud surrounding the Nucleon has been...
The talk will focus on physics goals with Run-III data and the status of ongoing and planned detector upgrades. A brief view on software upgrades and an outlook towards HL-LHC wiil also be presented.
Photoproduction at an electron-ion collider can be used to study many topics. Vector-meson photoproduction via photon-Pomeron interactions are a well-established method to study the gluon structure of nuclei. Reactions involving Reggeon exchange on proton targets can be used to study a wide variety of final state mesons, including charged mesons like the a_2^+ and Z_C^+ exotic; the...
The LHeC and the FCC-eh, offer unique prospects for the measurement of EW parameters and top properties in energy frontier, luminous ep scattering. In this talk we will revisit the determination of $Z$, $W$ and top mass through inclusive measurements. Next, we will show the possibilities for the determination of the vector and axial couplings of light quarks, of the effective weak mixing angle...
Understanding the structure and dynamics of hadron structure entails the question how the roughly 1-GeV mass scale that characterizes the proton and atomic nuclei appears, and in stark contrast why are composite Goldstone bosons such as pions and kaons abnormally light in comparison. To understand this a strong interplay between experiment and theory is crucial. The talk will present the...
Pairing of nucleons at short-range is a universal phenomenon in nuclei, and has far-reaching implications outside of understanding traditional nuclear structure. Short-range correlations (SRCs) have been extensively studied over the past few years, using facilities around the world. Although this remarkable progress has brought deep, new insight into the nature of SRCs, there are still many...
The dynamics among nucleons at short distances and the role QCD plays in it, is an outstanding problem in nuclear physics. It's understanding is important for uncovering the underlying physics of Short-Range Correlations (SRCs). In recent years, SRCs have been observed from light to heavy nuclei using fixed target experiments at Jefferson Lab via high energy electron-nucleus scattering. In...
The STAR Collaboration designs, constructs, and installs a suite of new detectors in the forward rapidity region (2.5 < eta < 4) over the next two years, enabling a program of novel measurements in pp, pA, and AA collisions. This extension of STAR’s kinematic reach will allow detailed studies of cold QCD physics at both very high and very low partonic momentum fraction, i.e. when the...
The design of the future electron-ion collider EIC at Brookhaven National
Laboratory has been continuously evolving towards a realistic, low-risk design
that meets all the requirements set forth by the nuclear physics community in
the White Paper. Over the past year activities have been focused on maturing the
design, and on developing alternatives to mitigate risk. These...
We present an overview of the Interaction Region (IR) design for the Electron Ion Collider (EIC), which will be located at Brookhaven National Laboratory (BNL). The IR is designed to meet the requirements of the nuclear physics community as outlined in [1].
The IR design features a +/-4.5 m free space for the detector; a forward spectrometer magnet is used for the detection of hadrons...
Measurements at the EIC have stringent requirements on high luminosity and acceptance of the collision final state particles, particularly in the directions along the beamline or, equivalently, extremely high rapidity. Accessing the EIC physics of interest requires unprecedented integration of the interaction region and detector designs. In this presentation, we review current detector...
The realisation of the LHeC and the FCC-eh at CERN require the development of the energy recovering technique in multipass mode and for large currents ${\cal O}(10)$ mA in the SRF cavities. For this purpose, a technology development facility, PERLE, is under design to be built at ICLab Orsay, which has the key LHeC ERL parameters, in terms of configuration, source, current, frequency and...
The Electron-Ion Collider will be the first collider to use both polarized electron beams and polarized proton and light ion beams. This will offer unique opportunities to study the structure of protons and nuclei and to answer fundamental questions in QCD.
The uncertainties on the polarization measurement translate directly into the uncertainties of final physics observables. Hence, a...
Higgs production cross sections at LHeC (FCC-eh) energies are as large (larger than) those at future Z-H $e^+e^-$ colliders. This provides alternative and complementary ways to obtain very precise measurements of the Higgs couplings, primarily from luminous, charged current DIS. Recent results for LHeC and FCC-eh are shown and their combination is presented with pp (HL-LHC) cross sections...
The sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will enable a spectrum of new or improved cold QCD measurements. With its excellent tracking and full calorimetry (hadronic and electromagnetic) in the central pseudo-rapidity region, sPHENIX provides excellent opportunities for the studies of the partonic structure and dynamics in nucleons and nuclei. This includes the...
The scattering and neutrino detector (SND) at the LHC will measure for the first time neutrino properties from $pp\rightarrow \nu X$ and search for Dark Matter in an unexplored energy and pseudo-rapidity range. It will be located in the TI18 tunnel, which is ideal due to the low environmental and machine-induced background. The detector will measure the neutrino energy and identify all three...
Tau neutrino properties are not well known in comparison to those of muon or electron neutrinos. The tau neutrino interaction cross-section is known with large uncertainties. In particular, measured by the DONuT experiment in 2008, it has about 30% statistical error and systematical error of about 50% due to a poor knowledge of the tau neutrino flux in this beam dump experiment. Precise...
In the context of the Physics Beyond Colliders initiative at CERN, the COMPASS++/AMBER proto-collaboration recently submitted a proposal to the SPSC in which a broad experimental programme of measurements at the M2 beam line of the CERN SPS is described. It addresses fundamental issues leading to significant improvements in our understanding of strong interactions in the medium and long-term...
The sPHENIX detector currently under construction at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) is designed to significantly advance studies of the microscopic nature of the Quark
Gluon Plasma. With a multi-year physics program beginning in 2023, sPHENIX employs state-of-the-art detector technologies and will fully exploit the highest planned RHIC luminosities. ...
