89. A Framework for Interdisciplinary Research in High-Energy and Nuclear Physics

Early Career Scientist

The intersection between high-energy and nuclear physics has been growing in recent times. As an early career nuclear physicist, I am excited by the prospect of employing detector technologies and analysis techniques established in high-energy physics at future mega-nuclear physics facilities such as the electron-ion collider (EIC). Fast-time pixel or strip AC-LGAD sensors, as well as the...

24. A Liquid Argon Detector for the Far Forward Neutrinos at the LHC

The FASER experiment detected, for the first time, neutrinos from pp collisions in the LHC. These neutrinos have energies between the most energetic neutrinos ever produced by human-made sources until now and high-energy cosmic neutrinos. This discovery opens a new window for studying TeV-energy neutrinos of all three flavors, as well as BSM and QCD physics. A liquid argon detector with high...

117. A US-based future collider initiative for physics prospects and detector R&D

Early Career Scientist

The community, as emerged from the Energy Frontier report, supports the possibility of a Higgs factory and the R&D for a future muon collider in the US. Indeed, given global uncertainties, consideration should also be given to the timely realization of a possible domestic Higgs factory, in case none of the currently proposed options are realized.
In general, the investment in detector and...

88. Beyond the Energy Frontier: Advancing Precision Measurements and Exploring the Unknown

Early Career Scientist

The Energy Frontier’s Snowmass report carefully laid out the plans of the US EF community to reach the next level of precision measurements and explore beyond the current known energy scales. This plan is a guideline for what we should be aiming to achieve. It also will inspire the next generation of particle physics experimentalists and revitalize the US community. In this 5 minute talk I...

90. Broad impact of the Energy Frontier towards BSM searches in synergy with the other frontiers: Axion and ALP example

Early Career Scientist

Energy frontier searches have a broad impact on and synergy with the other frontiers. In this talk, I will focus on how terrestrial probes, especially the energy frontier experiments, can play an important role in this regard, in combination with cosmic and intensity frontier probes. I will give an example involving heavy axions that solve the strong CP and axion quality problem, and how the...

15. Brookhaven HEP Program, Short Remarks Session

107. Can future colliders be the light to see dark matter?

Early Career Scientist

Despite different astrophysical measurements indicate the existence of dark matter, no evidence for its non-gravitational interactions with standard model particles is yet available. If these interactions are present, dark matter could be produced at colliders, and many searches are performed in this direction at LHC. A very interesting opportunity to further shed light on the dark matter...

11. Closed Session

31. DarkQuest: A dark sector upgrade to SpinQuest at the 120 GeV Fermilab Main Injector

Early Career Scientist

Expanding the mass range and diversifying the techniques used in the search for dark matter is an important part of the worldwide particle physics program. Accelerator-based searches for dark matter and dark sector particles are a uniquely compelling part of this program as a way to both create and detect dark matter in the laboratory and to explore the dark sector by searching for mediators...

27. Data Preservation in High Energy Physics

Data Preservation (DP) is a mandatory specification for any present and future experimental facility and it is a cost-effective way of doing fundamental research by exploiting unique data sets in the light of the ever increasing theoretical understanding. When properly taken into account, DP leads to a significant increase in the scientific output (10% typically) for a minimal investment...

115. Detector R&D for future colliders

Not Early Career Scientist

Detector R&D for future colliders requires large collaborative efforts, years of development, and shared resources are key for successful outcomes. I would like to provide remarks on the needs for the community to develop and maintain a common framework for detector R&D for future experiments, in concert with accelerator R&D such that they can be develop together and support each other. Such...

119. Dual readout crystal calorimetry for precision measurements at future colliders

Early Career Scientist

While adequately supporting the construction, operation, and physics mission of the High Luminosity LHC (HL-LHC) begins to build the foundation for the HEP calorimetric techniques of the future, increased investment in calorimetry R&D is needed to meet the demands of future colliders. The calorimeters of the collider experiments beyond the HL-LHC, for both lepton machines and future hadron...

100. Elucidating the quark and gluon distributions in the nucleon, pion, and kaon from lattice QCD

Early Career Scientist

Understanding the internal structure and dynamics of protons and neutrons - the complex many-body systems consisting of strongly interacting quarks and gluons - is at the core of exploring the visible matter universe. However, precise knowledge of the gluon distributions and their roles in hadron structures remains one of the most challenging but fundamental issues in nuclear and particle...

114. Large Language Models for Particle Physics Experiments

Early Career Scientist

Particle Physics experiments rely on large code bases. These include proprietary code for common programming languages, as well as code and instructions for specialized programs and languages. Working with these, as well as developing, maintaining, and creating such code is part of the work of particle physicists.
AI driven Large Language Models like Chat GPT-4 have recently made great leaps...

86. Long-term development of 4/5D detectors for future colliders and blue-sky R&D

Early Career Scientist

In the past few years, the Low Gain Avalanche Detector (LGAD, thin silicon detectors with modest internal gain and extremely good time resolution) technology have been significantly advanced. The first application of this kind of device will be in the ATLAS and CMS timing layers at the HL-LHC. The first prototypes of LGADs produced few years ago within the collaborations did not show...

112. Maximizing the Return on US Investment in the LHC: Time to Take Action

Early Career Scientist

Despite investing a massive $500,000,000 in the construction of the
Large Hadron Collider (LHC) and committing a significant portion of our
high-energy experimental community to the LHC, there is a risk that we
may struggle to comprehend the results due to the limitations of our
current precision theory modeling. This is particularly concerning given
the LHC's future role as a precision...

109. milliQan and future ancillary experiments

Early Career Scientist

During LHC Run3, the milliQan experiment will search for millicharged particles as an indicator of a dark sector, expecting to exclude much of the previously unexplored parameter space in the 1GeV to 100GeV mass range. Besides the advantage of exploring a large phase space at relatively low cost, small ancillary experiments like milliQan are very student friendly: there are many opportunities...

Not Early Career Scientist

Abstract

The talk offers a perspective on the most widely used HEP simulation tool, i.e., Geant4, and related challenges faced by US HEP community and Geant4 Collaboration, especially the ones related to the Geant4 physics models and the lack of personnel.
It centers on a quote from [(the Snowmass2021 Book)][1] Rare Processes and Precision Measurements Frontier (RPF) p538-539:
• The RPF...

121. On-chip intelligence and real-time data-processing

Early Career Scientist

Highly granular pixel detectors allow for increasingly precise measurements of charged particle tracks, both in space and time. A reduction in pixel size by a factor of four in next-generation detectors will lead to unprecedented data rates, exceeding those foreseen at the High Luminosity Large Hadron Collider. Despite this increase in data volume, smart data reduction within the pixelated...

75. Physics On the way to 10 TeV

Early Career Scientist

An immediate result of Snowmass 2021 is the community’s clear intention to reach the multi-TeV scale with colliders, in particular with large support behind a 10 TeV muon collider. While the timescale to 10 TeV center-of-mass collisions is most quickly realized with a muon collider, the projection for construction is still upwards of 25+ years. In this remark, I will illustrate physics...

20. Precision theory for energy and intensity frontiers

Precision theoretical calculations have guided experimental discoveries, such as the Higgs boson, top quark, and neutrino masses. They are essential for distinguishing signals of New Physics from the Standard Model background, designing new experiments, and providing insight into the fundamental nature of the universe. Investing in theoretical support for experiments is critical for the future...

123. Shifting trends in the research involvement of a younger and more global generation of scientists

Early Career Scientist

Our high energy physics community is experiencing a transition period, and a different set of challenges in manpower than those from a couple decades ago. In terms of research participation, I find from discussions among young experimental researchers in my community that there is increasing willingness to get involved in multiple frontiers and for them to utilize their expertise in broader...

29. Strong and Robust Searches for Millicharged Particles at the Energy Frontier with LHC FPF and FORMOSA

We identify potentially the world's most sensitive location to search for millicharged particles in the 10 MeV to 100 GeV mass range: the forward region at the LHC. In this location, we propose constructing a scintillator-based experiment, FORward MicrOcharge SeArch (FORMOSA) [1], and estimate the corresponding sensitivity projection. We show that FORMOSA can discover millicharged particles in...

83. The importance of shielded transverse detectors for BSM physics with long-lived particles

Early Career Scientist

The observation of the decay in flight of exotic long-lived particles with $c \tau >\mathcal{O}(1~\mathrm{m})$ would be a compelling signature for many Beyond Standard Model (BSM) scenarios. The sensitivity to such particles of existing LHC experiments, however, is limited by complicated trigger environments, high backgrounds, and/or geometric restrictions to the forward region, leaving a...
