The High Luminosity LHC accelerator upgrade will provide five times higher instantaneous luminosity than the current LHC. This boost in luminosity will allow the Compact Muon Solenoid (CMS) experiment to probe the properties of the newly discovered Higgs boson and extend the search for new physics beyond the Standard Model. In order to handle the increased data rate and maintain high trigger...

The NOvA experiment has an 810 km long baseline and uses the upgraded NuMI neutrino beam from Fermi National Accelerator Laboratory to study neutrino oscillation parameters. The two fully active, functionally identical detectors are placed 14 milliradians off axis to access a narrow neutrino energy spectrum, due to the pion decay kinematics. The 300 ton near detector, located at Fermilab, is...

Cloud computing offers the opportunity for small research groups with fluctuating computing needs to access significant computing power with minimal investment in hardware and administration. However the cloud environment presents its own challenges, in particular those posed by the movement and storage of the large datasets used in HEP. We have evaluated two academic Infrastructure as a...

The LHCb High Level Trigger uses two stages of software running on an Event Filter Farm (EFF) to select events for offline reconstruction and analysis. The first stage (Hlt1) processes approximately 1 MHz of events accepted by a hardware trigger. In 2012, the second stage (Hlt2) wrote 5 kHz to permanent storage for later processing. Following the LHC's Long Stop 1 (anticipated end date...

MINERvA is a few-GeV neutrino scattering experiment that has been taking data in the NuMI beam line at Fermilab since November 2009. The experiment will provide important inputs, both in support of neutrino oscillation searches and as a pure weak probe of the nuclear medium. For this, MINERvA employs a fine-grained detector, with an eight ton active target region composed of plastic...

Motivated by null LHC searches for R-parity conserving SUSY, I will present the general structure of RPV couplings in presence of a Froggatt-Nielsen horizontal symmetry. For sub-TeV SUSY, lepton number must be an accidental symmetry, while baryonic RPV allows natural low-energy SUSY. The upper limit for the magnitude of the largest RPV coupling is 10^{-3} (from dinucleon decay) while the...

The Main Injector Particle Production (MIPP) experiment at Fermilab is a fixed target hadron production experiment. It measures particle production in interactions of 120 GeV/c primary protons from the Main Injector and secondary beams of $\pi^{\pm}, \rm{K}^{\pm}$, p and $\bar{\rm{p}}$ from 5 to 90 GeV/c on nuclear targets which include H, Be, C, Bi and U, and a dedicated run with the NuMI...

Following the increases in the LHC instantaneous luminosity, maintaining effective triggering and avoiding dead time will become especially challenging. As the sensitivity of many physics studies, including higgs measurements, depends critically on the ability to maintain relatively low muon momentum thresholds, the identification of potential improvements in triggering is particularly...

The LHCb experiment at CERN has proposed an upgrade towards a full 40 MHz readout system in order to run between five and ten times its initial design luminosity with an upgraded LHCb detector. As a consequence, the various LHCb sub-systems in the readout architecture will be upgraded to cope with higher sub-detector occupancies, higher rate, and higher readout load. The new architecture, new...

A search for the standard model Higgs boson in pp collisions is presented in the associated production channel Z(tautau)H(bb) where each tau decays leptonically, one to an electron, the other to a muon. A data sample comprising of 5.0 fb-1 at center-of-mass energy 7 TeV and 19 fb-1 at center-of-mass energy 8 TeV collected by the CMS detector at the LHC has been analyzed and 95% confidence...

The Daya Bay Reactor Neutrino Experiment was designed to achieve a sensitivity on the value of $\sin^22\theta_{13}$ to better than 0.01 at 90\%~C.L. The experiment consists of eight antineutrino detectors installed underground at different baselines from six nuclear reactors. With data collected from six antineutrino detectors for 140 days, Daya Bay has thus far published a measurement of...

The neutrino mixing angle $\theta_{13}$ is the gateway for studying CP violation in the lepton sector and determines the trend of future neutrino experiments. The Daya Bay Reactor Neutrino Experiment is designed to measure $\sin^22\theta_{13}$ to better than 0.01 at 90\%~C.L. This will be the most precise measurement of $\theta_{13}$ for the foreseeable future. In addition, the configuration...

When the LHC reaches beyond its current design luminosity, the load on the Level-2 trigger system will increase significantly due to both the need for more sophisticated
algorithms to suppress backgrounds and the larger event sizes. The Fast TracKer

accepted rate of 100 KHz and provide high quality tracks at the...

The Heavy Photon Search (HPS) is a new experiment at Jefferson Lab which will search for heavy $U(1)$ vector bosons (heavy/dark photons) in the mass range of 20 MeV/$c^2$ to 1 GeV/$c^2$. Dark photons in this mass range are theoretically favorable and may mediate dark matter interactions. The dark photon couples to electric charge through kinetic mixing with the photon, allowing its production...

We propose to develop a fast, thin silicon sensor with gain capable to concurrently measure with high precision the space
(~10 μm) and time (~10 ps) coordinates of a particle.
An integral part of the proposed sensors is the internal charge multiplication in silicon sensors, allowing to
thin pixelated silicon sensors by at least a factor 10 and keeping the performance of thick sensors.

Recent interest in a photon-photon collider as a possible Higgs factory has revived the question of what other physics that can be done with such machines. We demonstrate that the bb bar cross section, a large background to Higgs production at high energy photon colliders, has an uncertainty due to the resolved structure of the photon of nearly an order-of-magnitude. Hence, study of the...
