Channeling radiation is an appealing radiation process to produce X-ray radiation with low energy electron beams. We plan to use our novel photo and field emission cathodes to generate very small emittance electron beams to make channeling radiation X-ray sources. In this contribution we discuss the anticipated performance and construction status of a channeling radiation experiment to produce...

The CMS pixel detector is a tracking device located closest to the interaction point. The present detector was designed for a maximum luminosity of 1×10^34 cm^−2s^−1. Following the Phase 1 upgrade of the LHC, the peak luminosity is foreseen to reach 2×10^34 cm^−2s^−1 or higher. Due to the radiation damage and significant data losses in the readout chip, the present pixel system must be...

The CMS pixel detector is an all-silicon tracking device located
closest to the interaction point. Following the first long shut down
of the LHC, in order to maintain the high performance of the tracker,
the pixel detectors must be upgraded to handle the increased amounts
of event pileup. One of the components of the upgrade is the forward
pixel detector, which uses a High Density...

At the core of the CMS all-silicon tracking system is the silicon pixel detector, comprising three barrel layers and two pixel disks in the forward and backward regions, accounting for a total of 66 million channels. The pixel detector provides high-resolution 3D coordinates of the tracks produced in high energy pp collisions. Under the combined action of electric and magnetic fields, the...

A search for heavy resonances decaying into $\tau^{+}\tau^{-}$ is performed using 4.94 fb$^{-1}$ of proton-proton collision data at 7 TeV recorded by the CMS detector during LHC Run2011. The estimation of major backgrounds is performed using data-driven methods wherever possible. A cut and count approach is followed to look for excess of observed events over the Standard Model background...

One of the most important decay channels of the standard model Higgs is its decay into a pair of bottom quarks. For the highest signal significance, the associated production of the Higgs with a W or Z boson is investigated. Six different channels are used: $W(\mu\nu)H, W(e\nu)H, W(\tau\nu)H, Z(\mu\mu)H, Z(ee)H$ and Z(\nu\nu)H$. A data sample, recorded by the CMS detector at the LHC,...

We present the search for W' -> tb using the LHC pp collision data collected with the ATLAS detector at a center-of- mass energy of 8 TeV. The primary backgrounds to this search are ttbar, W+jets, and multijets processes. To reduce the contributions of these backgrounds we require a leptonic final state and use Boosted Decision Trees to discriminate against background-like events. This...

Associated production of a Z boson with a charm or bottom quark
can serve as an important test of perturbative quantum chromodynamic
calculations. The ratios of cross sections,
\sigma(Z+c-jet)/\sigma(Z+jet) and \sigma(Z+c-jet)/\sigma(Z+b-jet)
are measured for associated production of a Z boson with jets
as a function of the jet and Z boson transverse momentum.
Measurements use data...

The parity and time-reversal invariant effective Lagrangian
for a heavy fermion interacting with an Abelian gauge field, i.e.,
NRQED, is constructed through order $1/M^4$. The implementation of
Lorentz invariance in the effective theory becomes nontrivial at this order,
and a complete solution for Wilson coefficient constraints is obtained. Matching
conditions in the one-fermion...

The standard model of particle physics has been remarkably successful in accounting for every experimental result to date, with the exception of the acceleration of the universe. However, this theory becomes inconsistent at intervals shorter than the Planck scale, where quantum mechanics and general relativity collide, unless the geometry of space-time itself also acquires some quantum...

In order to study a sample of galaxy clusters exhibiting strong gravitational lensing, we took images of ten galaxy clusters at Kitt Peak National Observatory. In our analysis, we extrapolated the total number of galaxies in the outer regions of the clusters because some sections of the clusters were outside of our original images. In early 2012, we took new observations of some of these...

I will discuss the new Silicon results from the CDMS experiment. I will primarily talk about the observed events and their statistical significance as light WIMP candidates. In the paradigm of light WIMPs we will see how the SuperCDMS experiment intends to search for light WIMP dark matter using the CDMSlite experiment.

"The observation of neutrino oscillation provided the first evidence for physics beyond the standard model. MINOS has been one of the foremost experiments in the field. Pioneering the two-detector technique, the MINOS long-baseline oscillation experiment has made several world-class neutrino oscillation measurements, not only making the most precise measure of the largest neutrino mass...

The Neutrinos at the Main Injector (NuMI) delivers an intense muon neutrino beam in an energy range of 2-20 GeV. A well known neutrino flux is crucial to make absolute cross sections in experiments like Minerva. Several techniques are currently using to constraint the flux and one of then is to use the existing external hadron production data to reduce the NuMI hadron production uncertainties...
