Reevaluation of the parton distribution of strange quarks in the nucleon
The HERMES Collaboration, A. Airapetian, N. Akopov +111
An earlier extraction from the HERMES experiment of the polarization-averaged parton distribution of strange quarks in the nucleon has been reevaluated using final data on the mult…
Performance of the first prototype of the CALICE scintillator strip electromagnetic calorimeter
CALICE Collaboration, K. Francis, J. Repond +191
A first prototype of a scintillator strip-based electromagnetic calorimeter was built, consisting of 26 layers of tungsten absorber plates interleaved with planes of 45x10x3 mm3 pl…
Shower development of particles with momenta from 1 to 10 GeV in the CALICE Scintillator-Tungsten HCAL
C. Adloff, J. -J. Blaising, M. Chefdeville +215
Lepton colliders are considered as options to complement and to extend the physics programme at the Large Hadron Collider. The Compact Linear Collider (CLIC) is an collide…
Transverse target single-spin asymmetry in inclusive electroproduction of charged pions and kaons
The HERMES Collaboration, A. Airapetian, N. Akopov +129
Single-spin asymmetries were investigated in inclusive electroproduction of charged pions and kaons from transversely polarized protons at the HERMES experiment. The asymmetries we…
Potential Impact of a New GEM-based Detector on CMS Triggering
A. Castaneda
With the increases in the LHC instantaneous luminosity, maintaining effective triggering and avoiding dead time will become especially challenging. As the sensitivity of many physi…
Beam-helicity asymmetry in associated electroproduction of real photons in the -resonance region
The HERMES Collaboration, A. Airapetian, N. Akopov +114
The beam-helicity asymmetry in associated electroproduction of real photons, , in the (1232)-resonance region is measured using the longitudinally polarized HERA pos…
Scalar Dark Matter Models with Significant Internal Bremsstrahlung
Federica Giacchino, Laura Lopez-Honorez, Michel H. G. Tytgat
There has been interest recently on particle physics models that may give rise to sharp gamma ray spectral features from dark matter annihilation. Because dark matter is supposed t…
Track segments in hadronic showers in a highly granular scintillator-steel hadron calorimeter
CALICE Collaboration, C. Adloff, J. -J. Blaising +205
We investigate the three dimensional substructure of hadronic showers in the CALICE scintillator-steel hadronic calorimeter. The high granularity of the detector is used to find tr…
Search for supersymmetry in hadronic final states with missing transverse energy using the variables AlphaT and b-quark multiplicity in pp collisions at 8 TeV
CMS Collaboration
An inclusive search for supersymmetric processes that produce final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of 8 TeV…
The HERMES Recoil Detector
A. Airapetian, E. C. Aschenauer, S. Belostotski +80
For the final running period of HERA, a recoil detector was installed at the HERMES experiment to improve measurements of hard exclusive processes in charged-lepton nucleon scatter…
Simulation of the CMS Resistive Plate Chambers
R. Hadjiiska, L. Litov, B. Pavlov +61
The Resistive Plate Chamber (RPC) muon subsystem contributes significantly to the formation of the trigger decision and reconstruction of the muon trajectory parameters. Simulation…
Inclusive search for supersymmetry using the razor variables in pp collisions at sqrt(s) = 7 TeV
CMS Collaboration
An inclusive search is presented for new heavy particle pairs produced in sqrt(s) = 7 TeV proton-proton collisions at the LHC using 4.7 +/- 0.1 inverse femtobarns of integrated lum…
