Rebalance and Smear for Multi-jet Background Estimation
Samuel Bein, Christian Sander
For many particle collider searches for physics beyond the Standard Model in final states with jets and missing transverse momentum, events from QCD multi-jet processes are an impo…
Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at sqrt(s[NN]) = 2.76 TeV
CMS Collaboration
Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (pt) w…
Measurement of the mass of the top quark in decays with a J/psi meson in pp collisions at 8 TeV
CMS Collaboration
A first measurement of the top quark mass using the decay channel t to (W to l nu) (b to J/psi + X to mu+ mu- + X) is presented. The analysis uses events selected from the proton-p…
The Status of Supersymmetry after the LHC Run 1
Philip Bechtle, Tilman Plehn, Christian Sander
Supersymmetry (SUSY) is a complete and renormalisable candidate for an extension of the Standard Model. At an energy scale not too far above the electroweak scale it would solve th…
Measurements of the ZZ production cross sections in the 2 l 2 nu channel in proton-proton collisions at sqrt(s) = 7 and 8 TeV and combined constraints on triple gauge couplings
CMS Collaboration
Measurements of the ZZ production cross sections in proton-proton collisions at center-of-mass energies of 7 and 8 TeV are presented. Candidate events for the leptonic decay mode Z…
Study of Z production in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV in the dimuon and dielectron decay channels
CMS Collaboration
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV, using data collected by the CMS experiment at…
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…
Determination of supersymmetric masses using kinematic fits at the LHC
Christian Autermann, Benedikt Mura, Christian Sander +2
In case of the discovery of supersymmetry at the LHC, the goal will be to identify the underlying theory, its fundamental parameters, and the masses of SUSY particles. We followed…
Diamond thin Film Detectors for Beam Monitoring Devices
J. Bol, S. Mueller, E. Berderman +6
Diamonds offer radiation hard sensors, which can be used directly in primary beams. Here we report on the use of a polycrystalline CVD diamond strip sensor as beam monitor of heavy…
Radiation hardness of diamond and silicon sensors compared
Wim de Boer, Johannes Bol, Alexander Furgeri +5
The radiation hardness of silicon charged particle sensors is compared with single crystal and polycrystalline diamond sensors, both experimentally and theoretically. It is shown t…
Indirect Evidence for Neutralinos as Dark Matter
W. de Boer, M. Herold, C. Sander +1
From the relic density measurement by WMAP the WIMP annihilation cross section can be determined in a model independent way. If the WIMPS are postulated to be the neutralinos of Su…
Indirect Evidence for the Supersymmetric Nature of Dark Matter from the Combined Data on Galactic Positrons, Antiprotons and Gamma Rays
W. de Boer, M. Herold, C. Sander +1
Two new observations have strengthened the case for the supersymmetric nature of the Cold Dark Matter component in our universe: First, it was shown that new data on the nuclear ab…
Positron Fraction in the CMSSM
Wim de Boer, Markus Horn, Christian Sander +1
A fit to the present data on the cosmic ray positron fraction can be considerably improved,if in addition to the positron production by nuclear interactions in the universe the pos…
