Top results from CMS
The top quark has a special place in the Standard Model (SM). It is the heaviest elementary particle known to date, its mass [1] being very close to the scale of electroweak symmetry breaking. As such it plays a special role in many models of new physics beyond the SM. In the SM, the top quark decays almost exclusively to a W b pair. At the LHC [2], the top quark is predominantly produced in pa...
متن کاملSoft QCD Results from CMS
Studies of hadron production in proton-proton collisions, including charged particle transverse momentum, pseudo-rapidity and event-by-event multiplicity distributions at √ s = 0.9, 2.36 and 7 TeV are shown. Measured spectra of identified strange hadrons, reconstructed based on their decay topology, are also presented. Comparisons to several QCD Monte Carlo models and tunes are discussed. Resul...
متن کاملStudy of -jet identification in CMS
We present the methods for off-line -jet identification developed for the study of decay modes of the neutral SUSY Higgses of mass 140 300 GeV in CMS. Detector response is simulated with a GEANT-based package CMSIM. Involving calorimetry and tracker information, -jet selection criteria allow to reduce the backgrounds to an acceptable level while keeping the selection efficiency at the level of ...
متن کاملJet Physics in CMS Heavy Ion Programme
In this note, we report on the study of jet+ jet, γ + jet and Z(→ μμ) + jet production in heavy ion collisions. In particular, we review the capability of the CMS detector to observe the energy losses of quarkand gluon-initiated jets in a dense QCD matter. 1 Jet quenching: jet + jet, γ + jet and Z + jet production Hard jet production is considered to be an efficient probe for formation of super...
متن کاملDirect Photon plus Jet Study for CMS
We present simulation results of γ + Jet analysis using CMS (Compact Muon Solenoid) Object-Oriented software at the LHC center of mass energy ( √ s=14 TeV). The study of direct photon production helps in validating the perturbative quantum chromodynamics (pQCD) and constraining the gluon distribution of nucleons. Direct photon processes also represent a major contribution in estimating backgrou...
