Study of Hadronic Event-Shape Variables
(2009)CMS Physics Analysis SummariesIn this note a study of hadronic event shapes in QCD events at the Large Hadron Collider (LHC) is presented. Calorimetric jet momenta, determined by various jet clustering algorithms, are used as input for calculating various event-shape variables which probe the structure of the hadronic final state. It is shown that the normalized event-shape distributions are robust under variations of the jet energy scale and resolution effects, which ...Report -
Plans for Jet Energy Corrections at CMS
(2008)CMS Physics Analysis SummariesJet corrections at CMS will initially be derived from simulation tuned on test beam data, determined directly from collision data when available, and ultimately from a simulation tuned on collision data. The corrections will be factorized into a fixed sequence of sub-corrections associated with different detector and physics effects. The following three factors are minimum requirements for most analysis: offset corrections for pile-up and ...Report -

Search strategy for the Higgs boson in the ZZ* decay channel with the CMS experiment
(2010)CMS Physics Analysis SummariesA study of the sensitivity for the inclusive production of Standard Model Higgs bosons H decaying in ZZ() pairs is presented with the CMS experiment at the CERN LHC pp collider at 14 TeV centre of mass energy, for the integrated luminosity of 1 fb−1. The analysis is performed for the leptonic decay channels HZZ()4 with =e and for a mass mH in the range from 120 to 250 \GeVcc. % Signal and background datasets obtained with a detailed Monte ...Report -
Performance of the kt jet algorithm in CMSSW
(2007)CMS Internal NoteFirst studies of the performance of the kt jet algorithm and its implementation in CMSSW are summarized. Jet efficiency, response and resolutions in QCD events and the performance of the algorithm in the selection and reconstruction of hadronic decays of weak bosons are presented. The new pile-up and underlying event subtraction method provided in the FastJet package has been tested and first results are also shown.Report -
