Determination of jet energy calibration and transverse momentum resolution in CMS

S. Chatrchyan, +2271 more
TL;DR: In this article, the transverse momentum balance in dijet and γ/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transversal momentum resolution.
Journal ArticleDOI

Description and performance of track and primary-vertex reconstruction with the CMS tracker

S. Chatrchyan, +2387 more
TL;DR: In this paper, a description of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices is provided.
Journal ArticleDOI

Search for neutral heavy leptons produced in Z decays

P. Abreu, +587 more
TL;DR: Weak isosinglet neutral heavy leptons (m) have been searched for using data collected by the DELPHI detector corresponding to 3:3 106 hadronic Z0 decays at LEP1.
Journal ArticleDOI

Measurement of the inclusive W and Z production cross sections in pp collisions at √s = 7 TeV with the CMS experiment

S. Chatrchyan, +2250 more
TL;DR: In this paper, a measurement of W and Z production cross sections in pp collisions at 7 TeV is presented, where electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns.
Journal ArticleDOI

Measurement of jet fragmentation in PbPb and pp collisions at root s(NN)=2.76 TeV

S. Chatrchyan, +2196 more
- 18 Aug 2014 - 
TL;DR: In this paper, a data sample of PbPb collisions collected in 2011 at a nucleon-nucleon center-of-mass energy of √sNN = 2.76 TeV corresponding to an integrated luminosity of 150μb^(−1) is used.
