Journal ArticleDOI

Performance of electron reconstruction and selection with the CMS detector in proton-proton collisions at √s = 8 TeV

Khachatryan, +2121 more
TL;DR: In this article, the performance and strategies used in electron reconstruction and selection at CERN LHC are presented based on data corresponding to an integrated luminosity of 19.7 inverse femtobarns, collected in proton-proton collisions at sqrt(s) = 8 TeV.
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

Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV

Khachatryan, +2288 more
TL;DR: In this paper, an improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb^(-1) collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are presented.
