Jet charge is an estimator of the electric charge of a quark, antiquark, or gluon initiating a jet. It is based on the momentum-weighted sum of the electric charges of the jet constituents. Measurements of three charge observables of the leading jet in transverse momentum pT are performed with dijet events. The analysis is carried out with data collected by the CMS experiment at the CERN LHC in proton-proton collisions at √s = 8TeV corresponding to an integrated luminosity of 19.7 fb-1. The results are presented as a function of the pT of the leading jet and compared to predictions from leadingand next-to-leading-order event generators combined with parton showers. Measured jet charge distributions, unfolded for detector eects, are reported, which expand on previous measurements of the jet charge average and standard deviation in pp collisions. |
