  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 sqrt(s) = 8 TeV
corresponding to an integrated luminosity of 19.7 inverse femtobarns. The
results are presented as a function of the pT of the leading jet and compared
to predictions from leading- and next-to-leading-order event generators
combined with parton showers. Measured jet charge distributions, unfolded for
detector effects, are reported, which expand on previous measurements of the
jet charge average and standard deviation in pp collisions.
