Measurement of jet charge observables in dijet events at $\sqrt{s}=8~\mathrm{TeV}$

Jet charge is an estimator for the electric charge of a quark, antiquark or gluon initiating a jet. It is based on the momentum-weighted sum of the measured electric charges of the jet constituents. A measurement of three different charge observables of the leading jet is performed in dijet events. The analysis is carried out with a data sample of $19.7~\mathrm{fb}^{-1}$ collected in proton-proton collisions at $\sqrt{s}=8~\mathrm{TeV}$. The results are presented differentially in transverse momentum of the leading jet and compared to predictions from QCD-inspired leading order event generators. This is the first CMS measurement of jet charge observables unfolded for detector effects.
