The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributions in √ s NN = 5.02 TeV lead-lead (PbPb) and proton-proton (pp) collisions recorded with the CMS detector at the LHC. These data correspond to integrated luminosities of 404 µb −1 and 27.4 pb −1 for PbPb and pp collisions, respectively. Leveraging the sensitivity of the jet charge to fundamental differences in the electric charges of quarks and gluons, the jet charge distributions from simulated events are used as templates to extract the quark-and gluon-like jet fractions from data. The modification of these jet fractions is examined by comparing pp and PbPb data as a function of the overlap of the colliding Pb nuclei (centrality). This measurement tests the color charge dependence of jet energy loss due to interactions with the quark-gluon plasma. No significant modification between different centrality classes and with respect to pp results is observed in the extracted quark-and gluon-like jet fractions.

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 p T 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 = 8 TeV corresponding to an integrated luminosity of 19.7 fb −1 . The results are presented as a function of the p T 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 effects, are reported, which expand on previous measurements of the jet charge average and standard deviation in pp collisions.Keywords: Hadron-Hadron scattering (experiments), Jets, Jet substructure, Jet physics The CMS collaboration 23 IntroductionHigh-momentum quarks and gluons (partons) produced at particle colliders form showers of hadrons, which can be clustered into jets to obtain information about the properties of the partons initiating the shower, and hence about the hard scattering causing the jets. A jet is not a fundamental object, but a product of a jet clustering algorithm that depends on the choice of recombination scheme and parameters. Jets can be initiated not only by single high-momentum colored partons, but also multiple partons from the decay of highmomentum top quarks, W, Z, and Higgs bosons, or new particles beyond the standard model. At leading order (LO) in quantum chromodynamics (QCD), we can distinguish the type of partons that initiate jets and refer to them as quark jets, antiquark jets, or gluon jets. To distinguish signal from background, or to characterize a new particle, it is often important to identify the object initiating a jet by means of the properties of the reconstructed particles that define the jet. In particular, the electric charge quantum number of the original parton from which a jet is initiated can be estimated from a momentum-weighted sum of the charges of the particles in the jet [1]. The idea of estimating the charge of a parton from a jet-based observable has a long history. The jet charge observable was suggested initially by Field and Feynman [1]. It was first measured in deep inelastic scattering at Fermilab [2,3], , and Cornell [8] in an effort to understand models of quarks and hadrons. Among its applications were the identification of the charge of b quark jets [9][10][11][12][13][14][15][16], the W boson charge discrimination [17][18][19][20], as well as the determination of the charge of the top quark at the Tevatron [21, 22] and the CERN LHC [23].-1 - JHEP10(2017)131Recent theoretical calculations [24, 25] motivate a more detailed estimation of jet charge and promote its use in new applications. It has been shown that, despite the large experimental uncertainty in fragmentation functions, certain jet charge propert...
