dc.description.abstractTransverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at sNN−−−√=5.02sNN=5.02 TeVTeV , in the range 0.4<pT<1200.4<pT<120 GeV/cGeV/c and pseudorapidity |ηCM|<1.8|ηCM|<1.8 in the proton–nucleon center-of-mass frame. For pT<10pT<10 GeV/cGeV/c , the charged-particle production is asymmetric about ηCM=0ηCM=0 , with smaller yield observed in the direction of the proton beam, qualitatively consistent with expectations from shadowing in nuclear parton distribution functions (nPDF). A pp reference spectrum at s√=5.02s=5.02 TeVTeV is obtained by interpolation from previous measurements at higher and lower center-of-mass energies. The pTpT distribution measured in pPb collisions shows an enhancement of charged particles with pT>20pT>20 GeV/cGeV/c compared to expectations from the pp reference. The enhancement is larger than predicted by perturbative quantum chromodynamics calculations that include antishadowing modifications of nPDFs.
