The transverse momentum (pT) distribution of primary charged particles is measured in minimum bias (non-single-diffractive) p + Pb collisions at √ sNN = 5.02 TeV with the ALICE detector at the LHC. The pT spectra measured near central rapidity in the range 0.5<pT < 20 GeV/c exhibit a weak pseudorapidity dependence. The nuclear modification factor R(pPb_ is consistent with unity for pT above 2 GeV/c. This measurement indicates that the strong suppression of hadron production at high pT observed in Pb + Pb collisions at the LHC is not due to an initial-state effect. The measurement is compared to theoretical calculations.

Abstract

The transverse momentum (pT) distribution of primary charged particles is measured in minimum bias (non-single-diffractive) p + Pb collisions at √ sNN = 5.02 TeV with the ALICE detector at the LHC. The pT spectra measured near central rapidity in the range 0.5
