Abstract

The transverse momentum (Formula presented.) distribution of primary charged particles is measured at midrapidity in minimum-bias p–Pb collisions at (Formula presented.)NN = 5.02(Formula presented.) TeV with the ALICE detector at the LHC in the range. The spectra are compared to the expectation based on binary collision scaling of particle production in pp collisions, leading to a nuclear modification factor consistent with unity for (Formula presented.) larger than 2 GeV/(Formula presented.)(Formula presented.) around 4 (Formula presented.). The measurement is compared to theoretical calculations and to data in Pb–Pb collisions at (Formula presented.) TeV.
