Measurement of the Nuclear Modification Factor and Prompt Charged Particle Production in p-Pb and pp Collisions at SQRT(SNN) =5 TeV

The production of prompt charged particles in proton–lead collisions and in proton–proton collisions at the nucleon–nucleon center-of-mass energy SQRT(sNN) = 5 TeV is studied at LHCb as a function of pseudorapidity (eta) and transverse momentum (pT) with respect to the proton beam direction. The nuc...
