Description
The inelastic hadronic cross section in proton-lead collisions at a
centre-of-mass energy per nucleon pair of 5.02 TeV is measured with the
CMS detector at the LHC. The data sample, corresponding to an integrated
luminosity of L = 12.6 ± 0.4 nb-1, has been collected
with an unbiased trigger for inclusive particle production. The cross
section is obtained from the measured number of proton-lead collisions
with hadronic activity produced in the pseudorapidity ranges 3 <η < 5 and/or - 5 <η < - 3, corrected for
photon-induced contributions, experimental acceptance, and other
instrumental effects. The inelastic cross section is measured to be
σinel (pPb) = 2061 ± 3 (stat) ± 34 (syst)
± 72 (lumi) mb. Various Monte Carlo generators, commonly used in
heavy ion and cosmic ray physics, are found to reproduce the data within
uncertainties. The value of σinel (pPb) is compatible
with that expected from the proton-proton cross section at 5.02 TeV
scaled up within a simple Glauber approach to account for multiple
scatterings in the lead nucleus, indicating that further net nuclear
corrections are small.
