Book Description
(Cont.) In the mid-rapidity region, the yield of charged particles evolves smoothly as a function of [the square root of] sNN and collision centrality. We compare our results with a compilation of data from lower energy p + p, p + A and A + A collisions and discuss their implications for various phenomenological models of particle production.

Book Description
Here, we report measurements of the primary charged-particle pseudorapidity density and transverse momentum distributions in p-Pb collisions at √sNN = 5.02TeV and investigate their correlation with experimental observables sensitive to the centrality of the collision. Centrality classes are defined by using different event-activity estimators, i.e., charged-particle multiplicities measured in three different pseudorapidity regions as well as the energy measured at beam rapidity (zero degree). The procedures to determine the centrality, quantified by the number of participants (Npart) or the number of nucleon-nucleon binary collisions (Ncoll) are described. We show that, in contrast to Pb-Pb collisions, in p-Pb collisions large multiplicity fluctuations together with the small range of participants available generate a dynamical bias in centrality classes based on particle multiplicity. We propose to use the zero-degree energy, which we expect not to introduce a dynamical bias, as an alternative event-centrality estimator. Based on zero-degree energy-centrality classes, the Npart dependence of particle production is studied. Under the assumption that the multiplicity measured in the Pb-going rapidity region scales with the number of Pb participants, an approximate independence of the multiplicity per participating nucleon measured at mid-rapidity of the number of participating nucleons is observed. Furthermore, at high-pT the p-Pb spectra are found to be consistent with the pp spectra scaled by Ncoll for all centrality classes. Our results represent valuable input for the study of the event-activity dependence of hard probes in p-Pb collisions and, hence, help to establish baselines for the interpretation of the Pb-Pb data.

Book Description
Charged-particle multiplicity distributions in 300-GeV/c pd interactions have been determined from an exposure of the Fermi National Accelerator Laboratory 30-in. bubble chamber. The data show clear evidence for double scattering inside the deuterium nucleus. We have been able to correct for the effects of the second scatters using a simple semiempirical model. The resulting pp multiplicity distribution is in excellent agreement with the pp data obtained from a p-H2 experiment at the same energy. The pn multiplicity distribution appears to be shifted from the pp distribution with $\langle$nc$\rangle$ pn=7.84±0.17.
