The charged-particle pseudorapidity density (dN ch /dη) for p(p)+p, p+A and A+A(B) collisions and the mean multiplicity N ch for e − +e + , e ± +p, and p(p)+p collisions are studied for a wide range of beam energies ( √ s). Characteristic scaling patterns are observed for both dN ch /dη and N ch , consistent with a thermal particle production mechanism for the bulk of the soft particles created in all of these systems. The scaling patterns found also validate an essential role for quark participants in these collisions. The measured values for dN ch /dη and N ch are observed to factorize into contributions that depend on log( √ s) and the number of nucleon or quark participant pairs N pp . The quantification of these contributions gives expressions that serve to systematize dN ch /dη and N ch measurements spanning nearly 4 orders of magnitude in √ s and to predict their values as a function of √ s and N pp .

Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at √ s = 0.9 and 2.36 TeV. The data were collected with the CMS detector during the LHC commissioning in December 2009. For non-single-diffractive interactions, the average charged-hadron transverse momentum is measured to be 0.46 ± 0.01 (stat.) ± 0.01 (syst.) GeV/c at 0.9 TeV and 0.50 ± 0.01 (stat.) ± 0.01 (syst.) GeV/c at 2.36 TeV, for pseudorapidities between −2.4 and +2.4. At these energies, the measured pseudorapidity densities in the central region, dN ch /dη| |η|<0.5 , are 3.48 ± 0.02 (stat.) ± 0.13 (syst.) and 4.47 ± 0.04 (stat.) ± 0.16 (syst.), respectively. The results at 0.9 TeV are in agreement with previous measurements and confirm the expectation of near equal hadron production in pp and pp collisions. The results at 2.36 TeV represent the highest-energy measurements at a particle collider to date.

Abstract:The global properties of the final states produced in hadronic interactions of protons at centre-of-mass energies of future hadron colliders (such as FCC-hh at CERN, and SppC in China), are studied. The predictions of various Monte Carlo (MC) event generators used in collider physics (pythia 6, pythia 8, and phojet) and in ultrahighenergy cosmic-rays studies (epos, and qgsjet) are compared. Despite their different underlying modeling of hadronic interactions, their predictions for proton-proton (p-p) collisions at √ s = 100 TeV are quite similar. The average of all MC predictions (except phojet) for the different observables are: (i) p-p inelastic cross sections σ inel = 105 ± 2 mb; (ii) total charged multiplicity N ch = 150 ± 20; (iii) charged particle pseudorapidity density at midrapidity dN ch /dη| η=0 = 9.6 ± 0.2; (iv) energy density at midrapidity dE/dη| η=0 = 13.6 ± 1.5 GeV, and dE/dη| η=5 = 670 ± 70 GeV at the edge of the central region; and (v) average transverse momenta at midrapidities p T = 0.76 ± 0.07 GeV/c. At midrapidity, epos and qgsjet-ii predict larger per-event multiplicity probabilities at very low (N ch < 3) and very high (N ch > 100) particle multiplicities, whereas pythia 6 and 8 feature higher yields in the intermediate region N ch ≈ 30-80. These results provide useful information for the estimation of the detector occupancies and energy deposits from pileup collisions at the expected large FCC-hh/SppC luminosities.
