Soft QCD measurements with ALICE

초록

Particle production at LHC energies involves perturbative (hard) and non-perturbative (soft) QCD regimes. At low transverse momentum it is generally described by phenomenological models. In this contribution, we report on soft QCD variables, such as inelastic, single- and double-diffractive cross sections, charged-particle multiplicity density and observables characterising the Underlying Event. Results are presented for data from pp, p-Pb, Xe-Xe and Pb-Pb collisions at LHC energies reconstructed with the ALICE detector. The evolution of particle production with energy and system size is discussed. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
