Multiparticle production in high-energy deformed nuclei collisions in the framework of the modified Glauber model

In this paper, we present the results of further development of the Monte Carlo modified Glauber model (MGM) for deformed nuclei collisions at high energy. Our model differs from the Standard Glauber model by effective account of energy losses in successive nucleon–nucleon collisions; we also account for the associated decrease in the inelastic nucleon–nucleon interaction cross-section. The case of deformed nuclei appears to be interesting because nuclei orientation before collision — whether it is of a tip-on-tip type or side-on-side type — was expected to affect significantly the multiparticle production. We discuss our results, obtained in the framework of the MGM with only one parameter, and compare them at the LHC energies, to the effects of nonlinearity observed for the normalized charged particle yields versus centrality in collisions of deformed nuclei: [Formula: see text] and [Formula: see text]. We compare the results to the case of [Formula: see text] collisions and argue that the explanation of these nonlinear effects in total multiplicity yields is purely geometrical and the role of deformation is not the main one.
