Multiplicity, transverse momentum and pseudorapidity dependence of open-heavy flavored hadron production in proton+proton collisions at √s = 13 TeV using PYTHIA8

Abstract

Recently, with the upgradation of LHC, it is realized that study of heavy-flavored hadrons, namely Λc+ and D0 in hadronic collisions, could reveal the possibility of thermalization of charm quarks. With this motivation, we study the production dynamics of these hadrons using a pQCD-inspired Monte Carlo event generator called PYTHIA8 in proton+proton collisions at √s=13TeV. The production dynamics of these hadrons are analyzed through charged-particle multiplicity, transverse momentum and pseudorapidity. With the help of the established PYTHIA8 tunes to mimic the behavior of flow-like features, we investigated the variation of effective temperature and degree of nonextensivity using thermodynamically consistent nonextensive Tsallis statistics. We further attempted to establish a connection between the initial state and final state by estimating the correlation between the number of multi-partonic interactions (nMPI) with the Knudsen number. © 2024 World Scientific Publishing Company.
