Abstract

The multiplicity dependence of the production of the charm mesons in p-p collisions at √(s) = 7 TeV and 13 TeV as measured by ALICE experiment has been investigated using Pythia 8 event generator by studying the effect of various processes at partonic level such as the effect of different modes of color reconnections and rope hadronization. The relative yields (\rm Yield/⟨ Yield ⟩) of D-mesons and J/ψ as a function of relative charged particle multiplicity for various transverse momentum (p\textsubscriptT) ranges as measured by the ALICE experiment are in reasonable agreement with the estimations of Pythia 8 model within the framework of microscopic processes. The relative yields of B mesons for various p\textsubscriptT intervals (1 < p_T < 20 GeV/c) have also been predicted in p-p collisions at √(s) = 7 TeV and √(s) = 13 TeV.
