Study of multiplicity dependence of heavy flavor production in p-p collisions using rope hadronization mechanism

TL;DR

This study investigates how heavy flavor meson production depends on event multiplicity in proton-proton collisions at high energies, using Pythia 8 simulations with rope hadronization to compare with ALICE experimental data.

Contribution

It introduces a detailed analysis of multiplicity dependence of heavy flavor production using the rope hadronization mechanism in Pythia 8, aligning simulation results with experimental observations.

Findings

Pythia 8 reasonably reproduces ALICE data on D-meson and J/psi yields.

Predictions for B-meson yields at different energies and transverse momenta.

Rope hadronization effects are significant in modeling heavy flavor production.

Abstract

The multiplicity dependence of the production of the charm mesons in p$-$p collisions at $\sqrt{s} = 7$ 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 ($\rm Yield/\langle Yield \rangle$) of D-mesons and $J/\psi$ as a function of relative charged particle multiplicity for various transverse momentum ($p\textsubscript{T}$) 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 $p\textsubscript{T}$ intervals ($1 < p_{T} < 20$ GeV/$c$) have also been predicted in p$-$p collisions at $\sqrt{s} = 7$ TeV and $\sqrt{s} = 13$ TeV.
