Diffusion of hidden charm mesons in hadronic medium

TL;DR

This paper investigates how hidden charm mesons diffuse in a hot hadronic medium by calculating their transport coefficients, revealing that temperature increases these coefficients but have limited impact on J/psi suppression.

Contribution

The study provides new calculations of drag and diffusion coefficients for hidden charm mesons using effective theory and scattering lengths, enhancing understanding of their behavior in hadronic matter.

Findings

Transport coefficients increase significantly with temperature.

Effects on J/psi suppression are minimal despite higher transport coefficients.

Provides quantitative data for charm meson diffusion in hadronic environments.

Abstract

The drag and diffusion coefficients of a hot hadronic medium have been evaluated by using hidden charm mesons as probes. The matrix elements for the evaluation of these coefficients are calculated using an effective theory as well as from scattering lengths. Although the transport coefficients show a significant rise with temperature its effects on the suppression of $J/\psi$ in hadronic matter is not significant.
