$J/Ψ$ suppression in an expanding hadron gas
Abstract
Description
A model for $J/Ψ$ suppression at a high energy heavy ion collision is presented. The main (and the only) reason for the suppression is $J/Ψ$ inelastic scattering within hadron matter. The hadron matter is in the form of a multi-component non-interacting gas. Also the evolution of the gas, both longitudinal and transverse, is taken into account. It is shown that under such circumstances and with $J/Ψ$ disintegration in nuclear matter added, $J/Ψ$ suppression evaluated agrees well with NA38 and NA50 data.
