Contribution

It applies the wounded nucleon model to analyze pion multiplicities in relativistic heavy-ion collisions, highlighting mass dependence and linear relationships.

Findings

Charged pion multiplicity depends on projectile and target mass.

Mean multiplicity increases linearly with projectile mass number.

Multiplicities are independent of incident energy.

Abstract

This article is focused on the multiplicity and probability distribution of the emitted charged pions <N_{\pi}> for interaction of ^{84}Kr_{36} projectile with nuclear emulsion targets at kinetic energy 1 GeV per nucleon. In the wounded nucleon model frame work, we have calculated the total number of wounded nucleons (W) and total number of interactions ({\nu}). The obtained results revealed that the average multiplicity of the charged pions <N_{\pi}> is dependent on the projectile and target mass. The calculated values of the wounded nucleons (W) and total number of interactions ({\nu}) shows strong dependence on the mass of the colliding nuclei. The emission rate of mean multiplicity of the <N_{s}> and <N_{\pi}> increases with increasing the total number of wounded nucleons (W) and total number of interactions ({\nu}). The mean multiplicity value of <N_{s}> and <N_{\pi}> linearly increases with increasing the projectile mass number (A_{P}) and independent of the incident energy.
