Study of Target Dependence of Clan Model Parameter in 84^Kr_36 - Emulsion Interactions at 1 GeV per nucleon

TL;DR

This study investigates how clan model parameters depend on target types in nuclear emulsion interactions with 84Kr at 1 GeV per nucleon, revealing scaling behavior and target-dependent multiplicity variations.

Contribution

It provides new insights into target dependence of clan model parameters and their scaling behavior in heavy-ion emulsion interactions at intermediate energies.

Findings

Experimental points follow negative binomial distribution.

Average clan multiplicities increase with pseudo-rapidity interval.

Target type influences average particle multiplicity and clan size.

Abstract

The article focuses on study of clan model parameters and their target dependence in light of void probability scaling for heavy (Ag and Br) and light (C, N and O) groups of targets present in nuclear emulsion detector using 84 Kr 36 at around 1 A GeV. The variation of scaled rapidity gap (rap gap) probability with single moment combination has been studied. We found that experimental points are lying approximately on the negative binomial distribution (NBD) curve, indicating a scaling behavior. The average clan multiplicities for interactions, increases with the pseudo-rapidity interval was also observed. The values of average multiplicity for AgBr targets are larger than those for CNO target and also average number of particles per clan increases with increase in pseudo-rapidity interval. We further observed that for a particular target, average number of particles per clan increases with an increase in the size of projectile nucleus.
