Study of relativistic charged particle production using multi-source thermal model and emission feature of slowest target protons

In this manuscript we have mainly focused our study on the multiplicity distributions of projectile fragments and slowest target protons (black particles) released during the interaction of \(^{84}Kr\) with emulsion at 1 A GeV and their dependency on various target groups of the nuclear emulsion. In case of projectile fragments these distributions are described and have been replicated using a multi-source thermal model. The model makes the premise that collisions produce a large number of particle sources. Like a radioactive item, each source contributes a multiplicity distribution. The observations of the present study shows that the theoretical calculations utilising the multi-source thermal model and the experimental findings are in good agreement. In case of slowest target protons this study reveals a striking relationship between the target fragmentation processes and collision geometry with multiplicity distributions.
