Narrow Results

Different aspects like multiplicity moments, $D_q$ moments and multiplicity fluctuations in terms of scaled variance of the shower particles has been carried out for central events of ${}^{16}\mathrm{\text{O}}-\mathrm{\text{AgBr}}$, ${}^{22}\mathrm{\text{Ne}}-\mathrm{\text{AgBr}}$ and ${}^{32}\mathrm{\text{S}}-\mathrm{\text{AgBr}}$ interactions at (4.1–4.5) AGeV/c. Comparison of our results with different experimental analysis of central collisions of emulsion data has been performed whenever available.

A detailed study on the centrality dependence of the different aspects multiplicity distribution of the shower particles produced in the backward direction (${𝜃}_{\mathrm{\text{Lab}}}\ge 90^{\circ })$ in nuclear emulsion track detector has been carried out for ${}^{22}$Ne-emulsion interactions at 4.1 AGeV/c. Depending on the values of the total charges or sum of the charges of noninteracting projectile fragments, event samples were classified into four centrality classes. From the analysis presented in this paper, qualitative information about the assembly of shower particles in the backward direction has been extracted.
