Abstract
Recent experimental observations of the charged hadron properties in U+U collisions at 193 GeV contradict many of the theoretical models of particle production including two-component Monte Carlo Glauber model. The experimental results show a small correlation between the charged hadron properties and the initial geometrical configurations (e.g. body–body, tip–tip etc.) of U+U collisions. In this article, we have modified the Monte Carlo HYDJET++ model to study the charged hadron production in U+U collisions at 193 GeV center-of-mass energy in tip–tip and body–body initial configurations. We have modified the hard as well as soft production processes to make this model suitable for U+U collisions. We have calculated the pseudorapidity distribution, transverse momentum distribution and elliptic flow distribution of charged hadrons with different control parameters in various geometrical configurations possible for U+U collision. We find that HYDJET++ model supports a small correlation between the various properties of charged hadrons and the initial geometrical configurations of U+U collision. Further, the results obtained in modified HYDJET++ model regarding dn_{ch}/deta and elliptic flow (v_{2}) suitably matches with the experimental data of U+U collisions in minimum bias configuration.
