Abstract

Recently, there has been a growing interest in the study of deformed uranium-uranium (U-U) collisions in its various geometrical configurations due to their usefulness in understanding the different aspects of quantum chromodynamics (QCD). In this paper we have studied the particle production in deformed U-U collisions at GeV using the modified wounded quark model (WQM). At first, we have shown the variation of quark-nucleus inelastic scattering cross-section ( with respect to centralities for various geometrical orientations of U-U collisions in WQM. After that we have calculated the pseudorapidity density ( within WQM using a two-component prescription. Further we have calculated the transverse energy density distribution ( along with the ratio of transverse energy to charged hadron multiplicity ( for U-U collisions and compared them with the corresponding experimental data. We have shown the scaling behavior of and for different initial geometry of U-U collision with respect to p -p data at GeV. Furthermore we have shown the Bjorken energy density achieved in U-U collisions for various configurations and compared them with experimental data of Au-Au at 200GeV. We observe that the present model suitably describes the experimental data for minimum bias geometrical configuration of U-U collisions. An estimate for various observables in different initial geometries of U-U collisions is also presented which will be tested in future by experimental data.
