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 √sNN = 193 GeV using the modified wounded quark model (WQM). At first,
we have shown the variation of quark-nucleus inelastic scattering cross-section (σin
qA) with respect to centralities for various geometrical orientations of U-U collisions in WQM. After that we have calculated the
pseudorapidity density (dnch/dη) within WQM using a two-component prescription. Further we have calculated the transverse energy density distribution (dET/dη) along with the ratio of transverse energy to
charged hadron multiplicity (ET /Nch) for U-U collisions and compared them with the corresponding experimental data. We have shown the scaling behavior of dnch/dη and dET/dη for different initial geometry
of U-U collision with respect to p-p data at √sNN = 200 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 200 GeV. 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.
