Study of charged particle production in U-U collisions in the wounded quark model

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 √ s N N = 193 GeV using modified wounded quark model (WQM). At first, we have shown the variation of quark-nucleus inelastic scattering crosssection (σ in qA ) with respect to centralities for various geometrical orientations of U -U collisions in WQM. After that we have calculated the pseudorapidity density (dn ch /dη) within WQM using two-component prescription. Further we have calculated the transverse energy density distribution (dE T /dη) along with the ratio of transverse energy to charged hadron multiplicity (E T /N ch ) for U -U collisions and compared them with the corresponding experimental data. We have shown the scaling behavior of dn ch /dη and dE T

Calculating charged particle observables using modified Wood Saxon model in HIJING for U+U collisions at sNN=193GeV

“…In case of Au (mildly deformed) or Pb (zero deformation), we use Wood-Saxon (WS) distribution to define the distribution of nucleons within the nucleus. For the intrinsically deformed nucleus such as prolate shaped uranium, U, we have included n th ordered deformation parameter, β n , associated with spherical harmonics, Y nl (θ), in the WS function [3][4][5][6][7]. The modified distribution is called modified Wood-Saxon (MWS) density distribution for the nucleons within the nucleus.…”

Exploring the effect of hadron cascade-time on particle production in Xe+Xe collisions at $\sqrt{s_{\rm{NN}}}$ = 5.44 TeV through a multi-phase transport model

“…We use Woods-Saxon (WS) [21] distribution to define the distribution of nucleons inside the spherical nuclei like Au and Pb. Whereas, for the deformed nuclei like Xenon, we have used a modified Woods-Saxon (MWS) density distribution in the HIJING that includes deformation parameter, β n , along with spherical harmonics, Y nl (θ), in the WS function [22][23][24][25][26]. Nucleon density is usually written as a three parameter Fermi distribution [27], which is defined as,…”

“…For the deformed nucleus such as Xenon, we may include deformation parameter, β n , along with spherical harmonics, Y nl (θ), in the WS function [6,[24][25][26][27]. This is known as modified Woods-Saxon (MWS) density distribution.…”
