Study of charged particle multiplicity, average transverse momentum and azimuthal anisotropy in Xe+Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV using AMPT model

We have studied the average charged particle density ($\lt dN_{ch}/d\eta \gt$), transverse momentum ($p_{\mathrm{T}}$) spectra, $<p_{\mathrm{T}}>$ and azimuthal anisotropies of inclusive charged particles produced in Xe+Xe collisions a t $\sqrt{s_{NN}}$ = 5.44 TeV using A Multiphase Transport...

Sumario:We have studied the average charged particle density ($\lt dN_{ch}/d\eta \gt$), transverse momentum ($p_{\mathrm{T}}$) spectra, $<p_{\mathrm{T}}>$ and azimuthal anisotropies of inclusive charged particles produced in Xe+Xe collisions a t $\sqrt{s_{NN}}$ = 5.44 TeV using A Multiphase Transport Model (AMPT), which includes the deformation of Xe$^{129}$ nucleus. Calculations have been performed w ith the string melting version of AMPT model and compared with the recent measurements from the ALICE experiment. The model results over predict the measured $<dN_{ch}/d\eta>$ for central collisions, agree with the data for mid-central collisions and under predict the measurements for peripheral collisions. The centrality dependence of $<p_{\mathrm{T}}>$ of charged particles measured in ALICE is not reproduced by the model results. The calculated elliptic flow ($v_{2}$) from AMPT model overpredicts the ALICE measurements in central collisions but are consistent with the data in mid central collisions. We find that the model shows a mild centrality dependence of triangular flow and overestimates the ALICE measurements. Within the model framework, we have also studied various collision configurations of Xe nuclei such as body-body, tip-tip, side-side and random. We find a strong dependence of the above observable on the collision configurations.
