Abstract

In this paper we report the minimum bias differential yields of primary charged particles ${\pi }^{\pm }$, $K^{\pm }$, $p,\overline{p}$, strange particles $K_S^0,$$\mathrm{\Lambda },\overline{\mathrm{\Lambda }},$${\mathrm{\Xi }}^{\pm }$ and ${\mathrm{\Omega }}^{\pm },$ produced in $Xe-Xe$ collisions at $\sqrt{s_{\mathit{NN}}}=5.44TeV$ as a function of $p_T$ in kinematic range of $0<p_T<6GeV/c$ and pseudorapidity region of $|\eta |<0.8$ using PYTHIA8 and HIJING2 event generators. The predictions are compared with ALICE data at the LHC. The PYTHIA8 predictions describe the ALICE data at low $p_T$ values and underestimate them at high $p_T$ values. PYTHIA8 model is tuned to color reconnection (CR) for hadronization by minimizing the string length of partons, where it gives significant results within $1.9<p_T<3.5GeV/c$ region. The HIJING2 predictions show a good agreement with ALICE data. We have found that the integrated yield of strange and multistrange hadrons, relative to pions, kaons and protons, increases significantly with $p_T$.
