Study of the transverse momentum distribution of transport models of kaon, Pion, and (anti-)proton production in U+U collisions at $\sqrt{s_{NN}}$ = 193 GeV

Abstract: In this study, the transverse momentum spectra of $k ^{\pm }$, $\pi ^{\pm }$ and $p(\bar{p})$ particles in mid-rapidity ($\left | y \right | < 0.1$) for nine centrality classes are investigated in $^{238} U$+$^{238} U$ collisions at $\sqrt{s_{NN}}$=193 GeV within the cascade and soft momentum-dependent equation of state (SM-EoS) mode of the UrQMD model. Other extracted observable from $p_{T}$ spectrum includes average transverse momentum ($\left \langle p_{T} \right \rangle$), the yield ($dN/dy$) as well as the ratio of particle type are also shown in function of collision centrality. It is found that the U+U collision process is segmented. Before the collision centrality is $50-60\%$, the experimental data are described well using cascade mode when the $p_{T} < 1.2 GeV/c$. The results are in good agreement with the experimental data using the SM-EoS mode at $p_{T} > 1.2 GeV/c$. For the case of $60-80\%$ centrality, the SM-EoS mode describes the data better. At RHIC energy, pair production is the dominant production mechanism for particles, with the anti-ion to ion yield ratio suggesting.
