Description
One of the primary goals of studying heavy-ion collisions has been to comprehend a medium of de-confined quarks and gluons called Quark-Gluon Plasma (QGP). Various nuclei, like Cu, Au, Pb, and U, have been collided in various relativistic heavy-ion colliders to decipher the properties of this medium and the corresponding particle production in these collisions. All these nuclei are observed to have various shapes and structures, which might also influence particle production. Recently, the STAR experiment at RHIC recorded data for isobar, Ru+Ru, and Zr+Zr, collisions at $\sqrt{s_{\mathrm {NN}}}$ = 200 GeV, provide hints of different nuclear structure between the two isobar nuclei through collective flow. These nuclei can be modeled using different configurations of Woods-Saxon (WS) distribution using the AMPT model and study the influence of nuclear geometry on the particle production mechanisms.
In this talk, we will present transverse momentum ($p_{T}$) spectra of pions, kaons, and (anti-)protons at mid-rapidity ($| y |$ $<$ 1.0) for Ru+Ru, Zr+Zr, Au+Au and U+U collisions at $\sqrt{s_{\mathrm {NN}}}$ = 200 GeV using a multi-phase transport (AMPT) model. The effect of various parameterizations of WS distribution on $p_{T}$-spectra, particle yield ($dN/dy$), mean transverse momentum ($\langle p_{T}\rangle$), and particle ratios will be discussed. The system size dependence of $dN/dy$ and $\langle p_{T}\rangle$ with different colliding systems will be presented. In addition, the physics implications of such studies in the context of nuclear structure in isobars will be highlighted.
