Description

Various nuclei, like Cu, Au, Pb, and U, have collided in various relativistic heavy-ion colliders to comprehend the medium of de-confined quarks and gluons called Quark-Gluon Plasma (QGP). The STAR 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 and multiplicity. All these colliding nuclei are observed to have different shapes and structures, which might also influence particle production. These collisions can be modeled using different configurations of Woods-Saxon (WS) distribution using the AMPT model and studying the influence of nuclear geometry on the particle production mechanisms.

In this talk, we will present transverse momentum spectra of pions, kaons, and (anti-)protons at mid-rapidity ($\lvert y \rvert$ $<$ 0.5) 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 influence of various WS parametrizations 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.
