Exploring Rapidity-Even Dipolar Flow in Isobaric Collisions at RHIC

Abstract

Employing the AMPT transport model, we investigate the response of the rapidity-even dipolar flow (${\mathrm{v}}_1^{\mathrm{even}}$) and its associated Global Momentum Conservation (GMC) parameter $\mathrm{K}$ to structural disparities within ${}^{96}$Ru and ${}^{96}$Zr nuclei. We analyze $\mathrm{Ru}+\mathrm{Ru}$ and $\mathrm{Zr}+\mathrm{Zr}$ collisions at a center-of-mass energy of $\sqrt{{\text{s}}_{NN}}$ = 200 GeV. Our analysis demonstrates that the eccentricity ${\epsilon }_1$, ${\mathrm{v}}_1^{\mathrm{even}}$ and $\mathrm{K}$ exhibit subtle yet discernible sensitivity to the input nuclear structure distinctions between ${}^{96}$Ru and ${}^{96}$Zr isobars. This observation suggests that measuring $v_1^{\mathrm{even}}$ and the GMC parameter in these isobaric collisions could serve as a means to fine-tune the comprehension of their nuclear structure disparities and offer insights to enhance the initial condition assumptions of theoretical models.
