Exploring Rapidity-Even Dipolar Flow in Isobaric Collisions at RHIC

Employing the AMPT transport model, we investigate the response of the rapidity-even dipolar flow ( v1even ) and its associated Global Momentum Conservation (GMC) parameter K to structural disparities within 96Ru and 96Zr nuclei. We analyze Ru + Ru and Zr + Zr collisions at a center-of-mass energy of sNN = 200 GeV. Our analysis demonstrates that the eccentricity epsilon 1, v1even and K exhibit subtle yet discernible sensitivity to the input nuclear structure distinctions between 96Ru and 96Zr isobars. This observation suggests that measuring v1even 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.
