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 ( v 1 even ) 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 s NN = 200 GeV. Our analysis demonstrates that the eccentricity ϵ ₁, v 1 even and K exhibit subtle yet discernible sensitivity to the input nuclear structure distinctions between ⁹⁶Ru and ⁹⁶Zr isobars. This observation suggests that measuring v 1 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.
