Elliptic flow of strange and multi-strange hadrons in isobar collisions at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV at RHIC

Abstract

We report the elliptic flow ($v_2$) of $K_s^0$, $\Lambda$, $\bar{\Lambda }$, $\varphi$, ${\Xi }^{-}$, and ${\overline{\Xi }}^{+}$ at mid-rapidity for Ru+Ru and Zr+Zr collisions at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV. The transverse momentum ($p_T$) and centrality dependence of $v_2$ have been studied. The number of constituent quark (NCQ) scaling for all the (multi-)strange hadrons has also been tested. The dependence in the ratio of average $v_2$ ($⟨$$v_2$$⟩$) on centrality shows a deviation from unity indicating a difference in nuclear structure and deformation between the isobars. The results show a systematic size dependence when compared to Cu+Cu, Au+Au, and U+U collisions at similar beam energies.
