System size dependence of baryon-strangeness correlation in relativistic heavy ion collisions from a multiphase transport model

The system size dependence of baryon-strangeness (BS) correlations ($C_{BS}$) are investigated with a multiphase transport (AMPT) model for various collision systems from $\mathrm{^{10}B+^{10}B}$, $\mathrm{^{12}C+^{12}C}$, $\mathrm{^{16}O+^{16}O}$, $\mathrm{^{20}Ne+^{20}Ne}$, $\mathrm{^{40}Ca+^{40}Ca}$, $\mathrm{^{96}Zr+^{96}Zr}$, and $\mathrm{^{197}Au+^{197}Au}$ at RHIC energies $\sqrt{s_{NN}}$ 200, 39, 27, 20, 7.7 GeV. Both effects hadron rescattering combination different hadrons play leading role correlations. When the kinetic window is limited to absolute rapidity $|y|>3$, these tend be constant after final-state interaction whatever kind subset we chose based on AMPT framework. correlation found smoothly increase baryon chemical potential $\mu_B$, corresponding or energy quark-gluon-plasma-like phase hadron-gas-like phase. Besides, influence initial nuclear geometrical structures $\alpha$-clustered $\mathrm{^{12}C+^{12}C}$ as well $\mathrm{^{16}O+^{16}O}$ collisions discussed but effect negligible. current studies provide baselines searching signals Quantum Chromodynamics (QCD) transition critical point in heavy-ion through BS correlation.
