However, recent STAR measurements indicate a system-size dependence in the $v_1(y)$-slope ($dv_{1}/dy$) of protons, antiprotons, and their differences ($\\Delta dv_{1}/dy$) at a given centrality, suggesting a potential influence of baryon production and transport mechanisms~\\cite{Taseer:SQM2024talk}.
