Effect of hadronic interaction on the flow of $K^{\ast 0}$

Abstract

We explore the implications of the late stage hadronic rescattering phase on the flow of $K^{\ast 0}$. The model calculations are done using a (3+1)-dimensional hybrid framework, incorporating both hydrodynamic evolution and hadronic transport that is calibrated to agree with bulk observables including the elusive rapidity differential $v_1$ of light-flavor hadrons. We find that the late stage hadronic rescattering phase causes significant qualitative modification of the $K^{\ast 0}$ $v_1$ resulting in $\frac{d{v}_1}{dy}(K^{\ast 0})-\frac{d{v}_1}{dy}(K^{+})$ and $\frac{d{v}_1}{dy}(\varphi )-\frac{d{v}_1}{dy}(K^{+})$ to have opposite signs with the effect being more pronounced in central collisions as compared to peripheral ones due to the larger multiplicity as well as longer duration of the hadronic phase. Further, this effect is enhanced in low-energy collisions owing to a stronger breaking of boost invariance. On the contrary, the influence of the hadronic phase on the $K^{\ast 0}$ elliptic flow $v_2$ is found to be less significant and quantitative.
