Abstract

We explore the implications of the late stage hadronic rescattering phase on the flow of K0K^{*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 v1v_1 of light-flavor hadrons. We find that the late stage hadronic rescattering phase causes significant qualitative modification of the K0K^{*0} v1v_1 resulting in dv1dy(K0)dv1dy(K+)\frac{dv_1}{dy}(K^{*0})-\frac{dv_1}{dy}(K^{+}) and dv1dy(ϕ)dv1dy(K+)\frac{dv_1}{dy}(\phi)-\frac{dv_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 K0K^{*0} elliptic flow v2v_2 is found to be less significant and quantitative.
