Production of K ∗0 in Au+Au collisions at √S NN = 19.6 GeV from RHIC BES-II
We present the study of K ∗0 in Au+Au collisions at √S NN = 19.6 GeV from RHIC BES-II. The ratio of resonanse to non-resonance ( K ∗0 / K ) is shown as function of centrality and center-of-mass energy, which implies the dominance of hadronic re-scattering over regeneration in central A+A collisions....

| Zusammenfassung: | We present the study of
K
∗0
in Au+Au collisions at √S
NN
= 19.6 GeV from RHIC BES-II. The ratio of resonanse to non-resonance (
K
∗0
/
K
) is shown as function of centrality and center-of-mass energy, which implies the dominance of hadronic re-scattering over regeneration in central A+A collisions. The lower limit of hadronic phase lifetime (

) is also reported using a toy model ansartz. The results are compared with previous RHIC and LHC measurements. |
