Dear convenors,

We plan to submit an abstract on measurements of K*0 at BES-II. Please 
find our intended abstract below:

title: Probing hadronic rescattering via $K^{*0}$ resonance production 
at RHIC
Abstract:
The relativistic heavy-ion collisions provide a unique opportunity to 
study the properties of QCD matter at various temperatures and 
densities. Due to their short lifetime resonances (like $K^{*0}$) are 
excellent probes for the medium created in heavy-ion collisions.  
Because of a short lifetime ($\sim$4 fm/c), $K^{*0}$ mesons decay inside 
fireball and their decay daughters are exposed to the in-medium effects 
like rescattering and regeneration. Therefore, properties of $K^{*0}$ 
can be modified by these interactions. On the other hand, because of a 
long lifetime ($\sim$ 42 fm/c), the $\phi$ mesons will mostly decay 
outside of the fireball and therefore their daughters will not have much 
time to rescatter in the  hadronic phase. Hence simultaneous  
measurement of $K^{*0}$ and it's comparision with $\phi$ meson will help 
us to understand the effect of hadronic rescattering on the short-lived 
resonances.
In this talk we will provide the measurement of $K^{*0}$ at 
$\sqrt{s_{NN}}$ = 14.6 and 19.6 GeV using high statistics STAR BES-II 
data. Resonance to non-resonance particle ratios ($\phi/K$ and 
$K^{*0}/K$ ) will be shown as a function of centrality for various beam 
energies. Rapidity dependence of $K^{*0}$ production will be discussed. 
The elliptic flow measurement of $K^{*0}$ at $\sqrt{s_{NN}}$ = 7.7-19.6 
GeV will be presented.

Thanks and Regards
Aswini
