Description
We present the in-medium modification of pentaquark , $\Theta^+$, using chiral SU(3) hadronic mean field model in hot and dense asymmetric nuclear matter. The in-medium properties of hadrons within the chiral model are investigated through the modification of scalar fields $\sigma$, $\zeta$ and $\delta$ and the vector fields $\omega$ and $\rho$. The effects of finite temperature and density of the medium are evaluated considering $\Theta^+$ as $n K^+ \pi^0$ and $p K^0 \pi^0$ structure. For the in-medium masses of kaons $K^+$ and $K^0$, which are used as input in calculations of effective mass of $\Theta^+$, we employ chiral SU(3) model and chiral perturbation theory in asymmetric nuclear matter and a comparison of results is presented.
