In medium effects on the $\varphi$ meson

Abstract

The temperature dependence of the $\varphi$ meson mass and its decay width ($\varphi \to K\bar{K}$)have been studied from an effective non-linear chiral Lagrangian in $SU(3)$. Effective mass has been obtained from the pole position of the full propagator. The width has also been calculated. It has been found that the mass decreases with temperature very slowly whereas the decay width increases quite sharply. Possible consequence on the QGP signals is discussed.
