In medium effects on the $\phi$ meson

Nuclear Theory 2008-11-26 v1

Abstract

The temperature dependence of the ϕ\phi meson mass and its decay width (ϕKKˉ\phi \rightarrow K \bar{K})have been studied from an effective non-linear chiral Lagrangian in SU(3)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.
