Abstract
The temperature dependence of the phi meson mass and its decay width ( phi-->K (K) over bar) have been studied from an effective nonlinear ch iral Lagrangian in SU(3). The effective mass has been obtained from th e pole position of the full propagator. The width has also been calcul ated. It has been found that the mass decreases with temperature very slowly whereas the decay width increases quite sharply. Possible conse quences on the QGP signals are discussed.
