    • Abstract

       

      We calculate the interfacial surface tension of a QGP-fireball in a hadronic medium in the Ramanathan et al statistical model. The constancy of the ratio of the surface tension with the cube of the critical transition temperature is in overall accordance with lattice QCD findings. It is in complete agreement with a recent MIT bag model calculation of surface tension. The velocity of sound in the QGP droplet is predicted to be in the range $(0.27 \pm 0.02)$ times the velocity of light in vacuum and this value is independent of both the value of the transition temperature and the model parameters.
