Effect of curvature on confinement-deconfinement phase transition

First order confinement-deconfinement phase transition is studied through hadronic bubble nucleation in an expanding quark-gluon plasma in the context of heavy ion collisions. For this study we consider interacting quark and hadron gas and incorporate the effects of curvature energy. We find that the interactions have the effect of hastening the phase transition whereas the curvature energy has mixed behaviour. Lowering surface tension has the effect of increasing super cooling and slowing down the process of hadronisation in contrast to the case of early Universe. Higher values of bag pressure tend to speed up transition. An interesting feature is the beginning of hadronisation process as soon as the QGP is formed
