Dynamical growth of the hadron bubbles during the quark-hadron phase transition - art. no. 014012

The rare of dynamical growth of the hadron bubbles in a supercooled baryon free quark-gluon plasma is evaluated by solving the equations of relativist ic fluid dynamics in all regions. For a nonviscous plasma, this dynamical g rowth rate is found to depend only on the range of correlation xi of order parameter fluctuation, and the radius R of the critical hadron bubble, the two length scales relevant for the description of the critical phenomena. F urther, it is shown that the dynamical prefactor acquires an additive compo nent when the medium becomes viscous. Interestingly, under certain reasonab le assumptions for the velocity of the sound in the medium around the saddl e configuration, the viscous and the nonviscous parts of the prefactor are found to be similiar to the results obtained by Csernai and Kapusta and Rug geri and Friedman (for the case of zero viscosity), respectively.
