Description
Strongly coupled theories which can undergo a thermal first order phase transition are of phenomenological interest, for example as dark matter candidates. Furthermore, they are potential sources of a stochastic gravitational wave background.
As a prototype for models with a confinement transition, we study the deconfinement transition of SU(8) pure gauge model with 4D multicanonical lattice simulations. We present results for the critical bubble probability and compare it to results from thin wall calculations. We also compare the effectiveness of different lattice pseudo-order parameters at identifying the bubble configurations and discuss whether our 'critical' bubble configurations are truly critical.
