Description

The bubble wall velocity is a critical parameter for estimating the gravitational wave signal coming the phase transitions in the early universe. The most precise computations are usually quite involved and require time, which can make then inconvenient for the large use to BSM models. In this talk, I will present two limits, the local thermal equilibrium limit and the relativistic limit, in which this computation can be made almost straightforward. I will discuss applications and limitations of the methods.
