Theory seminarPrecise computation of phase-transition parameters
Mikael Chala (Granada U)
I will discuss recent progress in the determination of parameters of first-order thermal-phase transitions, relevant for describing production of gravitational wave backgrounds in the early Universe, using effective field theory (EFT) methods. I will highlight the importance of including previously neglected terms in the EFT expansion and the difficulties and solutions for computing the corresponding corrections to the effective action on non-homogeneous field configurations (e.g. bounce).
