Description
We employ a derivative expansion method to analyze the effective action within
the SU(2)-Higgs model at finite temperature. By utilizing a specific power
counting scheme, we compute gauge-invariant constraints on primordial gravi-
tational waves arising from a thermal first-order electroweak phase transition.
We then compare these results with findings from a pre-existing nonperturba-
tive analysis, effectively benchmarking the framework’s validity and assessing its
implications for the detectability of a stochastic gravitational wave background
by forthcoming experiments such as LISA.
