Description
We present a systematic computation of bubble nucleation rates for cosmological first-order phase transitions within a strict EFT expansion obtained through dimensional reduction and the integration of fields heavier than the nucleation scale. The calculation consistently separates contributions from the leading EFT potential, higher-order operators generated by consecutive matching steps, and fluctuation determinants around the critical bubble. This framework allows us to compare the relative impact of full determinant prefactors and higher-dimensional operators while maintaining controlled power counting.
