Description
In this talk, we studied heavy particle production from bubble collisions, and we show that by analyzing the trapping equation, the efficiency factor in the high-frequency regime behaves as $f(\chi) \sim \chi^{-4}$, a result we then generalize to $3+1$ dimensions while confirming the same power-law suppression.
