摘要：

We study multifield tunneling using exact solutions for additive potentials. We introduce a binomial potential with noninteger powers that could be considered a generalization of the 4D Fubini instanton potential. Using scaling arguments, we show that for multifield potentials taller and wider barriers may still lead to a smaller bounce action.
