abstract

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

  1. Large-Field Vacuum Decay in General Multi-Scalar Theories

    hep-ph 2026-07 conditional novelty 7.0 of 10

    In the large-field limit, multi-scalar vacuum decay is dominated by a radial (straight-line) bounce, reducing the calculation to minimizing an effective quartic coupling.
