We scrutinize the recent Letter "Gravitational pair production and black hole evaporation" by M.F. Wondrak, W.D. van Suijlekom and H. Falcke [Phys. Rev. Lett. 130, 221502 (2023); arXiv:2305.18521]. We show that some consequences based on the proposed imaginary part of the lowest order effective action are in sharp tension with exact results on pair creation in electrodynamics and cosmology. This casts serious doubt on their claims for particle production in a Schwarzschild spacetime.

  1. Particle production from bubble collisions

    hep-ph 2026-07 conditional novelty 8.0 of 10

    Heavy particles are produced in bubble-wall collisions by on-shell partonic scatterings, not by off-shell decay of the classical field, so the earlier rates and their phenomenological signals are parametrically overestimated.

  2. Nonlocal effective action and particle creation in $D$ dimensions

    hep-th 2024-12 accept novelty 6.0 of 10

    The vacuum-persistence probability for a quantum field in a weak gravitational background is computed to second order in curvatures in D dimensions; conformal fields in conformally flat spacetimes do not create partic...
