Low-frequency scattering calculations show scalar probes through the MMP wormhole are mostly reflected or trapped at early times with late leakage to half the black-hole cross-section, while charged massless fermions transmit with unit probability via a Callan-Rubakov-like channel.

abstract
In this paper we compute the low energy absorption cross-section for minimally coupled massles scalars and spin-$1/2$ particles, into a general spherically symmetric black hole in arbitrary dimensions. The scalars have a cross section equal to the area of the black hole, while the spin-$1/2$ particles give the area measured in a flat spatial metric conformally related to the true metric.

Numerical computation of absorption cross sections for massive Proca fields on Schwarzschild black holes, revealing mass-induced longitudinal modes and breaking of even-odd parity degeneracy in transmission spectra.
Numerical greybody factors for photons and massless Dirac fields in Simpson-Visser and Casadio-Fabbri-Mazzacurati geometries reveal that WKB overestimates luminosities by orders of magnitude near wormhole endpoints, increasing a Simpson-Visser lifetime coefficient by a factor of about 85.
Numerical greybody factors for the Dymnikova black hole show temperature-driven luminosity suppression near the extremal remnant, with increasing fermion dominance in the residual massless flux.
Derives static spherically symmetric black hole metric combining ModMax electrodynamics, Lorentz-violating Kalb-Ramond gravity, and perfect-fluid dark matter, then analyzes thermodynamic quantities and stability.
