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.

abstract
Pure Lovelock black holes are geometrically more transparent than their Einstein counterparts, but they radiate far less. We compute scalar and higher-dimensional electromagnetic greybody factors and Hawking spectra on the critical branch $d=2N+2$, compare them with Schwarzschild--Tangherlini black holes at the same horizon radius $r_h$, and show that the smaller Hawking temperature overwhelms the enhanced transmission. In the benchmark $d=6$ case, the integrated scalar and electromagnetic powers are reduced by about $10^{-3}$ and $10^{-5}$, respectively. We also find a clean higher-curvature signature: as the Lovelock order $N$ grows, Hawking radiation becomes increasingly dominated by the scalar-type electromagnetic sector.

Compares surface-gravity, Bousso-Hawking, and effective temperatures for the Gao-Zhang dilaton-de Sitter black hole and shows order-of-magnitude differences in radiation estimates.
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.
Numerical study of holonomy-corrected Schwarzschild black holes finds enhanced low-frequency scalar transmission but overall suppressed Hawking radiation, with electromagnetic channel most quenched.
