Phys. Rev. D 78, 101502(R) (2008) [4 pages]Bounding the greybody factors for Schwarzschild black holes
Greybody factors in black-hole physics modify the naive Planckian spectrum that is predicted for Hawking radiation when working in the limit of geometrical optics. We consider the Schwarzschild geometry in (3+1) dimensions, and analyze the Regge-Wheeler equation for arbitrary particle spin s and wave-mode angular momentum ℓ, deriving rigorous bounds on the greybody factors as a function of s, ℓ, wave frequency ω, and the black-hole mass m. © 2008 The American Physical Society URL:
