Resonance and absorption spectra of the Schwarzschild black hole for massive scalar perturbations: a complex angular momentum analysis
Physical Review D 84, 084035 (2011) We reexamine some aspects of scattering by a Schwarzschild black hole in the framework of complex angular momentum techniques. More precisely, we consider, for massive scalar perturbations, the high-energy behavior of the resonance spectrum and of the absorption c...

| description | Physical Review D 84, 084035 (2011) We reexamine some aspects of scattering by a Schwarzschild black hole in the
framework of complex angular momentum techniques. More precisely, we consider,
for massive scalar perturbations, the high-energy behavior of the resonance
spectrum and of the absorption cross section by emphasizing analytically the
role of the mass. This is achieved (i) by deriving asymptotic expansions for
the Regge poles of the $S$-matrix and then for the associated weakly damped
quasinormal frequencies and (ii) by taking into account the analytic structure
of the greybody factors which allows us to extract by resummation the physical
information encoded in the absorption cross section. |
