We examine the absorption cross section of the massive scalar field for the higher-dimensional extended object. Adopting the usual quantum mechanical matching conditions between the asymptotic and near-horizon solutions we check whether or not the universal property of the absorption cross section, which is that the low-energy cross section is proportional to the surface area of horizon, is mai...

We examine the absorption cross section of the massive scalar field for the higher-dimensional extended object. Adopting the usual quantum mechanical matching conditions between the asymptotic and near-horizon solutions in radial equation, we check whether or not the universal property of the absorption cross section, which is that the low-energy cross section is proportional to the surface are...

متن کاملAbsorption Cross Section of Scalar Field in Supergravity Background
It has recently been shown that the equation of motion of a massless scalar field in the background of some specific p branes can be reduced to a modified Mathieu equation. In the following the absorption rate of the scalar by a D3 brane in ten dimensions is calculated in terms of modified Mathieu functions of the first kind, using standard Mathieu coefficients. The relation of the latter to Do...
متن کاملLow-Energy Absorption Cross Section for massive scalar and Dirac fermion by (4 + n)-dimensional Schwarzschild Black Hole
Motivated by the brane-world scenarios, we study the absorption problem when the spacetime background is (4 + n)-dimensional Schwarzschild black hole. We compute the low-energy absorption cross sections for the branelocalized massive scalar, brane-localized massive Dirac fermion, and massive bulk scalar. For the case of brane-localized massive Dirac fermion we introduce the particle’s spin in t...
