Scattering of scalar tardyons and tachyons from a Schwarzschild black hole.

Abstract

The authors have set up the Klein-Gordon equation in the background of the Schwarzschild curved space-time and studied the scattering of radial tardyons and tachyons from a black hole. They also show that black holes of mass below 7*1014 g may contain bound states of tardyons of pion mass which will be unstable on account of the presence of an attractive r-4 term.
