| dc.description | We find out that baryon numbers of the matter fallen into black holes are rapidly washed-out by investigating the radiation-ball description of the black holes. The radiation-ball solution, which was derived by analyzing the backreaction of the Hawking radiation into space-time and is identified as a black hole, consists of the radiation gravitationally-trapped into the ball and of a singularity. The baryon number of the black hole is defined as that of the radiation in the ball. The sphaleron processes of the Standard Model work in the ball because the proper temperature of the radiation is Planck scale and the Higgs vev becomes zero. The decay-rate of the baryon number becomes \dot{B}/B = -alpha_W^4 / r_BH for the Schwarzschild black hole of radius r_BH. When we assume the baryon number violating processes of the GUT, we find more rapid decay-rate. We can regard the black holes as the baryon-reactors which convert the baryonic matter into energy of radiation. | |
