DECAY OF MASSIVE DIRAC HAIRS ON BRANE-WORLD BLACK HOLES

摘要

The late-time evolution of massive Dirac fields in the backgrounds of brane-world black holes is investigated. We find that the dumping exponent depends on both the multiple number of the wave mode and the mass of the Dirac fields, but almost does not depend on the parameter Gamma of the brane-world black holes. We also find that the decay rate of the asymptotic late-time tail is t(-5/6). Our results show that the decay of massive Dirac hairs on brane-world black holes has the same behavior as that of the Schwarzschild black hole.
