Query: Decay Rates and Probability Estimates for Massive Dirac Particles in the
  Kerr-Newman Black Hole Geometry   The Cauchy problem is considered for the massive Dirac equation in the
non-extreme Kerr-Newman geometry, for smooth initial data with compact support
outside the event horizon and bounded angular momentum. We prove that the Dirac
wave function decays in L^\infty_loc at least at the rate t^{-5/6}. For generic
initial data, this rate of decay is sharp. We derive a formula for the
probability p that the Dirac particle escapes to infinity. For various
conditions on the initial data, we show that p=0,1 or 0<p<1. The proofs are
based on a refined analysis of the Dirac propagator constructed in
gr-qc/0005088.
