The evanescence of rest masses and electric charge in black holes
  The classical Einstein-Standard Model system with conformally invariant coupling of the Higgs field to gravity is investigated in nearly Schwarzschild black holes. We show that, in the presence of Kantowski-Sachs symmetries, there is a finite critical value of the mean curvature such that on spacelike hypersurfaces with greater mean curvature the Higgs sector does not have any symmetry breaking vacuum state. Hence, according to the Standard Model of particle physics, the gauge and spinor fields do not have rest mass and electric charge. Therefore, particles falling into a nearly Schwarzschild black hole lose their mass and charge in the "reverse" Brout-Englert-Higgs mechanism.
