A photon and a graviton are both certainly devoid of mass and charge.
Therefore a massive black hole can certainly Hawking radiate either.
Is the intensity of photon radiation and graviton radiation by a black hole exactly equal, or different at some specific proportion due to different properties of electromagnetic and gravitational fields?
When can a black hole Hawking radiate a neutrino-antineutrino pair?
Are neutrino-antineutrino pairs Hawking radiated at a flavour eigenstate (at some average mass), or at a mass eigenstate?
There are observed square of mass differences with the two higher eigenstates. But is there a nonzero lower bound to the lower mass eigenstate of neutrino?
If the lower mass eigenstate of neutrino has mass which is zero or nonzero but small compared to the mass of photons and gravitons emitted by black hole, what would be the power emitted as neutrino-antineutrino pairs compared to the power emitted as photons?
And can a black hole have colour?
Black hole has no hair. Only mass, angular momentum and electric charge.
Colour is not a listed legal hair of a black hole.
A gluon is supposed to have no mass. Even a small gluon mass would be supposed to disturb some observed symmetries (which?).
If a gluon has no mass and a black hole no colour, what can stop a black hole from Hawking radiating a gluon? Because of no hair, the black hole has no colour to colour confine the colourful gluon!
