## Main Question or Discussion Point

First question:

Since a neutral Higgs boson is its own anti-particle, and has zero spin, it appears to have zero for all quantum numbers (in the standard model). This is what one would expect as well for the smallest neutral blackhole with no angular momentum.

What "new" quantum numbers does a candidate quantum gravity theory, like String Theory, suggest which would distinguish between a Higgs and neutral non-spinning blackhole?

Second question:

Are there any other candidate quantum gravity theories which also include matter at this point? (ie. are there other theories I could ask the first question of as well?)

Third question:

Does string theory predict a particle which by its quantum numbers would be considered to be a blackhole, yet is too light to be confined in a classical event horizon? Basically, a 'black hole' so light it is naked purely do to quantum mechanics? (Is there a term for this? That would help me in searches for references.)

I realize that a lot of this may not have definitive answers yet (especially the last one due to almost necessary vagueness), but I know there are a lot of intellegent people here working with string theory and I would very much appreciate your candid opinions and even educated speculation (please qualify it though, so I know it is educated speculation and not direct answers).
