Q:
What would the behavior of an Anti-Proton be in our environment? Would it pass threw an electron cloud and annihilate? I'm particularly curious if it would behave like a Cooper pair.

A:

Hi James,

Its life would be short and sweet, going out with a bang.   It's possible it could annihilate with an electron, giving rise to a neutrino and a few mesons, but that's pretty rare.   More probably it would bounce around until it found a proton, either free or inside a nucleus, and annihilate into mesons.

Cooper pairs involve two electrons bound together at low temperatures.  An anti-proton doesn't fit into this catagory.
