particle physics - Can colliders detect B violation?



I think there is some theoretical uncertainty whether high-energy collisions can violate B. It is known that at high temperature (higher than the Higgs scale) you violate B by SU(2) instantons. But in a situation where you have a very energetic 2-particle collision at arbitrarily high energy, I am not sure if there is a non-negligible probability of producing a Baryon violating configuration. I don't know of any calculation of B violation expected in accelerators, although there might be an argument that it should be very close to zero, because of the non-thermalizing nature of 2-particle collisions.


Can you detect standard model B violation in colliders? Does LHC look for rare B violating events, or would such rare events be indistinguishable from a proton or neutron escaping undetected?
