Nucleon Pole Terms in Proton Decay

摘要

It is shown that nucleon pole terms can increase the proton decay rate by factors of 2 to 10 from that obtained from two quark fusion. The range of values corresponds to the uncertainty in the proton wave function at the origin - fixing parameters of the wave function to fit other short distance phenomena favours the large enhancement factors. This effect decreases the predicted lifetime in the minimal SU(5) model to the point where it is impossible to reconcile with recent limits on the lifetime. (Atomindex citation 15:008080)
