N2 - The baryon-to-lepton transition operators of grand unified theories could act as strong sources of meson fields, with the resulting field configurations, as computed classically, being kinematically forbidden. The consequent barrier penetration factors may suppress the proton decay rate by an order of magnitude below bounds obtained in previous calculations. This means that SU(5) remains barely compptible with limits on the decay p → e+π0. We obtain τ/Beπ 1 ̌032yr.
