Nucleon decay in the deuteron

We calculate the lifetime of deuteron from dimension-six quark operators that violate baryon number by one unit. construct an effective field theory for $|\Delta B|=1$ interactions give rise to nucleon and $\Delta B=1$ decay in a systematic expansion. show up including next-to-leading order rate is given sum rates free proton neutron. The first nuclear correction expected contribute at few-percent level comes with undetermined low-energy constant. discuss its relation earlier potential-model calculations.
