Opening up baryon number violating operators

Baryon number violation is our most sensitive probe of physics beyond the

Standard Model. Its realization through heavy new particles can be conveniently encoded

in higher-dimensional operators that allow for a model-agnostic analysis. The unparalleled

sensitivity of nuclear decays to baryon number violation makes it possible to probe effective

operators of very high mass dimension, far beyond the commonly discussed dimension-six

operators. To facilitate studies of this ginormous and scarcely explored testable operator

landscape we provide the exhaustive set of baryon-number-violating operators up to mass

dimension 15, which corresponds roughly to the border of sensitivity, as well as their

explicit UV completions. In addition to the known Standard Model fields we also include

right-handed neutrinos in our operators.
