Black Hole's 1/N Hair
hep-th 2012-03 conditional novelty 6.0 of 10

Inside a graviton-condensate model of black holes, global charge is not destroyed but survives as hair of relative strength B/N, so continuous global symmetries can coexist with black holes.
The minimal seesaw and leptogenesis models
hep-ph 2020-08 accept novelty 3.0 of 10

A comprehensive review of the two-right-handed-neutrino seesaw and its leptogenesis, organizing parametrizations, texture zeros, flavor symmetries and CP-violation predictions against current neutrino oscillation data.

9 arXiv papers cite this in 12 sentences

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON

On the one hand, switching off such a tiny mass term does allow for lepton flavor conservation in the classical regime of an SM-like system if non-perturbative quantum effects are not taken into account [ref] , and hence its presence seems not to be unnatural.

It has been argued in the past [ref] that any theory of quantum gravity will not allow B-L to be a symmetry of nature and thus could provide neutrinos with their mass.
