Dirac neutrinos and B-L breakingThe seesaw mechanism (and its variants) is compatible with Dirac neutrinos while DM stability comes from Diracness symmetry. Chuliá, Srivastava, Valle, Phys.Lett. B781 (2018) 122-128; Chuliá, Srivastava, Valle, Phys.Rev. D98 (2018) no.3, 035009
-Does new physics break B-L? If so, what is the breaking pattern?-A remnant subgroup of B-L that survives the spontaneous symmetry breaking can lead to Dirac neutrinos. Diracness can be easily related with DM stability.Chiral but anomaly free B-L charges can generate naturally small neutrino masses and DM stability ‘a la scotogenic’. Bonilla, Cepedello, Chuliá, Peinado, Srivastava, 1812.01599
