Systematic classification of two-loop d = 4 Dirac neutrino mass models and the Diracness-dark matter stability connection
Abstract We provide a complete systematic classification of all two-loop realizations of the dimension four operator for Dirac neutrino masses. Our classification is multi-layered, starting first with a classification in terms of all possible distinct two loop topologies. Then we discuss the possibl...
