Constraints on neutrino masses coming from magnetic dipole moments in a two Higgs doublet model type I and II

In the framework of a two Higgs doublet model type I and type II, we calculate limits on neutrino masses for the different types of neutrinos, by using the experimental bounds on their magnetic dipole moments. This is carried out by analyzing diagrams of Cherenkov neutrino decays with a charged Higgs into the loop, coming from the two Higgs doublet model (2HDM). Such constraints are translated into allowed regions in the free parameters of the models, for each neutrino flavor. The analysis was performed by sweeping the charged Higgs mass between (100-900)GeV and taking into account the experimental constraints for $\tan\beta $ in the 2HDM type I and II, obtaining contributions close to the experimental thresholds for muon and tau neutrinos, while for electron neutrino the relevant contribution comes from standard model and keeps out of the reach of forthcoming experiments.
