Dynamical torsion as the microscopic origin of the neutrino seesaw

Research output: Contribution to journal › Article › peer-review

Abstract

It is assumed, that there are two scales in quantum gravity. Metric fluctuates at the scales of the order of the Planck mass. The second scale M_T is related to the fluctuations of torsion. We suppose, that it may be as low as M_T∼1 TeV. Due to the non-minimal coupling to torsion, the attractive interaction between the fermions appear. The non-minimal coupling admits the appearance of different coupling constants for different fermions. This opens the possibility that the interaction with torsion gives the Majorana masses for the right-handed neutrinos (that are assumed to be of the order of M_T). We suppose, that the Dirac masses for the neutrino are all close to the mass of electron. This gives the light neutrino masses ≤0.25 eV. In addition, the model predicts the appearance of Majorons that may contribute to the dark matter as well as to the invisible decay of the 125 GeV Higgs boson.
