On Oct. 11, Pavel Fileviez Perez, of the Department of Physics, published an article in Physical Review D titled “Low Scale Seesaw with Local Lepton Number.”
The origin of the charged fermion and gauge bosons masses in the Standard Model of particle physics is well understood. After the discovery of the Higgs boson at the Large Hadron Collider, researchers know that spontaneous symmetry breaking plays a fundamental role in nature. It is well known that the Standard Model does not provide a mechanism to generate neutrino masses and one needs to look for a more complete theory.
In this publication, Prof. Pavel Fileviez Perez and his graduate student Hridoy Debnath propose a new theory for Majorana neutrino masses that predicts a dark matter candidate. Using the cosmological bounds on the dark matter relic density they point out the possibility to find an upper bound on the symmetry breaking scale in the multi-TeV region. This new theory could be tested at the Large Hadron Collider through the observation of exotic signatures related to the origin of neutrino masses. This theory could be tested in the near future and we could know what is the mechanism to explain neutrino masses in nature.
