Unraveling the Enigma of Neutrino Mass: A Novel Random Matrix Theory Approach

Collider experiments at CERN have placed new constraints on the seesaw mechanism, a popular model for the origin of neutrino mass. The CMS Collaboration searched for a hypothetical heavy neutrino that could be tied to neutrino mass generation but found no evidence of its existence. These results provide important constraints on variants of the seesaw mechanism and pave the way for future studies combining searches for lepton number violation and sterile neutrinos. While neutrino oscillation experiments have made progress in determining oscillation parameters, the underlying mechanism of neutrino mass generation remains elusive.
