Neutrino mass and spontaneous parity nonconservation

RN Mohapatra, G Senjanović - Physical Review Letters, 1980 - APS
In weak-interaction models with spontaneous parity nonconservation, based on the gauge
group SU (2) L⊗ SU (2) R⊗ U (1), we obtain the following formula for the neutrino mass: m ν …

Neutrino masses and mixings in gauge models with spontaneous parity violation

RN Mohapatra, G Senjanović - Physical Review D, 1981 - APS
Unified electroweak gauge theories based on the gauge group SU (2) L× SU (2) R× U (1) B−
L, in which the breakdown of parity invariance is spontaneous, lead most naturally to a …

A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case
