Description
The Very Special Relativity Electroweak Standard Model (VSR EW SM) is a theory with
SU(2)_L×U(1)_R symmetry, with the same number of leptons and gauge fields as in the usual Weinberg-Salam (WS) model.
No new particles are introduced. The model is renormalizable and unitarity is preserved. However,
photons obtain mass and the massive bosons obtain different masses for different polarizations. Besides,
neutrino masses are generated. A VSR invariant term will produce neutrino oscillations and new processes
are allowed. In particular, we compute the rate of the decays µ->e+photon. All these processes, which
are forbidden in the Electroweak Standard Model, put stringent bounds on the parameters of our model
and measure the violation of Lorentz invariance. Violations of Lorentz invariance have been predicted
by several theories of Quantum Gravity. It is a remarkable possibility that the low energy effects of
Lorentz violation induced by Quantum Gravity could be contained in the non-local terms of the VSR
EW SM.
