Spin-flavour conversion of neutrinos in loop quantum gravity

G Lambiase

Show affiliations


Loop quantum gravity theory incorporates a new scale length Script L which may induce a Lorentz invariance breakdown. This scale can be either a universal constant or fixed by the momentum of particles (Script L ~ p−1). Effects of the scale parameter Script L and helicity terms occurring in the dispersion relation of fermions are reviewed in the framework of spin-flip conversion of neutrino flavours.
