7 Jun 2019 | | Abstract: | We analyze neutrino mixing and oscillations within the framework of extended
theories of gravity. In particular, by relying on the covariant reformulation
of Pontecorvo’s formalism, we evaluate the oscillation probability of neutrinos
propagating in several static spacetimes described by gravitational actions
quadratic in the curvature invariants. We show that neutrino oscillation phase
is sensitive to the violation of the strong equivalence principle. This
connection may be in principle explained via the appearance of the
Eddington-Robertson-Schiff parameter in the neutrino Hamiltonian. The above
studies are then specialized to different extended models in order both to
quantify such a violation and to understand how the characteristic free
parameters of the theories could affect the standard result. The possibility to
fix new bounds on such parameters and to constrain extended theories of gravity
is also discussed. | | Source: | arXiv, 1906.3131 | | Services: | Forum | Review | PDF | Favorites | |
