Gravitational coupling of neutrinos in a medium
نویسنده
چکیده
In a medium that contains electrons but not the other charged leptons, such as normal matter, the gravitational interactions of neutrinos are not the same for all the neutrino flavors. We calculate the leading order matter-induced corrections to the neutrino gravitational interactions in such a medium and consider some of their physical implications.

When neutrinos travel through a normal matter medium, the electron neutrinos couple differently to gravity compared to the other neutrinos, due to the presence of electrons in the medium and the absence of the other charged leptons. The matter-induced gravitational couplings of the neutrinos under such conditions are calculated and their contribution to the neutrino index of refraction in the p...
متن کاملMomentum-dependent contributions to the gravitational coupling of neutrinos in a medium
When neutrinos travel through a normal matter medium, the electron neutrinos couple differently to gravity compared to the other neutrinos, due to the presence of electrons in the medium and the absence of the other charged leptons. We calculate the momentum-dependent part of the matter-induced gravitational couplings of the neutrinos under such conditions, which arise at order g/M W , and dete...
متن کاملRadiative Corrections to Gravitational Coupling of Neutrinos and Neutrino Oscillations
It is well known that if the gravitational coupling of neutrino's is avour dependent then this can give rise to neutrino oscillations which can explain the solar and atmospheric neutrino anomalies. Once the universality of the gravitational coupling () i.e., the gravitational gauge invariance is violated at the tree level then there is no way of protecting from radiative corrections. We calcula...

In this talk I discuss neutrino oscillations due to possible nonuniversality of the gravitational coupling constants. It has been pointed out [1] [2] that a breakdown of the universality of the gravitational couplings to different neutrino flavors could lead to neutrino oscillations. In particular the authors of [2] studied the possibility in which the solar neutrinos can be used to test this k...
متن کاملSpin Flavor Oscillation of Neutrinos in Rotating Gravitational Fields and Their Effects on Pulsar Kicks
The origin of high velocities of pulsars is studied by considering the spin-flip conversion of neutrinos propagating in a gravitational field of a protoneutron star. For a rotating gravitational source (such as pulsars) with angular velocity , one finds that the spin connections (entering in the Dirac equation written in curved space time) induce an additional contribution to neutrino energy wh...
