Description
At the quantum level, an interaction of a neutrino with a graviton may
trigger the collapse of the neutrino flavor eigenstate to a neutrino mass
eigenstate. I will present that such an essentially quantum gravity effect
may have strong consequences for neutrino oscillation phenomena in
astrophysics due to the relatively large scattering cross section of
relativistic neutrinos off massive sources of gravitational fields (the case
of gravitational Bethe-Heitler scattering). This results in a new technique
for the indirect detection of gravitons by measuring the flavor composition
of astrophysical neutrinos.
