Light neutrino masses from gravitational condensation: the
In this work we demonstrate that non-zero neutrino masses can be generated
from gravitational interactions. We solve the Schwinger-Dyson equations to find
a non-trivial vacuum thereby determining the scale of the neutrino condensate
and the number of new particle degrees of freedom required for gravitationally
induced dynamical chiral symmetry breaking. We show for minimal beyond the
Standard Model particle content, the scale of the condensation occurs close to
the Planck scale.
