Galactic Dark Matter Population as the Source of Neutrino Masses

Understand

We propose that neutrino masses can be zero $in ~vacuo$ and may be generated by the local distribution of dark matter through a feeble long range scalar force.

• We discuss potential phenomenological constraints and implications of this framework.
• Our model typically implies that the relic neutrino background left over from the Big Bang is mostly absent in our Galactic neighborhood.
• Hence, a positive detection signal from future proposed experiments, such as PTOLEMY, could in principle falsify our scenario.
