Description
We present a scenario where the smallness of neutrino masses is related to a global symmetry violation by quantum gravitational effects. We propose a setup that leads to axion particles which decay into neutrinos. This setup could be probed via cosmological measurements and may help explain the Hubble parameter tension. Depending on the details, the scenario could provide axion dark matter candidates.
