Long range neutrino forces and the lower bound on neutrino mass

TL;DR

The paper discusses how neutrino seas in stellar objects block long-range neutrino forces, eliminating the need for a lower bound on neutrino mass and challenging previous claims.

Contribution

It demonstrates that neutrino seas cause effective blocking of long-range neutrino forces, removing the necessity of a lower neutrino mass bound.

Findings

Neutrino seas lead to effective blocking of long-range forces.

This blocking resolves the stellar self-energy problem.

No lower bound on neutrino mass is required, contrary to previous claims.

Abstract

Stellar objects (including our Sun, other stars of main sequence, white dwarfs, neutron stars etc.) contain strongly degenerate low energy sea of neutrinos (in neutron stars) or antineutrinos. The presence of this sea leads due to Pauli principle and thermal effects to effective blocking of the long-range neutrino forces. This blocking can resolve the problem of the unphysically large value of the self-energy of stars stipulated by many body long-range neutrino interactions. As a consequence no lower bound on the neutrino mass is inferred, in contrast with the statement by Fischbach.
