The photon-neutrino interaction in non-commutative gauge field theory and astrophysical bounds

arXiv:hep-ph/0212292 · doi:10.1140/epjc/s2004-01874-5

Abstract

In this letter we propose a possible mechanism of left- and right-handed neutrino couplings to photons, which arises quite naturally in non-commutative gauge field theory. We estimate the predicted additional energy-loss in stars induced by space-time non-commutativity. The usual requirement that any new energy-loss mechanism in globular stellar clusters should not excessively exceed the standard neutrino losses implies a scale of non-commutative gauge theory above the scale of weak interactions.
