Photon-neutrino interaction in theta-exact covariant NCGFT: Phenomenology & Quantum properties


Abstract:
Photon-neutrino interactions arise quite naturally in noncommutative field theories. Such couplings are absent in ordinary field theory and imply experimental lower bounds on the energy scale theta ~ 1/Lambda^2_NC of noncommutativity. Using non-perturbative methods and a Seiberg-Witten map based covariant approach to noncommutative gauge theory, we obtain theta-exact expressions for the interactions, thereby eliminating previous restrictions to low-energy phenomena. We discuss implications for plasmon decay, neutrino charge radii, big bang nucleosynthesis and ultrahigh energy cosmic rays. Our results behave reasonably throughout all interaction energy scales, thus facilitating further phenomenological applications. Finally we discus Quantum propertis of our model, i.e. neutrino self-energy, and model independent connection of NCGFT to Holography with respect to UV/IR mixing in terms of IR/NC/Pl/UV cutoffs.
