Duane A. Dicus, Wayne W. Repko
TL;DR
This paper estimates the decay rate of the Z boson into a neutrino-antineutrino pair and two photons using an effective interaction model, providing an approximate branching ratio.
Contribution
It introduces a method to estimate the Z -> nu nubar gamma gamma decay width based on effective neutrino-photon interactions, which is a novel approach.
Findings
Calculated an approximate decay width for Z -> nu nubar gamma gamma
Provided an estimate of the branching ratio for this rare decay
Enhanced understanding of neutrino-photon interactions in Z decay processes
Abstract
The effective interaction for two neutrino, two photon coupling is used to find an approximate width for the decay of the Z boson into the nu nubar gamma gamma final state.
