Postdoc Clarence Wret and Professor Kevin McFarland have been collaborating with colleagues from Fermilab, Los Alamos, and the University of Kentucky to study the effects of electromagnetic radiative corrections on neutrino interactions. The work has recently resulted in one long and one short paper which are currently in journal review.
One main conclusion from the work is that it appears that radiative corrections, while different in electron neutrino and muon neutrino reactions, don’t change the predicted cross-section ratio in such a way as to violate current assumptions. However, some of the neutrino energy going to additional energetic photons may require corrections to some oscillation analyses.
