QED radiative corrections for accelerator neutrinos.

ABSTRACT: Neutrino oscillation experiments at accelerator energies aim to establish charge-parity violation in the neutrino sector by measuring the energy-dependent rate of ν_e appearance and ν_μ disappearance in a ν_μ beam. These experiments can precisely measure ν_μ cross sections at near detectors, but ν_e cross sections are poorly constrained and require theoretical inputs. In particular, quantum electrodynamics radiative corrections are different for electrons and muons. These corrections are proportional to the small quantum electrodynamics coupling α ≈ 1/137; however, the large separation of scales between the neutrino energy and the proton mass (~GeV), and the electron mass and soft-photon detection thresholds (~MeV) introduces large logarith
