Solar neutrinos: Radiative corrections in neutrino-electron scattering experiments

Radiative corrections to the electron recoil-energy spectra and to total cross sections are computed for neutrino-electron scattering by solid neutrinos. Radiative corrections change monotonically the electron recoil spectrum for incident ${}_{}{}^8{}_{}{}^{}\mathrm{B}$ neutrinos, with the relative probability of observing recoil electrons being reduced by about 4% at the highest electron energies. For p-p and ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ neutrinos, the recoil spectra are not affected significantly. Total cross sections for solar neutrino-electron scattering are reduced by about 2% compared to previously computed values. We also calculate the recoil spectra from ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ and ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$ neutrinos including radiative corrections.
