Measurement of neutrino and antineutrino neutral-current quasielasticlike interactions on oxygen by detecting nuclear deexcitation γ rays

Abstract:

Neutrino- and antineutrino-oxygen neutral-current quasielasticlike interactions are measured at SuperKamiokande using nuclear deexcitation γ rays to identify signal-like interactions in data from a 14.94ð16.35Þ × 1020 protons-on-target exposure of the T2K neutrino (antineutrino) beam. The measured flux-averaged cross sections on oxygen nuclei are hσν-NCQEi ¼ 1.70 0.17ðstat:Þ þ0.51 −0.38 ðsyst:Þ × 10−38 cm2=oxygen with a fluxaveraged energy of 0.82 GeV and hσν¯-NCQEi ¼ 0.98 0.16ðstat:Þ þ0.26...
