Measurement of neutrino and antineutrino neutral-current quasielastic-like interactions on oxygen by detecting nuclear de-excitation -rays
K. Abe, R. Akutsu, A. Ali +330
Neutrino- and antineutrino-oxygen neutral-current quasielastic-like interactions are measured at Super-Kamiokande using nuclear de-excitation -rays to identify signal-like inter…
Search for Electron Antineutrino Appearance in a Long-baseline Muon Antineutrino Beam
K. Abe, R. Akutsu, A. Ali +341
Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of…
Constraint on the Matter-Antimatter Symmetry-Violating Phase in Neutrino Oscillations
K. Abe, R. Akutsu, A. Ali +332
The current laws of physics do not explain the observed imbalance of matter and antimatter in the universe. Sakharov proposed that an explanation would require the violation of CP…
Sensitivity of Super-Kamiokande with Gadolinium to Low Energy Anti-neutrinos from Pre-supernova Emission
C. Simpson, K. Abe, C. Bronner +186
Supernova detection is a major objective of the Super-Kamiokande (SK) experiment. In the next stage of SK (SK-Gd), gadolinium (Gd) sulfate will be added to the detector, which will…
Measurement of the muon neutrino charged-current single production on hydrocarbon using the T2K off-axis near detector ND280
