First measurement of the charged current (nu)over-bar(mu) double differential cross section on a water target without pions in the final state
Physical Review Letters American Physical Society 102:1 (2020) 12007
Abstract:
This paper reports the first differential measurement of the charged-current νμ interaction cross section on water with no pions in the final state. The unfolded flux-averaged measurement using the T2K off-axis near detector is given in double-differential bins of μ+ momentum and angle. The integrated cross section in a restricted phase space is σ =(1.11 ± 0.18)×10−38 cm2 per water molecule. Comparisons with several nuclear models are also presented.Search for $hep$ solar neutrinos and the diffuse supernova neutrino background using all three phases of the Sudbury Neutrino Observatory

Simultaneous measurement of the muon neutrino charged-current cross section on oxygen and carbon without pions in the final state at T2K
PHYSICAL REVIEW D American Physical Society (APS) 101:11 (2020) ARTN 112004
Abstract:
© 2020 authors. Published by the American Physical Society. This paper reports the first simultaneous measurement of the double differential muon neutrino charged-current cross section on oxygen and carbon without pions in the final state as a function of the outgoing muon kinematics, made at the ND280 off-axis near detector of the T2K experiment. The ratio of the oxygen and carbon cross sections is also provided to help validate various models' ability to extrapolate between carbon and oxygen nuclear targets, as is required in T2K oscillation analyses. The data are taken using a neutrino beam with an energy spectrum peaked at 0.6 GeV. The extracted measurement is compared with the prediction from different Monte Carlo neutrino-nucleus interaction event generators, showing particular model separation for very forward-going muons. Overall, of the models tested, the result is best described using local Fermi gas descriptions of the nuclear ground state with RPA suppression.First combined measurement of the muon neutrino and antineutrino charged-current cross section without pions in the final state at T2K
