“…Adding measurements on δ CP from few years of T2K exposure will allow to slightly increase the separation between the two options in different portions of δ CP range [7]. Conversely, if MH should be known sometimes in future, T2K would greatly improve its significance on δ CP [8].…”

The ordering of the neutrino mass eigenstates, also addressed as Mass Hierarchy (MH), is one of the most relevant issues in neutrino physics, currently under investigation by many proposals and experiments. In this short note focus will be given to the different ways to determine MH from neutrino oscillation data in the near future. A pragmatic strategy is suggested and two recent new methods of analysis are recalled. Statistical issues and concerns are also addressed, envisaging the necessity of more accurate studies and analyses. PRESENTED AT NuPhys2017, Prospects in Neutrino Physics

Muon beam monitoring is indispensable for indirectly monitoring accelerator-produced neutrino beams in real time. Though Si photodiodes and ionization chambers have been successfully used as muon monitors at the T2K experiment, sensors that are more radiation tolerant are desired for future operation. We have investigated the electron-multiplier tube (EMT) as a new sensor for muon monitoring. Secondary electrons produced by the passage of muons at dynodes are multiplied in the tube and produce signal. Two prototype detectors were installed at the T2K muon monitor location, and various EMT properties were studied based on in situ data taken with the T2K muon beam. The signal size is as expected based on calculation, and the EMTs show a sufficiently fast time response for bunch-by-bunch beam monitoring. The spill-by-spill intensity resolution is 0.4%, better than the required value (1%). Signal linearity within ±1% is achieved at proton beam powers up to 460 kW (with +250 kA focusing horn operation). A gradual signal decrease was observed during the initial exposure, due to the stabilization of dynode materials, before the response became stable within ±1%. This work demonstrates that EMTs are a good candidate for future muon monitoring at T2K, and may also have other more general applications.

Thank to the stable operation at intense beam power, T2K data with neutrino-mode operation almost doubled in one year. A number of critical improvements to the oscillation analysis have been introduced and resulted in an unprecedented level of sensitivity in searching for CP violation in the neutrino sector. T2K firstly reports that the CP-conserving values of parameter δCP in the PMNS mixing matrix fall out of its 2σ C.L. measured range.
