Description
In the last years, experiments with neutrinos from accelerators have been instrumental for our knowledge of neutrino oscillations.
Long baseline neutrino experiments (T2K and NOVA), combining a high-intensity neutrino beam, sophisticated near detectors and massive far detectors, have established a non zero theta13 angle and measured with precision the theta23 angle and the Dm*2_32 mass difference.
After a description of the experimental setup, recent results from these long baseline experiments will be showed with emphasis on the T2K experiment.
T2K decided to launch a major upgrade of its near detector that has been recently installed, featuring a novel highly segmented Fine Grained Detector and two new TPCs. Moreover, the accelerator complex has been upgraded to reach a proton beam power on target of 800 kW.
I will briefly mention the future of the field : new experiments (DUNE and HyperKamiokande) are in construction to complete the picture with measurements of the CP violation phase delta and the mass ordering.
The challenges facing this program will be presented, in particular the uncertainties in the neutrino nucleus cross-sections.
