## Hadron production measurements with the NA61/SHINE spectrometer at CERN for precise prediction of (anti)neutrino fluxes in ongoing and future long baseline accelerator neutrino experiments

Title: Hadron production measurements with the NA61/SHINE spectrometer at CERN for precise prediction of (anti)neutrino fluxes in ongoing and future long baseline accelerator neutrino experiments

Supervisor: Boris Popov

Co-supervisor: Jacques Dumarchez

Team: Asymétrie Matière-Antimatière ; group T2K

Description :

The LPNHE neutrino group participates in the NA61/SHINE hadron production
experiment at CERN which continues to collect data for precise (anti)neutrino
flux predictions in future long baseline neutrino experiments, including
the on-going T2K experiment as well as the next generation Hyper-Kamiokande
(HK) project in Japan.
The group is heavily involved in the T2K neutrino oscillation experiment
which is finalizing the upgrade towards the second phase of the experiment,
T2K-II, in order to improve constraints on the CP violation in the lepton
sector.
The next generation long-baseline neutrino oscillation experiment —
Hyper-Kamiokande — will be built in Japan in the coming years.
The detector will be exposed to the same (anti)neutrino beam produced
at the J-PARC accelerator.
Refined predictions of (anti)neutrino fluxes in T2K-II and HK using
a new NA61/SHINE data taking campaign planned in 2021/2022 with a T2K replica
target and their integration into the oscillation analysis are crucial
for precise measurements of neutrino oscillation parameters and for
the discovery of CP violation in the lepton sector.
The successful candidate will participate in the collection and analysis of
these NA61/SHINE data as well as in the integration of the corresponding
results in the T2K-II oscillation analysis and in the calculation of expected
HK sensitivity.
