Preparation of the Hyper-Kamiokande experiment – a unique observatory for rare events in the Universe

Title: Preparation of the Hyper-Kamiokande experiment – a unique observatory for rare events in the Universe

Supervisor: Boris Popov

Team: Asymétrie Matière-Antimatière ; group HK

Description :

The Hyper-Kamiokande (HK) experiment will be built in Japan by
an international collaboration. The detector will hold 260000 tonnes
of ultra-pure water – eight times larger compared to
the existing Super-Kamiokande (SK). The enormous size of the will
enable it to detect unprecedented numbers of neutrinos produced
by various sources — including the Sun, supernovae, cosmic rays
and beams artificially produced by an existing particle accelerator.
In addition to catching neutrinos, it will monitor the water for
a possible spontaneous decay of protons in atomic nuclei, which,
if observed, would be a revolutionary discovery.
A team of physicists from LPNHE-Paris plans to contribute to the HK
detector construction via a precise time distribution and
synchronization system and to the physics analysis via data
calibration and reconstruction.
We will also take part in the upgrade of ND280, the near detector
in the present T2K experiment which will also serve as near
detector for the HK experiment. And we contribute to the
hadroproduction measurements done with the NA61/SHINE experiment
at CERN to reduce the systematic uncertainties on the accelerator
neutrino flux for HK.
The PhD candidate will contribute to the characterization and
installation of the clock distribution system, but also to the
analysis of the NA61/SHINE data, which will be specifically
taken for HK. He/she will then include them in the simulation
of the neutrino beam to endup with an evaluation of the sensitivity
improvement of the HK experiment in the measurement of the
oscillation parameters, including the CP-violation phase.
