Experiment COMET at J-PARC
Participating Countries and International Organizations:
Belarus, Czech Republic, Georgia, Germany, United Kingdom, France, Russia, Japan.
Scientific Programme:
Te goal of the COMET experiment at the accelerator of J-PARC is the search for a neutrinoless conversion of a muon into an electron µ - N e - N,
in which the lepton number in the charged sector does not conserve. Within the SM, modified taking into account the neutrino oscillations, the expected rate is less than 10 -50
and so any observation of conversion would be a clear signal of a new physics beyond the SM. A measurement at the level 10 -17 for conversion, which is the COMET goal,
is a factor of 10000 better than that of the current experimental limit B(µ -+ Auµ e - + Au) < 7·10 -13 from SINDRUM-II at PSI.
Expected main results in 2018:
- R&D on thin-wall straw-tubes for experiment COMET. Development, production and tests of the straw detector and electromagnetic calorimeter prototypes with a beam.
- Calibration of LYSO crystals.
