The Mu2e experiment will search for the CLFV conversion of muons into electrons in the field of an Al nucleus, planning to reach a single event sensitivity of about 3x10−17, four orders of magnitude beyond the current best limit.
The conversion electron has a monoenergetic signature at 105 MeV and will be identified by a high-resolution straw tracker and an electromagnetic calorimeter...

The MEG II experiment in a search of $\mu\to\mathrm{e}\gamma$ started taking physics data in 2021. A liquid xenon calorimeter with 4760 photosensors measures photon position, time, and energy of 52.8 MeV. The precise energy reconstruction to distinguish signal and background events requires the calibration of photosensors and an energy scale of the calorimeter. The energy resolution of 1.8%...

The MUon proton Scattering Experiment (MUSE) at the PiM1 beam line of the Paul Scherrer Institute is simultaneously measuring the elastic scattering of electrons and muons from a liquid hydrogen target to extract the charge radius of the proton with both positive and negative beam polarities. In addition to providing precise data for addressing the proton radius puzzle, by comparing the...

The T2K long-baseline neutrino oscillation experiment showed the strongest constraint on the CP violating phase that governs the matter/antimatter symmetry breaking in neutrino oscillation. For further improvement of the experimental sensitivity, T2K installed a novel high granular scintillator detector, called SuperFGD, to reduce systematics. It consists of about 2 millions of 1 cm$^3$...

The Belle II at SuperKEKB electron-positron collider is the new generation B-factory experiment and calorimetry plays an important role to detect neutral particles and reconstruct missing energy/momentum. The CsI(Tl) crystals with the PIN-Photodiode readout are inherited from Belle experiment and readout electronics and data acquisition system are replaced to cope with the high event rate...

SuperKEKB electron-positron collider utilizes continuous injection to get the world highest luminosity for the Belle II experiment. The injected bunch becomes the source of extra background for 10-20 ms duration and crosses the interaction point (IP) every 10 microsec. To reconstruct energy deposition and timing of the incident particle, the Belle II calorimeter uses the waveform sampling...
