Abstract:
KOTO experiment at J-PARC aims to measure the rare KL→π0νν decay. This decay is a CP-violating process, and its theoretical branching ratio can be precisely calculated with only a few percent uncertainties in the standard model. Therefore, it offers a clean ground for probing new physics by looking for the decay amplitude deviations. KOTO plans to achieve this goal in the coming ten years, based on the J-PARC's beam-intensity upgrade in 2021, new detectors to manage background level, and a new DAQ system to tolerant the higher trigger rate. In this talk, I will recap the current analysis status, detector/DAQ upgrades, and the future plans of KOTO.
