Description

KOTO (step-I) is the first experiment with the designed sensitivity of $O({10}^{-11})$ to probe for new physics through the rare $K_L^0\to {\pi }^0\nu \overline{\nu }$ decay. In 2018-2019, there were critical changes in the detector and the data acquisition system that further improved the research potential of KOTO. One of the significant changes in the detector was the dual-sided readout system of the CsI calorimeter to measure shower depth. This change not just suppressed the neutron background of the $K_L^0\to {\pi }^0\nu \overline{\nu }$ analysis, but potentially enabled KOTO to perform other rare-decay searches. Another change along with the detector was the newly designed trigger system, which opened up the bandwidth of data-collection for diverse research topics. This talk will cover the status and prospect of the analysis program in KOTO step-I.
