The KOTO experiment at the J-PARC research facility in Tokai-mura, Japan aims to observe and measure the rare decay of the neutral kaon, KL → π0νν¯, in which a neutral kaon decays to a neutral pion and a neutrino antineutrino pair. This decay has a Standard Model predicted branching ratio of (3.00 ± 0.30) x 10^−11. While this decay is extremely rare, it is one of the best decays for studying charge-parity (CP) violation in the quark sector. Because the signal decay has such a low branching ratio, the data acquisition (DAQ) system for the KOTO experiment uses three levels of trigger cuts to selectively record events of interest and discard background events. The KOTO DAQ system is designed to have a highly optimized signal acceptance and background rejection due to the high trigger rate. This poster will focus on these details and how the triggers and DAQ system address the physics requirements of the detectors.
