Physics Graduate Student Symposium (PGSS) | Status on the Search for the Rare Kaon Decay, K_L→ π^0νν

The KOTO experiment at the J-PARC research facility in Tokai, Japan aims to observe and measure the rare decay of the neutral kaon, K_L→π^0νν. This decay has a very small Standard Model predicted branching ratio of 3 x 10^{-11} which is why it has never been experimentally observed. While this decay is extremely rare, it is one of the best decays for studying charge-parity violation, which can tell us about the matter and antimatter asymmetry that we see in the universe today. In this talk, I will explain the details of how KOTO searches for this rare decay and present new results from the collaboration published in January 2019 as well as preliminary results from the current analysis.
