$K^{0}_{L}\rightarrow \pi^{0} \nu \bar{\nu}$ at KOTO

Understand

The KOTO experiment aims to discover the rare decay $K^{0}_{L}\rightarrow \pi^{0} \nu \bar{\nu}$ at J-PARC.

• This mode breaks the CP symmetry directly and is highly suppressed in the Standard Model.
• Thus the mode is sensitive to new physics, in particular to the models related to CP violation.
• We performed the first physics run in May 2013.
