Description
The goal of the K0TO experiment at J-Parc is to discover and measure
the rate of the rare decay of the neutral KL into pi0 nu nubar .
This flavor changing neutral current decay
proceeds through second-order weak interactions.
Other, as yet undiscovered particles, which can mediate the decay could
provide an enhancement to the branching ratio,
which in the Standard Model predicted to be about (2.8 +/- 0.4)*10**(-11).
The experiment is expected to observe 100 events
at the Standard Model branching ratio for a 10% measurement.
The experiment is a follow-up to E391 at KEK with a completely redesigned
beamline, a new CsI calorimeter with increased granularity and
reduced shower leakage,
and a new readout electronics, trigger and data acquisition system.
K0TO is scheduled for a first engineering run at the end of 2010
and the first physics run in 2011.
