Particle physics - accelerators experiments

The main goal of the experiment E246 at KEK (National Laboratory for High Energy Physics, Japan) is a search of T-violation in the decay К⁺—>m⁺p⁰ν. The experiment is sensitive to new physics beyond the Standard Model, in particular for testing the CP-violation mechanism through a Higgs exchange.

The main goal of the E949 experiment at BNL (Brookhaven National Laboratory, USA) is to measure a rare, flavor changing neutral current decay К⁺—>p⁺νν with a sensitivity of about 10^-11, an order of magnitude below the Standard Model prediction. This will result in a determination of the CKM matrix element |V_td| to better than 25%.
