Electroweak corrections to K+→π+νν and KL→π0νν — •Emmanuel Stamou — Techniche Universität München, Boltzmannstraße 2, 85748 Garching
The rare decays K+→π+νν and KL→π0νν are strongly suppressed in the standard model. The sensitivity to high energy phenomena makes these processes prime candidates to test the standard model and discriminate various scenarios of new physics. Recent theoretical progress together with the smallness of hadronic uncertainties allows for a precise theory prediction. However, one of the dominant uncertainty arising from the two-loop electroweak corrections from top quark contributions is still unknown. In this talk I shall discuss the calculation of these corrections.
