Kaon decays at KLOE-2

Abstract

I review kaon decays. I introduce the flavor problem and possible solutions. Very rare kaon decays like K→πνν¯ are very important to this purpose: we study also K→πl+l−,K→ππee where chiral dynamics is important to disentangle short distance effects. We have also studied lepton flavor (universality) violation in rare kaon decays and the Bardeen Buras Gerard approach to describe the K±→π±l+l− form factor.
