Rare Kaon Decays: a unique probe for New Physics

Abstract:

Kaon mesons had a key role in establishing the experimental foundations of the Standard Model of Particle Physics and still continue to be at the intersection of discovery and innovation in high-energy physics. With unmatched capacity to investigate new physics at the multi-TeV scale, rare kaon decays stand among the most sensitive probe in the quest for physics beyond the Standard Model but are also an experimentally challenging playground pushing the development of cutting-edge technology.  In this seminar the role of rare kaon decays in the present physics landscape will be discussed with particular emphasis on the experimental status, recent results and prospects of the experiments NA62 and LHCb at CERN and KOTO at JPARC.
