Title: 
Rare Kaon Decays on the Lattice
Abstract: 
Rare kaon decays present many interesting phenomenological opportunities. The decays of a kaon to a pion and a lepton/antilepton pair, which proceed via a FCNC, are useful for studying CP violation and probing for New Physics. The decay of a kaon to a pion and a charged lepton/antilepton pair however is dominated by long distance effects, making it an excellent candidate for a lattice calculation. I will discuss the methodology of calculating the amplitude of the long distance contributions to this decay using lattice QCD and present the numerical results of some exploratory studies.
