Simulating Modifications to the P 42 Beamline for the KLEVER Experiment

Studies of Very Rare Kaon Decays have the potential to search for new physics beyond the Standard Model by precision measurements. The branching ratio (BR) of K → πν?̅? is predicted precisely by the Standard Model. Measuring the BR of K → πνν and KL → π ν?̅? could verify predictions by the Standard Model or help support new physics beyond the Standard Model theories. These measurements are particularly associated with predictions made by the CKM matrix, which describes quark mixing angles. The K → πν?̅? search is very sensitive. Currently, it is being studied by the NA62 experiment at CERN, and in the future could be studied by the KLEVER experiment [1].
