 Forbidden Kaon and Pion Decays in NA62 / Moulson, Matthew (INFN, Frascati) NA62, an experiment at the CERN SPS to measure the branching ratio for the decay K+ -> pi+ nu nu-bar with ~10% precision, will observe ~10^13 K+ decays in its fiducial volume, and will thus also be able to carry out a rich program to search for forbidden K+ and pi0 decays, including in particular K+ decays that violate the conservation of lepton flavor and/or number.

 The Muon Collider as a $H/A$ factory / Eichten, Estia (Fermilab) ; Martin, Adam (CERN ; Notre Dame U.) We show that a muon collider is ideally suited for the study of heavy H/A scalars, cousins of the Higgs boson found in two-Higgs doublet models and required in supersymmetric models.
