dc.descriptionWe have derived new upper limits on several products (two at a time) of lepton number violating $λ'$-type couplings from the consideration of $ΔS = 2$ and $ΔB = 2$ box graphs. Each box contains one scalar lepton and one W-boson or one charged-Higgs-boson as internal lines. Most of these bounds are more stringent than previously obtained. Some of these product couplings drive $K_L$ (and some other $B_d$) decays to two charged leptons at enhanced rates. Some of them can explain the rare $K^+ \to π^+ ν\barν$ event recently observed at BNL.
