Correlating Bq0→μ+μ− and KL→π0νν¯ decays with four generations

The Bs→μ+μ− mode has finally been observed, albeit at rate 1.2σ below Standard Model (SM) value, while the rarer Bd0→μ+μ− decay has central value close to 4 times SM expectation but with only 2.2σ significance. The measurement of CP violating phase ϕs has finally reached SM sensitivity. Concurrent w...
