Summary � The first evidence of B�τν has obtained by Belle @414fb-1 . � Successful operation of B factories have finally brought the B leptonic decays on the stage. � O(ab-1 ) data will bring B�μν and Bd�μμ for serious examination. � These enable us to explore New Physics, esp. in large tanβ region, together with other measurements; ΔmBS, Bs�μμ, B�Xsγ and also τ decays (τ�μη, τ�μγ). � O(10ab-1 � The first evidence of B�τν has obtained by Belle @414fb ) data will bring B�Kνν at horizon. -1 . � Successful operation of B factories have finally brought the B leptonic decays on the stage. � O(ab-1 ) data will bring B�μν and Bd�μμ for serious examination. � These enable us to explore New Physics, esp. in large tanβ region, together with other measurements; ΔmBS, Bs�μμ, B�Xsγ and also τ decays (τ�μη, τ�μγ). � O(10ab-1 (see talk by A.Weiler) ) data will bring B�Kνν at horizon. We need a Super B Factory ! ! � Super-KEKB aims at L=8x1035cm-2s-1 � Super-KEKB aims at L=8x10 , with tech. proven at KEKB. � A lot of activities for physics and detector studies. � HEP community in Japan is now discussing “Grand Lepton Collider” plan to accommodate both Super-KEKB and ILC. 35cm-2s-1 , with tech. proven at KEKB. � A lot of activities for physics and detector studies. � HEP community in Japan is now discussing “Grand Lepton Collider” plan to accommodate both Super-KEKB and ILC.
