B DECAYS TO OPEN AND HIDDEN CHARM AT BELLE

摘要

The recent Belle collaboration measurements of B decays to open and hidden charm are discussed. Color-suppressed decay branching fractions are measured with an improved accuracy. The branching fractions of the B~0 → D_s~+K~- and B~0 → D_s~- π~+ decays, measured with improved accuracy, and B~0 → D_(sJ)~+K~- and B~0 → D_(sJ)~-π~+ decays, measured for the first time, are compared. The two-body invariant masses of the three-body B~0 → D~((*)~0)π~+π~- and B~0 → J/Ψ π~+ π~- decays are studied.
