Description

Study of the processes e+e- →J/ψDD and D()+- D-+ by Belle is updated, where a new charmonium(-like) state X(3860) is observed with a significance of 6.5σ using full amplitude analysis in J/ψDD, and the first angular analysis is performed in D()+- D-+. We present the measurement of the absolute branching fractions of B+→Xcc K+ and B+→D()0 π+ decays. Here, Xcc denotes ηc, J/ψ, χc0, χc1, ηc(2S), ψ(2S), ψ(3770), X(3872), and X(3915). We also perform first search for hidden-strangeness penta-quark decay Ps+→φp in the Cabibbo-suppressed decay Λc→φpπ0. All the results presented here exploit the full data set of Belle.
