Abstract

New results on charmonium-like states measured by the Belle experiment at the KEKB asymmetric e⁺e^- collider are presented, in particular (a) Search for the Z_c pair production in $ϒ (1 S), ϒ (2 S)$ $\Upsilon (1{\rm{S}}),\,\Upsilon (2S)$ decays and in e⁺e^- $\sqrt{s}$ $\sqrt s$ of 10.52, 10.58, and 10.867 GeV. (b) Measurement of the absolute branching fractions of $B^{+} \to X_{c \bar{c}} K^{+}$ ${B^ + } \to {X_{c\overline c }}{K^ + }$ decays. (c) Observation of Ξ_c(2930)⁰ in the updated measurement of $B^{-} \to K^{-} Λ_{c} {\bar{Λ}}_{\bar{c}} .$ ${B^ - } \to {K^ - }{\Lambda _c}{\overline \Lambda _{\overline c }}.$ (d) Angular analysis of $e^{+} e^{-} \to D^{(*) \pm} D^{* \mp}$ ${e^ + }{e^ - } \to {D^{(*) \pm }}{D^{* \mp }}$ process near the open charm threshold using initial state radiation.
