Abstract

We present the selected recent charm results at Belle: (1) the CPCP asymmetries and branching fractions for the decays of charm mesons, i.e. D0π+πη,K+KηD^{0}\to\pi^{+}\pi^{-}\eta,\,K^{+}K^{-}\eta and D0ϕηD^{0}\to\phi\eta; Ds+K+π0,K+ηD_{s}^{+}\to K^{+}\pi^{0},\,K^{+}\eta and Ds+π+π0,π+ηD_{s}^{+}\to\pi^{+}\pi^{0},\,\pi^{+}\eta. (2) the branching fractions for the decays of charmed baryons, i.e. Λc+pπ0,pη\Lambda_{c}^{+}\to p\pi^{0},\,p\eta; Λc+Λπ+η,Σ0π+η\Lambda_{c}^{+}\to\Lambda\pi^{+}\eta,\,\Sigma^0\pi^{+}\eta and intermediate processes Λc+Λ(1670)π+,ηΣ(1385)+\Lambda_{c}^{+}\to\Lambda(1670)\pi^{+},\,\eta\Sigma(1385)^+; Ξc0ΛKˉ0,Σ0Kˉ0\Xi_c^0\to\Lambda\bar{K}^{*0},\,\Sigma^0\bar{K}^{*0} and Σ+K\Sigma^+K^{*-}. (3) properties of excited charmed baryons, i.e. search for electromagnetic transition Ξc(2790,2815)+,0Ξc+,0γ\Xi_c(2790,2815)^{+,0}\to\Xi_c^{+,0}\gamma; and determination of spin-parity of Ξc(2970)+\Xi_c(2970)^+.
