Study of charmed baryons at Belle

Research output: Contribution to journalConference articlepeer-review

Abstract

We report measurements of the branching fractions of the decays Λ+c → Σ+ππ+, Λ+c → Σ0π+π0 and Λ+c → Σ+π0π0 relative to the reference channel Λ+c → pKπ+ [1]. The charmed-strange baryon Ξc(2930)0, decaying to KΛ+c , is observed for the first time in B → KΛ+c Λc decays. We also measure B(B → KΛ+c Λc ) with improved precision, and search for the charmonium-like state Y(4660) and its spin partner, Yη, in the Λ+c Λc invariant mass spectrum [2]. Decays of the |0c charmed baryon into hadronic final states were studied[3]. We present the results of a study of excited |c charmed baryons in the decay mode Ξ+c K [4].
