Abstract: (World Scientific)

We report an experimental determination of the isospin of Λc/Σc(2765)+ using 980 fb−1 data in the e+e− annihilation around s=10.6 GeV collected by the Belle detector located at the KEKB collider. The isospin partners are searched for in the Σc(2455)++/0π0 channels, and no evidence was obtained. Thus the isospin is determined to be zero, and the particle is established to be a Λc.

In this paper, the notation Σc(2765) is used only in the discussions of isospin partners of Σc(2765)+ and Λc(2765)+ or Λc(2765)+/Σc(2765)+ is used in the other cases. The choice of Λc(2765)+ is conventional and is consistent with the conclusion of the paper
