Abstract

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.
