Study of intermidiate two-body decays in B0bar -> Sigma_c(2455)0 pbar pi+ decay at Belle

초록

We study the three-body decay B0bar -> Sigma_c(2455)0 pbar pi+ and observe a broad mass structure in the pbar pi+ mass system near 1.5GeV/c^2 which indicates an intermediate two-body decay B0bar -> Sigma_c(2455)0 Nbar0. This analysis is based on a data sample of 357 fb-1, accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e+e- collider.
