Abstract

We present results of a detailed study of the three-body over(B, ̄)⁰ → Σ_c (2455)⁰ over(p, ̄) π⁺ decay. A significant enhancement of signal events is observed in the over(p, ̄) π⁺ invariant mass distribution near 1.5 GeV / c² that is consistent with the presence of an intermediate baryonic resonance over(N, ̄)⁰, where over(N, ̄)⁰ is the over(N, ̄) (1440)⁰ P₁₁ or over(N, ̄) (1535)⁰ S₁₁ state, or an admixture of the two states. We measure the product B (over(B, ̄)⁰ → Σ_c (2455)⁰ over(N, ̄)⁰) × B (over(N, ̄)⁰ → over(p, ̄) π⁺) = (0.80 ± 0.15 (stat .) ± 0.14 (syst .) ± 0.21) × 10^-4, where the last error is due to the uncertainty in B (Λ_c⁺ → p K^- π⁺). The significance of the signal is 6.1 standard deviations. This analysis is based on a data sample of 357 fb^-1, accumulated at the Υ{hooked} (4 S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺ e^- collider.

N2 - We present results of a detailed study of the three-body over(B, ̄)0 → Σc (2455)0 over(p, ̄) π+ decay. A significant enhancement of signal events is observed in the over(p, ̄) π+ invariant mass distribution near 1.5 GeV / c2 that is consistent with the presence of an intermediate baryonic resonance over(N, ̄)0, where over(N, ̄)0 is the over(N, ̄) (1440)0 P11 or over(N, ̄) (1535)0 S11 state, or an admixture of the two states. We measure the product B (over(B, ̄)0 → Σc (2455)0 over(N, ̄)0) × B (over(N, ̄)0 → over(p, ̄) π+) = (0.80 ± 0.15 (stat .) ± 0.14 (syst .) ± 0.21) × 10-4, where the last error is due to the uncertainty in B (Λc+ → p K- π+). The significance of the signal is 6.1 standard deviations. This analysis is based on a data sample of 357 fb-1, accumulated at the Υ{hooked} (4 S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider.
