Observation of Λ + c → Λ 0 K + , Λ + c → Σ 0 K + and Λ + c → Σ + K + π − decays
We present measurements of the Cabibbo-suppressed decays Λc → Λ 0K+ and Λc → Σ 0K+ (both first observations), Λc → Σ +K+π− (seen with large statistics for the first time), Λc → pK +K− and Λc → pφ (measured with improved accuracy). Improved branching ratio measurements for the decays Λc → Σ +K+K− and Λc → Σ +φ, which are attributed to W-exchange diagrams, are shown. We also present the first evi...

In this article, we calculate the strong coupling constant g among the decuplet baryons, the octet baryons and the pseudoscalar mesons in the heavy baryon chiral perturbation theory with the light-cone QCD sum rules, and study the strong decays Σ∗ → Λπ,Σπ. The numerical value of the strong coupling constant g is consistent with our previous calculation, the central values lead to small SU(3) br...

متن کاملOn the polarization properties of the charmed baryon Λ + c in the Λ + c → p + K − + π + + π 0 decay
The polarization properties of the charmed Λc baryon are investigated in weak non–leptonic four–body Λc → p+K−+π++π0 decay. The probability of this decay and the angular distribution of the probability are calculated in the effective quark model with chiral U(3)×U(3) symmetry incorporating Heavy Quark Effective theory (HQET) and the extended Nambu–Jona–Lasinio model with a linear realization of...
متن کاملThe contribution of Σ ∗ → Λ π to measured Λ polarization †
Calculations of the polarization of Λ and ¯ Λ particles after fragmentation of a polarized quark produced in processes like Z-decay and deep inelas-tic polarized lepton scattering must include Λ and ¯ Λ produced as decay products of Σ 0 and Σ * as well as those produced directly. These decay contributions are significant and not feasibly included in theoretical calculations based on QCD without...
