Strong Λ π Phase Shifts for CP Violation in Weak Ξ → Λ π Decay ⋆
Strong interaction Λπ phase shifts relevant for the weak nonleptonic decay Ξ → Λπ are calculated using baryon chiral perturbation theory. We find in leading order that the S-wave phase shift vanishes and the J = 1 2 P-wave phase shift is −1.7o. The small phase shifts imply that CP violation in this decay will be difficult to observe. Our results follow from chiral SU(2)L × SU(2)R symmetry. ⋆ Wo...

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...
متن کامل→ Σ π , Λ π and related strong coupling constant Zhi -
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...
