The model-independent method based on the triangle ideology is implemented to extract the CKM-matrix angle γ in the decays of doubly heavy baryons containing the charmed and beauty quarks. We analyze a color structure of diagrams and conditions to reconstruct two reference-triangles by tagging the flavor and CP eigenstates of D 0 ↔ ¯ D 0 mesons in the fixed exclusive channels. The characteristi...

CP-violating signals in weak Ξ → πΛ decay require the knowledge of πΛ Sand P-wave scattering phases at m Ξ center-of-mass energy. We have calculated these phases in baryon chiral perturbation theory with the ground-state Σ in s and u channels and 3 2 + Σ(1385) in the u channel. We do not treat the baryons as heavy. We find δ S = 1.2 • and δ P = −1.7 • with the central value of the strong coupli...
