Title: Gold-plated Mode of CP-Violation in Decays of B_c Meson from QCD Sum Rules
Title: 从QCD求和规则看B_c介子衰变中的金镀层CP破坏模式
Abstract: The model-independent method based on the triangle ideology is implemented to extract the CKM-matrix angle gamma in the decays of doubly heavy long-lived meson B_c. We analyze a color structure of diagrams and conditions to reconstruct two reference-triangles by tagging the flavor and CP eigenstates of D^0 meson in the fixed exclusive channels. The characteristic branching ratios are evaluated in the framework of QCD sum rules.
