Probing Non-leptonic Two-body Decays of Bc meson

الأصل · EN

Rates and CP asymmetries of the non-leptonic two-body decay of Bc are calculated based on the low energy effective Hamiltonian. We concentrate on such b quark decays of the processes with 0- and 1- S-wave particles and/or 0+ and 1+ P-wave particles in the final states. The Salpeter method, which is the relativistic instantaneous approximation of the original Bethe-Salpeter equation, is used to derive hadron transition matrix elements. Based on the calculation, it is found that the best decay channels to observe CP violation are Bc-→ ηc +D-(D*⁻₀), which need about 10⁷ Bc events in experiment. Decays to ηc +D*⁻(Dₛ-), hc+D-(D*⁻)(D*⁻₀), J/Ψ+D*⁻ are also hopeful channels.
