Abstract
The rare processes \( {B}_c\to {D_{(s)}^{\left(*\right)}}_J\mu \overline{\mu} \), where D (*)(s) J stands for the final meson D * s0 (2317), D s1(2460, 2536), D * s2 (2573), D *0 (2400), D 1(2420, 2430) or D *2 (2460), are studied within the Standard Model. The hadronic matrix elements are evaluated in the Bethe-Salpeter approach and furthermore a discussion on the gauge-invariant condition of the annihilation hadronic currents is presented. Considering the penguin, box, annihilation, color-favored cascade and color-suppressed cascade contributions, the observables dBr/dQ 2, A LPL , A FB and P L are calculated.
