Abstract
In this research the weak decay of B + c decays to the K+K−π+ final state, which is being observed by LHCb collaboration for the first time, is calculated in the quasi-two-body decays which takes the B 0 s , χc0 and D0 resonances and weak annihilation nonresonant contributions into account. In this process, the B + c meson decays first into B 0 s π+, χc0π+ and D0π+ intermediate states, and then the B 0 s , χc0 and D0 resonances decay into K+K− components, which undergo final state interaction. The mode of the B + c → D0(→K−π+)K+ is also associated with the calculation, in this mode the intermediate resonance D0 decays to the K−π+ final mesons. The resonances B 0 s , χc0 and D0 effects in the B + c → B 0 s (→K+K−)π+, B + c → χc0(→K+K−)π+ and B + c → D0(→K+K−)π+, D0(→ K−π+)K+ decays are described in terms of the quasi-two-body modes. There is a weak annihilation nonresonant contribution in which B + c decays to the K+K−π+ directly, so the point-like 3-body matrix element \( \left\langle {K}^{+}{K}^{-}{\pi}^{+}\left|u\overline{d}\right|0\right\rangle \) is also considered. The decay mode of the \( {B}_c^{+}\to {\overline{K}}^{\ast 0}(892){K}^{+} \) is contributed to the annihilation contribution. The branching ratios of quasi-two-body decays expand in the range of (2.12 ± 0.61) × 10−6 to (7.56 ± 1.71) × 10−6.
