Quasi-two-body decays Bc→D(s)[ρ(770),ρ(1450),ρ(1700)→]ππ in the perturbative QCD factorization approach
In this paper, we studied the quasi-two-body Bc→D(s)[ρ(770),ρ(1450),ρ(1700)→]ππ decays by employing the perturbative QCD (PQCD) factorization approach. The two-pion distribution amplitudes Φππ are applied to include the final-state interactions between the pion pair, while the time-like form factors...
