Abstract

AbstractLHCb Collaboration studied the resonant structure of $$B_s\rightarrow \overline{D}^0K^-\pi ^+$$ B s D ¯ 0 K - π + decays using the Dalitz plot analysis technique, based on a data sample corresponding to an integrated luminosity of $$3.0\textrm{fb}^{-1}$$ 3.0 fb - 1 of pp collision. The $$K^-\pi ^+$$ K - π + components have been analyzed in the amplitude model, where the decay amplitude is modeled to be the resonant contributions with respect to the intermediate resonances $$K^*(892)$$ K ( 892 ) , $$K_0^*(1430)$$ K 0 ( 1430 ) and $$K_2^*(1430)$$ K 2 ( 1430 ) . Motivated by the experimental results, we investigate the CKM-favored quasi-two-body $$B \rightarrow \overline{D}^0K\pi $$ B D ¯ 0 K π decays in the framework of the perturbative QCD (PQCD) approach. We calculate the the branching fractions by introducing the appropriate wave functions of $$K\pi $$ K π pair. Our results are in agreement well the available data, and others can be tested in LHCb and Belle-II experiments. Using the narrow-width-approximation, we also extract the branching fractions of the corresponding two-body $$B\rightarrow {\overline{D}} R$$ B D ¯ R decays, which agree to the previous theoretical calculations and the experimental data within the errors. There are no CP asymmetries in these decays in the standard model, because these decays are all governed by only the tree operators.
