“…Stimulated by the abundant experimental measurements, the theoretical explorations have been carried out in the recent years. Many three-body nonleptonic decays of heavy mesons have been studied in detail in QCD factorization [17][18][19][20][21][22][23], PQCD approach [24][25][26][27][28][29][30][31][32][33] and other theoretical methods [34][35][36][37].…”

LHCb Collaboration studied the resonant structure of B s → D 0 K − π + decays using the Dalitz plot analysis technique, based on a data sample corresponding to an integrated luminosity of 3.0fb −1 of pp collision. The 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 * 0 (1430) and K * 2 (1430). Motivated by the experimental results, we investigate the color-favored quasitwo-body B → D 0 Kπ decays in the framework of the perturbative QCD (PQCD) approach. We calculate the the branching fractions by introducing the appropriate wave functions of Kπ 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 → DR 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.

LHCb 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.

“…In past decades, more and more analysis of three-body decays have been performed by the BaBar, Belle, CLEO and LHCb, and the branching fractions and CP violations have been measured with high precision. Motivated by the accumulated experimental results, many theoretical studies of various three-body B hadronic decays have been performed in different frameworks, such as approaches based on the symmetry principles [5][6][7][8][9], the QCD factorization (QCDF) [10][11][12][13][14][15][16][17][18][19][20], the perturbative QCD approach (PQCD) [1,[21][22][23][24][25][26][27][28], and other theoretical methods [29][30][31].…”

Three-body B decays not only significantly broaden the study of B meson decay mechanisms, but also provide information of resonant particles. Because of complicate dynamics, it is very hard for us to study the whole phase space in a specific approach. In this review, we takeas examples and show the application of the perturbative QCD (PQCD) approach in studying the quasi-two-body B decays, where two particles move collinearly with large energy and the bachelor one recoils back. To describe the dynamics of two collinear particles, the (S, P and D)-wave functions of kaon-pair with different waves are introduced. By keeping the transverse momenta, all possible diagrams including the hard spectator diagrams and annihilation ones can be calculated in PQCD approach. Most results are well consistent with the current measurements from BaBar, Belle and LHCb experiments. Moreover, under the narrowwidth approximation we can extract the branching fractions of the two-body decays involving the resonant states, and also predict the branching fractions of the corresponding quasi-two-body decays B → K(R →)π + π − . All prediction are expected to be tested in the ongoing LHCb and Belle-II experiments.
