“…[39][40][41][42]. In the recent works, the K π contributions to the decay channels B → ψ K π [43] and B → P K π [44], with ψ = (J/ψ, ψ(2S)) and P = (K , π), were analyzed by employing the perturbative QCD (PQCD) factorization approach [45][46][47][48]. In addition, phenomenological studies of the processesB 0 → D 0 π + π − andB 0 s → D 0 K + π − based on results of the chiral unitary approach has been performed in Ref.…”

“…While these three-body decay processes are known to be dominated by the low energy scalar, vector and tensor resonant states, which could be handled in the quasi-two-body framework by neglecting the three-body and rescattering effects [63][64][65][66][67]. In the quasi-two-body region of the phase space, the three final states are quasi-aligned in the rest frame of the B meson and two of them almost collimate to each other, the related processes can be denoted as B → h 1 R → h 1 h 2 h 3 where h 1 represents the bachelor particle and the h 2 h 3 pair proceeds by the intermediate state R. In our previous works, the S-, P-and D-wave ππ and K π resonance contributions to a series of charmed or charmless three-body B (s) meson decays have been studied in [43,44,66,[68][69][70][71][72][73][74][75][76][77] within the PQCD approach by introducing two-meson distribution amplitudes [78][79][80][81][82][83][84]. The consistency of the theoretical studies and experimental results indicates the PQCD factorization approach are applicable to the three-body and quasi-two-body hadronic B meson decays.…”

Quasi-two-body decays $$B \rightarrow D K^*(892) \rightarrow D K \pi $$ in the perturbative QCD approach

We study the quasi-two-body decays B → DK * (892) → DK π by employing the perturbative QCD approach. The two-meson distribution amplitudes P-wave K π are adopted to describe the final state interactions of the kaon-pion pair in the resonance region. The resonance line shape for the P-wave K π component K * (892) in the timelike form factor F K π (s) is parameterized by the relativistic Breit-Wigner function. For most considered decay modes, the theoretical predictions for their branching ratios are consistent with currently available experimental measurements within errors. We also disscuss some ratios of the branching fractions of the concerned decay processes. More precise data from LHCb and Belle-II are expected to test our predictions.

“…The S-wave kaon-pion DAs for the resonance K Ã 0 ð1430Þ 0 have been studied in Ref. [63], and we will further investigate the dependence of the branching ratios in different scalar scenarios, as proposed in Refs. [64][65][66][67].…”

In this work, we analyze the three-body B ðsÞ → η c ð1S; 2SÞKπ decays within the framework of the perturbative QCD approach (PQCD) under the quasi-two-body approximation, where the kaon-pion invariant mass spectra are dominated by the K Ã 0 ð1430Þ 0 , K Ã 0 ð1950Þ 0 , K Ã ð892Þ 0 , K Ã ð1410Þ 0 , K Ã ð1680Þ 0 , and K Ã 2 ð1430Þ 0 resonances. The time-like form factors are adopted to parametrize the corresponding S, P, D-wave kaon-pion distribution amplitudes for the concerned decay modes, which describe the final-state interactions between the kaon and pion in the resonant region. The Kπ S-wave component at low Kπ mass is described by the LASS line shape, while the time-like form factors of other resonances are modeled by the relativistic Breit-Wigner function. We find the following main points: (a) the PQCD predictions of the branching ratios for most considered B → η c ð1SÞðK Ã0 →ÞK þ π − decays agree well with the currently available data within errors; (b) for BðB 0 → η c ðK Ã 0 ð1430Þ →ÞK þ π − Þ and BðB 0 → η c K þ π − ðNRÞÞ (where NR means nonresonant), our predictions of the branching ratios are a bit smaller than the measured ones; and (c) the PQCD results for the D-wave contributions considered in this work can be tested once precise data from the future LHCb and Belle-II experiments become available.

“…The perturbative QCD (pQCD) approach [28,29] is one of the recently developed theoretical tools based on QCD to deal with various exclusive processes [30]. In our previous papers [31,32], the S-wave ππðKπÞ resonant contributions are studied in the B → J=ψππðKπÞ decays as well as the ψð2SÞ counterparts. The related scalar resonance candidates include f 0 ð500Þ, f 0 ð980Þ, f 0 ð1500Þ, f 0 ð1790Þ, K Ã 0 ð1430Þ, and so on.…”

We present an analysis of two isovector scalar resonant contributions to the B decays into charmonia plus KK or πη pair in the perturbative QCD approach. The Flatté model for the a 0 ð980Þ resonance and the Breit Wigner formula for the a 0 ð1450Þ resonance are adopted to parametrize the timelike form factors in the dimeson distribution amplitudes, which capture the important final state interactions in these processes. The predicted distribution in the K þ K − invariant mass as well as its integrated branching ratio for the a 0 ð980Þ resonance in the B 0 → J=ψK þ K − mode agree well with the current available experimental data. The obtained branching ratio of the quasi-two-body decay B 0 → J=ψa 0 ð980Þð→π 0 ηÞ can reach the order of 10 −6 , letting the corresponding measurement appear feasible. For the a 0 ð1450Þ component, our results could be tested by further experiments in the LHCb and Belle II. We also discuss some theoretical uncertainties in detail in our calculation.
