Study of quasi-two-body B^{0}\rightarrow T(\pi\pi, K\bar{K},\pi\eta) decays in perturbative QCD approach

Autor: Mu, Lun-Lian, Yu, Xian-Qiao

In this study, we calculate the CP-averaged branching ratios and the direct CP-violating asymmetries of the three body decays B^{0}\rightarrow T(\pi\pi, K\bar{K},\pi\eta) in the perturbative QCD (PQCD) approach, where T denotes tensor mesons a_{2}(13

We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral $B$ mesons to $\Lambda^{0}$ and $\Omega^{(*)0}_c$ using 711~${\rm fb^{-1}}$ of data collected at the $\Upsilon(4S)$ resonance with

Contributions of the subprocess $K^*_0(1430) \to K\eta^{\prime}$ in the charmless three-body $B$ meson decays

Autor: Ma, Ai-Jun, Wang, Wen-Fei

Publikováno v: Phys. Rev. D 109, 056017 (2024)

We study the contributions for $K\eta^{\prime}$ pair originating from the scalar intermediate state $K_0^{*}(1430)$ in the three-body decays $B\to K\eta^{\prime} h$ ($h=\pi, K$) within the perturbative QCD approach. The contribution of $K^*_0(1430)\t
