Polarization fractions and helicity-dependent CP asymmetries in $B_{(s)} \to I ¨ I ¨ , I ¨ K^{}$ and $K^{} K^{*}$ decays

Jian Chai, Shan Cheng, Feng-Qing Hu +3

In this paper, we present a phenomenological analysis of $B_{(s)} \to I ¨ I ¨ , I ¨ K^{*}$ and $K^{*} K^{*}$ decays using state-of-the-art perturbative QCD (pQCD) calculations. Our st…

$B_{c}$ meson decays into $S$ -wave charmonium plus light meson pairs in the perturbative QCD approach

Jia-Ying Wang, Jing Jiang, Yu-Jie Liu +4

In this work, we explore the $P$ -wave resonance contributions to the three-body charmonium decays of $B_{c} \to I^¨ (V \to) P_{1} P_{2}$ using the perturbative QCD formalism at leading order,…

$C P$ violation in two-body hadronic $I^_{b}$ decays in the PQCD approach

Jia-Jie Han, Ji-Xin Yu, Ya Li +4

We systematically investigate the $C P$ -averaged branching ratios and $C P$ violations (CPVs) for the two-body hadronic decays $I^_{b} \to p h$ , where $h$ runs through the mesons $I ¨ ^{-}$ ,…

Establishing CP Violation in $b$ -Baryon Decays

Jia-Jie Han, Ji-Xin Yu, Ya Li +4

It is a long-standing puzzle why the {\it CP} violation (CPV) in the baryon system has not yet been definitively established as in the meson one. We demonstrate that individual par…

Improved global determination of two-meson distribution amplitudes from multi-body $B$ decays

Da-Cheng Yan, Hsiang-nan Li, Zhou Rui +2

We improve the perturbative QCD (PQCD) formalism for multi-body charmless hadronic $B$ meson decays, such as $B \to V P_{3} \to P_{1} P_{2} P_{3}$ , by resolving the possible discrepancy in para…
