Tomography of high-twist proton structure through $e p$ elastic scattering

Ji-Xin Yu, Shan Cheng, Jia-Jie Han +2

We present the first high-twist study of the proton form factors $F_{1, 2} (Q^{2})$ in $e p$ elastic scattering based on the perturbative QCD $k_{T}$ factorization, $Q^{2}$ being momentum t…

$C P$ 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 $I ¨ ^{-}$ ,…

Study of $B_{c} \to I ¨ _{c J} (P, V)$ decays in the improved perturbative QCD formalism

Xin Liu, Hsiang-nan Li, Zhen-Jun Xiao

Motivated by the recent LHCb measurements of the ratios between the branching ratios (BRs), $R_{I ¨ _{c 2} / J / I ¨ } \equiv BR (B_{c}^{+} \to I ¨ _{c 2} I ¨ ^{+}) / BR (B_{c}^{+} \to J / I ¨ I ¨ ^{+})$ …

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…
