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

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

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

$B \to K K ˉ (π η) h$ decays in the presence of isovector scalar resonances $a_{0} (980, 1450)$

Si-Yang Wang, Zhi-Qing Zhang, Zhi-Jie Sun +2

Different from the previous treatment in a two-body framework, we introduce the dimeson distribution amplitudes (DAs) to describe the strong dynamics between the S-wave resonances…

Determination of pion distribution amplitudes from the electromagnetic form factor with the data-driven dispersion relation

Jian Chai, Shan Cheng, Jun Hua

We study the pion electromagnetic form factor in the modulus squared dispersion relation, and do the model independent extraction of the most important nonperturbative parameters i…

Hochschild homology, trace map and $ζ$ -cycles

Alain Connes, Caterina Consani

In this paper we consider two spectral realizations of the zeros of the Riemann zeta function. The first one involves all non-trivial (non-real) zeros and is expressed in terms of…

Charmless two-body $B$ meson decays in perturbative QCD factorization approach

Jian Chai, Shan Cheng, Yao-hui Ju +3

The perturbative QCD (PQCD) approach based on $k_{T}$ factorization has made a great achievement for the QCD calculation of the hadronic B decays. Regulating the endpoint divergence…

Probing isovector scalar mesons in the charmless three-body $B$ decays

Jian Chai, Shan Cheng, Ai-Jun Ma

We propose to study the multiparticle configurations of isovector scalar mesons, saying $a_{0} (980)$ and $a_{0} (1450)$ , in the charmless three-body $B$ decays by considering the width…

The role of $D_{(s)}^{*}$ and their contributions in $B_{(s)} \to D_{(s)} h h^{'}$ decays

Jian Chai, Shan Cheng, Wen-Fei Wang

We demonstrate the roles of $D_{(s)}^{*}$ and their contributions in the quasi-two-body decays $B_{(s)} \to D_{(s)} h h^{'}$ ( $h, h^{'} = {π, K}$ ) in the perturbative QCD…

Contributions of $K_{0}^{} (1430)$ and $K_{0}^{} (1950)$ in the three-body decays $B \to K π h$

Wen-Fei Wang, Jian Chai, Ai-Jun Ma

We study the contributions of the resonant states $K_{0}^{*} (1430)$ and $K_{0}^{*} (1950)$ in the three-body decays $B \to K π h$ (with $h = π, K$ ) in the perturbative QCD approach. The cruc…

Virtual contributions from $D^{} (2007)^{0}$ and $D^{} (2010)^{\pm}$ in the $B \to D π h$ decays

Wen-Fei Wang, Jian Chai

We study the quasi-two-body decays $B \to D^{*} h \to D π h$ with $h = (π, K)$ in the perturbative QCD approach and focus on the virtual contributions from the off-shell $D^{*} (2007)^{0}$ …
