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…
Charmless two-body meson decays in perturbative QCD factorization approach
Jian Chai, Shan Cheng, Yao-hui Ju +3
The perturbative QCD (PQCD) approach based on factorization has made a great achievement for the QCD calculation of the hadronic B decays. Regulating the endpoint divergence…
helicity form factors and the exclusive weak decays
Shan Cheng, Yao-hui Ju, Qin Qin +1
The decay width of the meson is dominated by the electromagnetic mode , and it is thus the longest-lived charged vector meson. In light of this poi…
Probing isovector scalar mesons in the charmless three-body decays
Jian Chai, Shan Cheng, Ai-Jun Ma
We propose to study the multiparticle configurations of isovector scalar mesons, saying and , in the charmless three-body decays by considering the width…
The role of and their contributions in decays
Jian Chai, Shan Cheng, Wen-Fei Wang
We demonstrate the roles of and their contributions in the quasi-two-body decays () in the perturbative QCD…
The PQCD approach towards to next-to-leading order: a short review
Shan Cheng, Zhen-jun Xiao
In this short review we elaborate the significance of resummation in factorization theorem, and summarize the recent progresses in the calculations of the next-to-leading ord…
