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…
The pion light-cone distribution amplitude from the pion electromagnetic form factor
Shan Cheng, Alexander Khodjamirian, Aleksey V. Rusov
We suggest to probe the pion light-cone distribution amplitude, applying a dispersion relation for the pion electromagnetic form factor. Instead of the standard dispersion relation…
form factors and the width effect from light-cone sum rules
Shan Cheng, Jian-Ming Shen
In this paper we calculate the form factors from light-cone sum rules with meson DAs. With adopting the quark-antiquark configuration of light scalar m…
Pion and Kaon form factors in the perturbative QCD approach
Shan Cheng
We present the most accurate calculation for the pion and kaon electromagnetic form factors in the framework of perturbative QCD, where the power corrections up to twist-4 of the m…
Dipion light-cone distribution amplitudes and form factors
Shan Cheng
We suggest to update the expansion coefficients of 2DAs with the distribution amplitudes of light mesons evaluated from lattice QCD, with which we revisit $\overline{B}^0 \to π^…
