$B ˉ_{s} \to f_{0} (980)$ form factors and the width effect from light-cone sum rules

Shan Cheng, Jian-Ming Shen

In this paper we calculate the $B ˉ_{s} \to f_{0} (980)$ form factors from light-cone sum rules with $B$ 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 $B \to π π$ form factors

Shan Cheng

We suggest to update the expansion coefficients of 2 $π$ DAs with the distribution amplitudes of light mesons evaluated from lattice QCD, with which we revisit $\overline{B}^0 \to π^…
