Determination of -meson distribution amplitudes from transition form factors
Dong-Hao Li, Cai-Dian Lü, Ulf-G. MeiÃner +1
Recent work on , and form factors from lattice QCD and light-cone sum rules has made it possible to constrain the inverse moment of the -meson ligh…
Final-state rescattering in decays
Zhu-Ding Duan, Xiao Huang, Dong-Hao Li +3
The LHCb Collaboration has recently reported the first observation of the decay , along with measurements of the branching fractions for both $\bar…
Next-to-Next-to-Leading-Order Corrections to the Form Factors from Light-Cone Sum Rules
Yong-Kang Huang, Dong-Hao Li, Cai-Dian Lü +2
By incorporating the available leading-power results at and next-to-leading-power corrections at tree level, we improve the precision of the theoretical predict…
Precision calculations of form factors from SCET sum rules beyond leading-power contributions
Jing Gao, Ulf-G. MeiÃner, Yue-Long Shen +1
We construct light-cone sum rules (LCSR) for the form factors in the large recoil region using vacuum-to--meson correlation functions, and systematically calculate su…
