Subleading power corrections to decay in PQCD approach
Yue-Long Shen, Zhi-Tian Zou, Yan-Bing Wei
The leptonic radiative decay is of great importance in the determination of meson wave functions, and evaluating the form factors are the essential probl…
QCD calculations of form factors with higher-twist corrections
Cai-Dian Lü, Yue-Long Shen, Yu-Ming Wang +1
We update QCD calculations of form factors at large hadronic recoil by including the subleading-power corrections from the higher-twist -meson light-cone distributi…
Exclusive production of mesons in colliders
Yan-Bing Wei, Run-Hui Li, Dan Luo +2
Within the framework of the perturbative QCD approach, we calculate the time-like form factors and . We include relativistic corrections and QCD…
Radiative leptonic decay with subleading power corrections
M. Beneke, V. M. Braun, Yao Ji +1
We reconsider the QCD predictions for the radiative decay with an energetic photon in the final state by taking into account the power-suppressed…
