The helicity form factors within the QCD light-cone sum rules
Wei Cheng, Xing-Gang Wu, Rui-Yu Zhou +1
We study the helicity form factors (HFFs) by applying the light-cone sum rules up to twist-4 accuracy. The HFF has some advantages in comparison to the conventionally cal…
The semileptonic and radiative decays within the light-cone sum rules
Hai-Bing Fu, Long Zeng, Rong Lü +2
The measured branching ratio of the meson semileptonic decay , which is based on the CLEO data taken at the peak of resonance, di…
The Ratio and the -meson Distribution Amplitude
Tao Zhong, Yi Zhang, Xing-Gang Wu +2
In this paper, we calculate the transition form factors (TFFs) within the light-cone sum rules (LCSR) and predict the ratio . More accurate -meson distr…
The asymmetries of the decay and the search of new physics beyond the Standard Model
Hai-Bing Fu, Xing-Gang Wu, Wei Cheng +2
In this paper, we compute the forward-backward asymmetry and the isospin asymmetry of the decay. The transition form factors (TFFs) are key componen…
The longitudinal leading-twist distribution amplitude of meson within background field theory
Hai-Bing Fu, Long Zeng, Wei Cheng +2
We make a detailed study on the meson longitudinal leading-twist distribution amplitude by using the QCD sum rules within the background field theory. By keepi…
