Properties of the leading-twist distribution amplitude and its effects to the decays
Dan-Dan Hu, Xing-Gang Wu, Hai-Bing Fu +3
The -mesons in the quark-flavor basis are mixtures of two mesonic states and . In th…
Twist-2 Distribution Amplitude and Transition Form Factors
Dong Huang, Tao Zhong, Hai-Bing Fu +3
Based on the scenario that the is viewed as the ground state of or , we study the leading-twist distribution amplitude (DA) $…
helicity form factors and the decays
Wei Cheng, Yi Zhang, Long Zeng +2
In this paper, we calculate the helicity form factors (HFFs) up to twist-4 accuracy by using the light-cone sum rules (LCSR) approach. After extrapolating those HFFs t…
The -meson leading-twist distribution amplitude within the QCD sum rules and its application to the transition form factor
Yi Zhang, Tao Zhong, Hai-Bing Fu +2
We make a detailed study on the meson leading-twist LCDA by using the QCD sum rules within the framework of the background field theory. To improve the precision,…
