-state twist-2 light-cone distribution amplitude moments within QCD sum rules and its implication in decays

Ya-Lin Song, Yin-Long Yang, Yan-Ting Yang +4

Based on longstanding puzzle for the structure of light scalar meson, it is meaningful to make a deep research for its property in different decay processes especially in the botto…

Non-perturbaitve effects for the isoscalar light vector -meson in charmed meson semileptonic decays

Yin-Long Yang, Fang-Ping Peng, Yan-Ting Yang +2

Motivated by the renewed attention from the recent BESIII experiment on the semileptonic decay , we investigate semileptonic decay

Probing the equivalence of chiral LCSRs in decays and extraction of

Xiu-Fen Wang, Hai-Jiang Tian, Yin-Long Yang +2

In the paper, we have carried out research on the decay process. We employ two different currents to study the transition form factors (TFFs) by using the light-c…

Searching the possibility of scalar state being a diquark structure via charmed meson semileptonic decays

Ya-Lin Song, Yin-Long Yang, Ye Cao +2

The internal structure of light scalar state has not been definitively determined, it may consist of multiple possible states. Among them, it has the possibility of bei…

Exploring the exclusive decay with light-cone sum rules

Yin-Long Yang, Ya-Lin Song, Fang-Ping Peng +3

In this paper, we calculate the Cabibbo-Kobayashi-Maskawa matrix element by the semileptonic decay . For the transition form factors (TFFs)

Footprint in fitting vector form factor and determination for -meson leading-twist LCDA

Sheng-Bo Wu, Hai-Jiang Tian, Yin-Long Yang +3

In this paper, we fit the vector transition form factor (TFF) by using the data measured by \textsl{BABAR} and Belle Collaborations within Monte Carlo (MC) method. Meanwhi…
