Constraints ofξ-moments computed using QCD sum rules on pion distribution amplitude models
《Chinese Physics C》2023年第1期125-134,共10页钟涛 朱志豪 付海冰 
Supported in part by the National Natural Science Foundation of China(12265009,12265010,12175025,12147102);the Project of Guizhou Provincial Department of Science and Technology(ZK[2021]024);the Project of Guizhou Provincial Department of Education(KY[2021]030);the Chongqing Graduate Research and Innovation Foundation(ydstd1912)。
To date,the behavior of the pionic leading-twist distribution amplitude(DA)φ2;π(x,μ)-which is a universal physical quantity and is introduced into high-energy processes involving pions based on the factorization th...

Improved analysis of the rare decay processes of Λ_(b)
《Communications in Theoretical Physics》2021年第10期114-124,共11页Ren-hao Deng Yong-lu Liu Ming-qiu Huang 
It is noted that in the new Particle Data Group(PDG) version the rare decays of the Λ_(b) baryon have been revised with more accuracy. The new results show that most of the existing theoretical results on the process...

B→A transitions in the light-cone QCD sum rules with the chiral current
《Chinese Physics C》2012年第11期1046-1054,共9页孙艳军 王志刚 黄涛 
Supported by National Natural Science Foundation of China(10735080,10805082,10675098,11075053);the Fundamental Research Funds for the Central Universities
In this article, we calculate the form-factors of the transitions B → a1（1260）, b1（1235） in the leading-order approximation using the light-cone QCD sum rules. In calculations, we choose the chiral current to int...

Analysis of the Vertexes ΣQ([I])*QK* and ([1])'Q*Σ*QK* within Light-Cone QCD Sum Rules
《Chinese Physics Letters》2012年第2期51-54,共4页YOU Fu-Yi WANG Zhi-Gang WAN Shao-Long 
Supported by the National Natural Science Foundation of China under Grant No 10675108.
We parameterize the vertexes ΣQ([1])*QK* and ([1])'QΣ*QK* with three tensor structures due to Lorentz invariance,and calculate the corresponding three coupling constants within light-cone QCD sum rules.We then obtai...

Analysis of the coupling constants g_(a_0ηπ~0) and g_(a_0η’ π~0) with light-cone QCD sum rules
《Chinese Physics C》2010年第1期7-15,共9页王志刚 
Supported by NSFC (10775051);Program for New Century Excellent Talents in University (NCET-07-0282)
In this article, we take the point of view that the light scalar meson a0（980） is a conventional qqstate, and calculate the coupling constants ga0ηπ0 and ga0ηπ0 with the light-cone QCD sum rules. The central val...

supported by the National Natural Science Foundation of China (Grant No 10775051);the Program for New Century Excellent Talents in University of China (Grant No NCET-07-0282)
In this article, we calculate the contribution from the nonfactorizable soft hadronic matrix element to the decay B^0→Xc1π^0 with the light-cone quantum chromo-dynamic （QCD） sum rules. The numerical results show t...

Supported by National Natural Science Foundation of China under Grant No.10775051;Program for New Century Excellent Talents in Universities under Grant No.NCET-07-0282
In this article, we assume that the （0^＋,1^＋） strange-bottom mesons are the conventional bs mesons, and calculate the electromagnetic coupling constants d, g1, g2, and g3 using the light-cone QGD sum rules. Then w...

Analysis of Vertex D^＊D^＊ρ with Light-Cone QCD Sum Rules
《Chinese Physics Letters》2008年第2期444-446,共3页王志刚 王志斌 
Supported by the National Natural Science Foundation of China under Grant Nos 10405009 and 10775051, and the Programme for New Century Excellent Talents in University under Grant No NCET-07-0282, and the Key Programme of North China Electric Power University.
We analyse the vertex D^＊D^＊ρ with the light-cone QCD sum rules. The strong coupling constant gD^＊D^＊ρ is an important parameter in evaluating the charmonium absorption cross sections in searching for the quark-...
