Effects from hadronic structure of photon on B→φγ and B_(s)→(ρ^(0),ω)γ decays
《Chinese Physics C》2023年第2期46-54,共9页李运 邹芝田 沈月龙 李营 
Supported in part by the Open Project of Shaanxi Collaborative Innovation Center of Industrial Auxiliary Chemistry & Technology (XTKF-2020-01);the Nation-al Science Foundation of China (11705159,11975195);the Natural Science Foundation of Shandong province (ZR2019JQ04,ZR2022ZD26,ZR2020MA093);the Project of Shandong Province Higher Educational Science and Technology Program (2019KJJ007)。
Using the perturbative QCD approach,we studied the effects of the hadronic structure of photons on the pure annihilation rediative decays B→φγ and B_(s)→(ρ^(0),ω)γ.These decays have small branching fractions du...

Pure annihilation decay of strange beauty meson into two charm heavy mesons
《Chinese Physics C》2022年第2期62-69,共8页Behnam Mohammadi 
In this study,the heavy to heavy decay of D^(0)_(s)→D^(*+)D^(-)is evaluated through the factorization approach by using the final state interaction as an effective correction.Under the factorization approach,this dec...

Pure annihilation type B → K_0^(*±)(1430)K^((*)■) decays in the family non-universal Z’ model
《Chinese Physics C》2016年第1期28-36,共9页李营 王丹丹 吕才典 
Supported by National Natural Science Foundation of China(11175151,11575151,11375208,11235005);the Program for New Century Excellent Talents in University(NCET)by Ministry of Education of P.R.China(NCET-13-0991)
By assuming that the scalar meson K＊0 （1430） belongs to the first excited states or the lowest lying ground states of qq＇, we study the pure annihilation-type decays B→K＊0±（1430）K（＊）（-/＋） in the QCD fac...

Pure annihilation type D→PP(V) decays in the perturbative QCD approach被引量：1
《Chinese Physics C》2013年第9期1-5,共5页邹芝田 李承 吕才典 
Supported by National Science Foundation of China(11228512,11235005,11075168)
The annihilation type diagrams are difficult to calculate in any kind of model or method. Encouraged by the successful calculation of pure annihilation type B decays in the perturbative QCD factorization approach, we ...

Pure annihilation type decays B0→Ds- K2＊＋ and Bs→Da2 in perturbative QCD approach
《Chinese Physics C》2013年第1期32-35,共4页ZOU Zhi-Tian ZHOU Rui LU Cai-Dian 
Supported by National Natural Science Foundation of China （11075168）
We calculate the branching ratios of pure annihilation type decays B0→Ds- K2＊＋ and Bs→Da2 using the perturbative QCD approach based on kT factorization. The branching ratios are predicted to be （60.6-16.5-10.4-2....

Study of pure annihilation decays B_(d,s)→D^0~0
《Chinese Physics C》2008年第10期781-787,共7页李营 华娟 
National Natural Science Foundation of China (10747156, 10625525)
Within the heavy quark limit and the hierarchy approximation λQCD 〈〈 mD〈〈 mB, we analyze the B → D^0D^-0 and Bs → D^0D^-0 decays, which occur purely via annihilation type diagrams. As a rough estimate, we calcu...
