Study of the η'→Ve^+e^- decay with hidden local symmetry model
《Chinese Physics C》2015年第2期15-19,共5页杨悦玲 黄金书 鲁公儒 
Supported by National Natural Science Foundation of China(11147008,11275057,U1332103,U1232101);Program for Science and Technology Innovation Talents in Universities of Henan Province(2012HASTIT030)
Within the hidden local symmetry framework, the Dalitz decay η→Ve+e-is studied with the vector meson dominance model. It is found that the partial width Γ(η→ωe+e-)≈40 e V and branching ratio B(η→ωe+e-...

Study of the B_c→B_sπ decay with the perturbative QCD approach
《Science China(Physics,Mechanics & Astronomy)》2014年第10期1891-1897,共7页SUN JunFeng YANG YueLing LU GongRu 
supported by the National Natural Science Foundation of China(Grant Nos.11147008,U1232101 and 11275057)
The Bc → Bsπ decay is studied with the perturbative QCD approach. Three types of wave functions for Bs meson are considered. The transition form factor F0Bc → Bsπ (0) and the branching ratio IBr(Bc → Bsπ) ar...

On the measurement for the speed of gravity
《Chinese Science Bulletin》2014年第9期828-832,共5页Linxia Liu Chenggang Shao 
supported by the National Natural Science Foundation of China(11275057)
Newton’s law of gravity is a theory of instantaneous action at a distance.However,Einstein’s general relativity states that the speed of gravity equals the speed of light,which is finite.Therefore,it is a worthy pro...

广义相对论中引力传播速度的测量问题被引量:1
《科学通报》2014年第4期323-327,共5页刘琳霞 邵成刚 
国家自然科学基金(11275057)资助
牛顿万有引力定律认为引力场的传播不需要时间,是瞬时相互作用,而广义相对论认为瞬时相互作用是不存在的.因此,在观测和研究引力潮汐时,牛顿万有引力定律是否需要修改是一个值得探讨的问题.本文说明在现有的广义相对论框架下,牛顿引力...

Re-estimatation of the Upper Limit on the Photon Mass with the Solar Wind Method
《Chinese Physics Letters》2012年第11期36-39,共4页LIU Lin-Xia SHAO Cheng-Gang 
Partially supported by the National Natural Science Foundation of China(11275057).
The currently accepted value for the upper limit on the photon rest mass comes from a rough estimate based on the solar wind method.We reconsider this method and present a more detailed analysis of the electromagnetic...
