Understanding the branching ratios of χ_{c1}\toϕϕ, ωω, ωϕobserved at BES-III
Dian-Yong Chen, Jun He, Xue-Qian Li +1
In this work, we discuss the contribution of the mesonic loops to the decay rates of which are suppressed by the helicity selection rules and whi…
The Simplest Dark-Matter Model, CDMS II Results, and Higgs Detection at LHC
Xiao-Gang He, Tong Li, Xue-Qian Li +2
The direct-search experiment for dark matter performed by the CDMS II Collaboration has observed two candidate events. Although these events cannot be interpreted as significant ev…
Determining the mixing by the newly measured
Hong-Wei Ke, Xue-Qian Li, Zheng-Tao Wei
The mixing of or is of a great theoretical interest, because it concerns many aspects of the underlying dynamics and hadronic structure of pseudoscalar mesons and g…
Radiative and flavor-violating transitions of leptons from interactions with color-octet particles
Yi Liao, Ji-Yuan Liu
It has been recently proposed that neutrino mass could originate from Yukawa interactions of leptons with new colored particles. This raises the interesting possibility of testing…
Fermion correction to the mass of the scalar glueball in QCD sum rule
Xu-Hao Yuan, Liang Tang
Contributions of fermions to the mass of the scalar glueball are calculated at two-loop level in the framework of QCD sum rules. It obviously changes the coefficients in t…
Study of the branching ratio of in scattering
Hai-Bo Li, Xiao-Shuai Qin, Mao-Zhi Yang
Based on the data of BES and Belle, the production of in the scattering process is studied in this paper. We analyze the continuum and resonant cont…
