Top Quark Forward-Backward Asymmetry in the Little Higgs Model
Xing-Dao Guo, Yin-Jie Zhang, Shu-Min Zhao +3
We calculate the forward backward asymmetry of the top-pair production at TEVATRON up to next to leading order (NLO) in the little Higgs model (LHM). We find that the contribution…
The FSI contribution to the observed decays into and
Xu-Hao Yuan, Hong-Wei Ke, Xiang Liu +1
Because at the tree level is Cabibbo-triple suppressed, so its branching ratio should be smaller than that of . The measurements present a r…
Is a Molecular State?
Hong-Wei Ke, Xue-Qian Li, Yan-Liang Shi +2
Whether molecular states indeed exist in nature has been disputed for a long time. Several new resonances have been observed in the recent experiments and they seem to be of exotic…
Study on the mixing among the mesons around with the QCD sum rules
Xu-Hao Yuan, Liang Tang, Mao-Zhi Yang +1
We calculate the correlation functions of , and glueball in the QCD sum rules and obtain the mass matrix where non-diagonal terms are determined by the…
Study of Doubly Heavy Baryon Spectrum via QCD Sum Rules
Liang Tang, Xu-Hao Yuan, Cong-Feng Qiao +1
In this work, we calculate the mass spectrum of doubly heavy baryons with the diquark model in terms of the QCD sum rules. The interpolating currents are composed of a heavy diquar…
Fraction of the gluonium component in and
Hong-Wei Ke, Xu-Hao Yuan, Xue-Qian Li
It is interesting to determine the fraction of the gluonium component in and which has been under serious discussion for many years. Measurements on different decay and/or…
Re-study on the contribution of scalar potential and spectra of , and families
Xu-Hao Yuan, Hong-Wei Ke, Yi-Bing Ding +1
We indicated in our previous work that for QED the role of the scalar potential which appears at the loop level is much smaller than that of the vector potential and in fact neglig…
Phenomenological study on the significance of the scalar potential and Lamb shift
Xu-Hao Yuan, Hong-Wei Ke, Xue-Qian Li
We indicated in our previous work that for QED the contributions of the scalar potential which appears at the loop level is much smaller than that of the vector potential and in fa…
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…
