Tests for Cosmological Evolution of a Brane Universe Model
Xinhe Meng, Jingmin Hou, Kaiyi Lu +1
The relativistic Friedmann Lemaitre cosmology model (FLCM) is very sucessful to describe the evolution history of the Universe from the " First three Minutes". Any alternative mode…
SU(3) and Nonet Breaking Effects in Induced by due to Anomaly
X. -G. He, C. -S. Huang, X. -Q. Li
In this paper we study the effects of on in the Standard Model. We find that this interaction can induce new sizeable SU(3) and U(3) nonet breaking…
Neutrinoless Double Beta Decay in Supersymmetric Seesaw model
Tai-Fu Feng, Xue-Qian Li, Yan-An Luo
Inspired by the recent HEIDELBERG-MOSCOW double beta decay experiment, we discuss the neutrinoless double beta decay in the supersymmetric seesaw model. Our numerical analysis indi…
A Measurement of Psi(2S) Resonance Parameters
BES Collaboration, J. Z. Bai
Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been measured in the vicinity of the Psi(2S) resonance using the BESII detector operated at the BEPC. The Psi(2S) t…
Cabibbo-suppressed non-leptonic decays of Lambda_c and final state interaction
Shao-Long Chen, Xin-Heng Guo, Xue-Qian Li +1
With the diquark structure of Lambda_c, we investigate the branching ratios of Lambda_c -> n pi^+ and p pi^0. The results show that without considering the final state interaction…
Strange sea asymmetry in nucleons
Xue-Qian Li, Xiao-Bing Zhang, Bo-Qiang Ma
We evaluate the medium effects in nucleon which can induce an asymmetry of the strange sea. The short-distance effects determined by the weak interaction can give rise to $δm\equiv…
