Recent J/ψ Results from Bes II
N. F. Zhou
Abstract
Multiquark searches have been a hot topic in recent years. Some threshold enhancements were observed during the analysis of 58M events collected by BES II detector. These enhancements can't be explained by the standard model and may be candidates of multiquark. BES also contribute a lot to the study of light scalar mesons, such as σ,κ,f0(1370) and f0(1710) etc. Study of the excited baryon states and measurements of some decays are also done with the events of BES.
