Exotica possibility of new observations by BES
Ailin Zhang
The employment of interpolating currents of existed studies of four-quark state and glueball with QCD sum rule approach is analyzed. In terms of suitable currents, the masses of th…
Light Four-quark States and New Observations by BES
Ailin Zhang, Tao Huang, Tom Steele
Four-quark states are discussed within the constituent quark model. Incompleteness of existed studies of four-quark state with QCD sum rule is analyzed. The masses of diquark clust…
Diquark and light four-quark states
Ailin Zhang, Tao Huang, T. G. Steele
Four-quark states with different internal clusters are discussed within the constituent quark model. It is pointed out that the diquark concept is not meaningful in the constructio…
New interpretation to zitterbewegung
Zhi-yong Wang, Ailin Zhang
In previous investigations on zitterbewegung(zbw) of electron, it is believed that the zbw results from some internal motion of electron. However, all the analyses are made at rela…
Mass of the Lowest Scalar (0++) Glueball in the QCD Sum Rules
Tao Huang, Ai-lin Zhang
The mass of the lowest scalar glueball is discussed by using QCD sum rules. We find that the glueball mass is sensitive to the choice of moments and slightly depends on the radiati…
