1-27 Unquenched Quark-model Calculation of Excited p Resonances and P-wave  Phase Shifts
《IMP & HIRFL Annual Report》2015年第1期38-38,共1页Susana Coito G. Rupp E. van Beveren 
In Ref. [1], (770) vector resonance, its radial recurrences, and the corresponding P-wave  phase shifts were investigated in an unquenched quark model with all classes of relevant decay channels included, viz. pseu...

Radial Excitations in the Global Colour Soliton Model
《Chinese Physics Letters》2007年第8期2208-2211,共4页王斌 刘玉鑫 
Supported by the National Natural Science Foundation of China under contract Nos 10425521, 10575004 and 106750077 the Key Project of the Ministry of Education of China under Grant No 305001, the Research Fund for the Doctoral Programme of Higher Education of China under Grant No 20040001010, and the Foundation for University Key Teachers by the Ministry of Education of China.
With the Munczek-Nemirovsky model of the effective gluon propagator in the global colour model, we study the radially excited solitons in which one quark is excited and the other two are at the ground state. The obtai...

Analysis of X(1576) as a Tetraquark State with the QCD Sum Rules
《Chinese Physics Letters》2006年第12期3208-3210,共3页王志刚 完绍龙 
Supported by the National Natural Science Foundation under Grant No 10405009, and the Key Program Foundation of North China Electric Power University.
We take the viewpoint that X(1576) is the tetraquark state which consists of a scalar diquark and an antiscalar-diquark in relative P-wave, and calculate its mass in the framework of the QCD sum rule approach. The n...
