Component Of The Gluon Model Glueball State

Glueballs reflect new degrees of freedom brought into hadron spectroscopy by QCD and are therefore of prime interest. But for some reasons there is none of the glueball candidates which have been identified to a real glueball. So the theoretical prediction of the property on glueballs is necessary, the mass of glueballs is the most important property in search for glueballs. By means of the constiuent gluon model in which gluon has dynamical mass and one spin, the potential of two-gluon glueball systems can be obtained. From the Hamiltonian of two-gluon glueball systems, we can calculate the spectrum of two-gluon glueballs. Wei-Shu Hou et.al used the potential model by Cornwall and Soni, gained the gluon-gluon potential. Taking advantage of the potential and perturbative mothed , the spectrum of two-gluon glueballs are calculated with principle quantum number below n=3 . It is found that the theoretical results can correspond to the experimental data, are sometimes even better than the lattice calculations.
