THE WAVE FUNCTION OF VECTOR MESON BOUND STATE THROUGH SCALAR COUPLING

The wave function of the vector bound state of a spinor straton-antistraton pair through scalar coupling is discussed.The Bethe-Salpeter equation of the bound state is solved numerically,and the structural wave functions of the vector bound state are given corresponding to different selection of the parametcrs of the kernel. The magnitude of various invariant functions of the wave function is determined. The validity of the Bargman-Wigner approximation is also examined.     

ON THE SU(4) MONOPOLE AND DYON SOLUTIONS

A simple method is proposed to obtain the classical monopole and dyon solutions in the case of SU(4) symmetry, which can be systematically generalized to the general case of SU(N). The solutions obtained in the SU(4) case correspond to magnetic charges of ±1/g,±√3/(2g),±1/(√2g).     

WAVE FUNCTION OF THE PSEUDOSCALAR MESON UNDER THE INTERACTION OF A NEARLY-FLAT-BOTTOM POTENTIAL BETWEEN STRATONS

Assuming that the interactions between stratons are caused by exchanging various particles, we propose a nearly-flat-bottom potential between the stratons, which is responsible to the formation of the hadrons. Using this potential the wave function of the pseudoscalar meson is calculated and compared with those obtained by using other potentials. The results show that the nearly-flat-bottom potential possesses some obviously reasonable features, in particular, it can lead to the formation of pions with physical radius.
