Phenomenology of gluonium
Description
Topics on gluonium are presented. The 1/N expansion in QCD was proposed by t'Hooft. Application of the 1/N expansion to baryon is not yet satisfactory. The effective Lagrangean approach is discussed in connection with the U(1) abnormal term in QCD. A simple gluonium model can be considered, in which a gluon with finite mass constructs a bound state. A QCD sum rule on gluonium is derived. The glue-matter duality is introduced. It was found that the coupling of a gluonium (flavor singlet) and a hadron is important to understand the break of OZI law and the U(1) term. It is also necessary to give a correct method of 1/N expansion for baryon. (Kato, T.)
