AbstractAbstract
[en] An effective Lagrangian describing interactions between a scalar glueball and pseudoscalar Goldstone mesons is suggested. This model reproduces correctly the trace anomaly of the energy-momentum tensor of QCD and some low-energy theorems. It illustrates explicitly the SU(2) x SU(2) coupling mechanism of a scalar glueball to pseudoscalar mesons. the model is in a reasonable agreement with glueball assignment for g sub(s) (1240) state
