A possible coupling of a scalar glueball to pseudoscalar Goldstone mesons
Description
An effective lagrangian describing interactions between a scalar glueball and pseudoscalar Goldstone mesons is suggested. This lagrangian model reproduces correctly the trace anomaly of the energy-momentum tensor of QCD and some low-energy theorems. It illustrates explicitly the SU(2)xSU(2) coupling mechanism of a scalar glueball to pseudoscalar mesons. The model is in a reasonable agreement with glueball assignment for the gsub(s) (1240) state.
