eta(1405) in a chiral approach based on mixing of the pseudoscalar glueball with the first radial excitations of eta and eta'
Thomas Gutsche, Valery E. Lyubovitskij, Malte C. Tichy
The supernumerous eta(1405) is considered a strong candidate for the pseudoscalar glueball. In a phenomenological chiral approach, we consider a mixing scenario of bare pseudoscala…
Strong decays of radially excited mesons in a chiral approach
Thomas Gutsche, Valery E. Lyubovitskij, Malte C. Tichy
We study radial excitations of pseudoscalar and vector (q bar q) mesons within a chiral approach. We derive a general form for a chiral Lagrangian describing processes involving ex…
Light Hadron Spectrum in the Instanton Liquid Model
P. Faccioli, M. Cristoforetti, M. C. Tichy +1
We review our recent study of the role played by the chiral interactions induced by instantons, in the lowest-lying sector of the light hadron spectrum. We discuss how the ordering…
The Scalar Glueball in the Instanton Vacuum
M. C. Tichy, P. Faccioli
We study the contribution of instantons to the binding and the mass of the lightest scalar glueball, in gluondynamics. We show that the short-range correlations introduced by such…
