Instanton contribution to scalar charmonium and glueball decays
Valeriu Zetocha, Thomas Schaefer
We study instanton contributions to hadronic decays of the scalar glueball, the pseudoscalar charmonium state , and the scalar charmonium state . Hadronic decays of the $…

QCD and the eta prime Mass: Instantons or Confinement?
Thomas Schaefer
We argue that lattice calculations of the mass in QCD with colors performed at non-zero baryon chemical potential can be used to study the mechanism responsible for th…
