Applications of instantons to hadronic processes
Valeriu Zetocha
In this thesis we study two processes in which instantons may play an important role: the decays of charmonium states , and glueball and the OZI violation in channels re…

Instantons and the Spin of the Nucleon
T. Schaefer, V. Zetocha
Motivated by measurements of the flavor singlet axial coupling constant of the nucleon in polarized deep inelastic scattering we study the contribution of instantons to OZI violati…

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 $…
