Proton Spin in the Instanton Background

Reference: Technical Report LMU-95-15, hep-ph/9509402

Abstract: The proton form factors are reduced to vacuum correlators of 4 quark fields by assuming independent constituent quarks. The axial singlet quark and gluonic form factors are calculated in the instanton liquid model. A discussion of gauge(in)dependence is given.
