Abelian instantons and monopole scattering
Abstract It is usually assumed that 4D instantons can only arise in non-Abelian theories. In this paper we re-examine this conventional wisdom by explicitly constructing instantons in an Abelian gauge theory: QED 4 with N f flavors of Dirac fermions, in the background of a Dirac monopole. This is th...
