A Gauge Invariant Electromagnetic Two-Point Function For Heavy Light Quark Systems

Abstract

A gauge invariant electromagnetic two-point function, crucial to the investigations of the violation of isospin symmetry, is derived for heavy-light quark systems. Thus QED can be consistently introduced into the QCD Sum Rule method, which was not previously possible.
