Algebraic approach to bare nucleon matrix elements of quark operatorsZschocke, S.; Kämpfer, B.; Plunien, G.
An algebraic method for evaluating bare nucleon matrix elements of quark operators is proposed. Thereby, bare nucleon matrix elements are traced back to vacuum matrix elements. The method is similar to the soft pion theorem. Matrix elements of two-quark, four-quark and six-quark operators inside the bare nucleon are considered.
