Three-quark exchange operators, crossing matrices and Fierz transformations in SU(2) and SU(3)

Abstract

We give explicit expressions for the three-quark exchange operators, crossing matrices and Fierz transforms for the SU(2) and SU(3) groups. We identify the invariant terms in these operators and express them in terms of Casimir operators.
