Compact construction algorithms for the singlets of SU(N) over mixed tensor product spaces
Judith Alcock-Zeilinger, Heribert Weigert
The irreducible representations of SU(N) over a mixed quark-antiquark Fock space component have been studied for many years. In analogy to the case for the quark-only Fock space co…
Compact Hermitian Young Projection Operators
Judith Alcock-Zeilinger, Heribert Weigert
In this paper, we describe a compact and practical algorithm to construct Hermitian Young projection operators for irreducible representations of the special unitary group SU(N), a…
Transition Operators
Judith Alcock-Zeilinger, Heribert Weigert
In this paper, we give a generic algorithm of the transition operators between Hermitian Young projection operators corresponding to equivalent irreducible representations of SU(N)…
Simplification Rules for Birdtrack Operators
Judith Alcock-Zeilinger, Heribert Weigert
This paper derives a set of easy-to-use tools designed to simplify calculations with birdtrack op- erators comprised of symmetrizers and antisymmetrizers. In particular, we present…
