Wigner 6j symbols for SU(N): Symbols with at least two quark-lines
Judith Alcock-Zeilinger, Stefan Keppeler, Simon Plätzer +1
We study a class of SU(N) Wigner 6j symbols involving two fundamental representations, and derive explicit formulae for all 6j symbols in this class. Our formulae express the 6j sy…
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…
A simple counting argument of the irreducible representations of SU(N) on mixed product spaces
Judith Alcock-Zeilinger, Heribert Weigert
It is a well known result that the number of irreducible representations of SU(N) on a tensor product containing k factors of a vector space V is given by the number of involutions…
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…
