Matrix elements of image generators for baryons with arbitrary image quarks in mixed symmetric states image Original Research Article

We derive general analytic formulae for the matrix elements of the SU(6) generators for mixed symmetric [Nc−1,1] spin-flavor states with an arbitrary number Nc of quarks. They are relevant for baryon spectroscopy in the 1/Nc expansion method applied to light baryons and can be used to study excited states. In this way previous work on non-strange baryons can be extended to both non-strange and strange baryons.
