Matrix elements of SU(6) generators for baryons at arbitrary N-c

[en] We present explicit formulas for the matrix elements of the SU(6) generators for totally symmetric spin-flavor states, relevant for baryon spectroscopy in large N-c QCD. We rely on the interplay between two different methods to calculate these matrix elements. As an outcome, general analytic formulas of the corresponding SU(6) isoscalar factors are derived for arbitrary N-c. These results can be used to study excited states of nonstrange and strange baryons.
