K. T. Hecht, R Le Blanc, DAVID J. ROWE · Journal of Physics A Mathematical and General · 1987
The explicit construction of an orthonormal basis for states of good spin, isospin and SU(4) Wigner supermultiplet symmetry is given in a Bargmann representation space. A complete set of quantum labels is provided by a Sp(3, R) contains/implies U(3) complementary symmetry.
