Problem
The Δ− baryon has quark content ddd. Each d quark carries baryon number B=1/3, third component of isospin I3=−1/2 and strangeness S=0. Hypercharge is Y=B+S.
((a)) Find the total baryon number, I3 and Y of Δ−.
((b)) Plot the point (I3,Y) and say which row of the spin-three-halves pattern it belongs to (the four-member row, the three-member row, or the two-member row).
