Particle Physics, Ch Hadrons: baryons, mesons and their quark content
Problem
A ground-state baryon built only from u, d and s quarks is measured to have charge Q=−1 and strangeness S=−1.
((a)) Deduce its quark content.
((b)) State whether its ground-state spin is 1/2 or 3/2, given that it belongs to the same spin family as the proton and neutron.
