34 | // Short description: This is the basic class of the CHIPS model. It |
---|
35 | // describes the quark content of the Quasmon, which is a generalized |
---|
36 | // hadronic state. All Quasmons are bags, characterized by the quark |
---|
37 | // Content (QContent), but the spin is not fixed and only light (u,d,s) |
---|
38 | // quarks are considered (SU(3)). The hadrons are the ground states for |
---|
39 | // the corresponding quasmons. The Chipolino (G4QChipolino) or nuclear |
---|
40 | // cluster are examples for another Quark Content. |
