Four - Quark Model for Charm States
A recently proposed four-quark mechanism is shown to generate the charm spectroscopy and explain many features of the data. The model implies an n, degenerate with x(3415) and a number of new effects.

متن کاملChiral Quark Model
Abstract. In this talk I review studies of hadron properties in bosonized chiral quark models for the quark flavor dynamics. Mesons are constructed from Bethe–Salpeter equations and baryons emerge as chiral solitons. Such models require regularization and I show that the two–fold Pauli–Villars regularization scheme not only fully regularizes the effective action but also leads the scaling laws ...

متن کاملTwo Nucleon-States in a Chiral Quark-Diquark Model
We study the ground and first excited states of nucleons in a chiral quark-diquark model. We include two quark-diquark channels of the scalar-isoscalar and axial-vector-isovector types for the nucleon states. The diquark correlation violating the spin-flavor SU(4)SF symmetry allows to treat the two quark-diquark channels independently. Hence the two states appear as the superpositions of the tw...
