Treatment of broken symmetry in the Faddeev approach to the strange baryon spectra
arXiv:1202.4488 · doi:10.1103/PhysRevD.85.114042
Abstract
By solving the Faddeev equations we calculate the mass of the strange baryons in the framework of a relativistic constituent quark model. The Goldstone-boson-exchange quark-quark interaction is derived from symmetry, which is explicitly broken as the strange quark is much heavier. This broken symmetry can nicely be accounted for in the Faddeev framework.
