Static baryon properties and SU(3) symmetry breaking effects in a relativistic quark model with linear potential
European Physical Journal C(1985)
Abstract
Starting from a Dirac equation with a scalar linear confinement potential for quarks we calculate static properties ofS-wave baryons, such as magnetic moments, axial vector coupling constants and the proton charge radius. In addition we pursue the renormalization of weak decay constants originating from the influence of quark masses on the baryonic wave functions. The static baryon properties compare well with data andSU(3) symmetry breaking effects are found to be small in agreement with recent results on semileptonic hyperon decays.
