Abstract

A version of the chiral bag model, which contains the linear s-model dynamics and is quantized by using the constituent quark operators, has been solved using a Tamm-Dancoff inspired approximation. Model gives reasonable values for the axial coupling constant g_A = Delta u - Delta d = 1.28, for the combination h_A^S = Delta u + Delta d = 0.38, and for the proton magnetic moment mu_p = 2.77. These values, which match the combinations Delta u ± Delta d of the quark density functions, are consequences of the chiral character of the model.
