摘要
Magnetic moments of baryons composed of light and strange quarks are computed for the first time through the only parameter of the model-the string tension sigma. For example, mu (p) = m(p)/c root sigma, mu (Omega-) = -mu (p)[1 + 3/4(m(s)(2)/c(2)sigma) - 15/32 (m(s)(4)/c(4)sigma (2))](-1), where m(p) is the proton mass, m(s) is the strange quark current mass, and c = 0.957, a constant which is caluculated in the paper. Resulting theoretical values differ from the experimental ones typically by about 10%.
