Baryon magnetic moments in the QCD string approach (the Nonperturbative QCD approach)

Magnetic moments of baryons composed of light and strange quarks are computed for the first time through the only parameter of the model-- string tension $\sigma$. For example, $\mu_p= m_p/c\sqrt{\sigma},$ $\mu_{\Omega^-}=-\mu_p(1+\frac34 \frac{m^2_s}{c^2\sigma}-{15/32} \frac{m^4_s}{c^4\sigma^2})^{-1}$, where magnetic moments are expressed in nuclear magnetons, $m_p$ is the proton mass, $m_s$ is the strange quark current mass, $c=0.957$ -- a constant which is caluculated in the paper. Resulting theoretical values differ from the experimental ones typically by about 10%.
