Abstract
Magnetic moments of S11(1535) and S11(1650)
baryons are studied in the framework of the relativistic
three-quark Hamiltonian derived in the Field Correlation Method.
The baryon magnetic moments are expressed via the average current
quark energies which are defined by the fundamental QCD
parameters: the string tension σ, the quark masses, and the
strong coupling constant αs.
Resulting magnetic moments for the
JP=1/2- nucleons are compared both to model calculations and
to those from lattice QCD.
