Magnetic moment of the Δ++ baryon in QCD string approach
The magnetic moment of the Δ++ baryon is computed within a new approach based on the QCD string Hamiltonian. The string tension σ is the only dimensionful quantity forming the magnetic moment of both the nucleon and the Δ++ baryon; however, color Coulomb and spin-spin interactions cancel each other in the nucleon magnetic moment, while, in Δ++, they add up coherently. The result πΔ++ is in good agreement with experimental data.
