Within the Nambu-Jona-Lasinio model strange degrees of freedom are incorporated into the soliton picture using the collective approach of Yabu and Ando. The form factors of the nucleon associated with the nonet vector current are extracted. The numerical results provide limits for the strange magnetic moment: -0.05 ≤ μ s ≤ 0.25. For the strange magnetic form factor of the nucleon the valence...
We give the analytic expression of the next-to-leading order contribution to the longitudinal gluons energy in high-temperature quantum chromodynamic using the real-time formalism of finite-temperature quantum field theory. We also give the expressions of the effective propagators and vertex functions.
