String energy in the monopole Nambu-Jona-Lasinio model

Sažetak

The string energy is calculated to the one-monopole loop approximation in the dual monopole Nambu-Jona-Lasinio (MNJL) model with dual Dirac strings by taking into account quantum fluctuations of the dual vector field and string shape fluctuations around the Abrikosov flux line. The quantum fluctuations are shown to increase the value of the string tension. The string shape fluctuations give contributions in the form of a Coulomb-like universal potential. Due to the London limit regime the scalar field exchange is taken into account in the tree approximation.
