英文摘要:
The dynamical breaking of the supergauge symmetry in the massless supergauge Wess-Zumino model is discussed without adding the Fayet-Iliopoulos term to the Lagrangian. It is shown, in terms of the Nambu-Jona-Lasinio mechanism, that the supergauge symmetry breaking can be realized dynamically in the massless supergauge Wess-Zumino model. The supergauge symmetry behavior at finite temperatures is also investigated and it is shown that the supergauge symmetry broken dynamically at zero temperature can be restored at finite temperatures.
