| 英文摘要 | The Eigenstate Method has been developed to deduce the fermion propagator with a constant external magnetic field. In general, we find its result is equivalent to other methods and this new method is more convenient, especially when one evaluates the contribution from the infinitesimal imaginary term of the fermion propagator. Using the Eigenstate Method we try to discuss whether the infinitesimal imaginary frequency of the fermion propagator in a strong magnetic field and Lorentz-violating extension of the minimal SU(3) x SU(2) x SU(1) Standard Model could have a significant influence on the dynamical mass. When the imaginary term of the fermion propagator in this model is not trivial (root(alpha - 1)eB/3 < sigma < root(alpha - 1)2eB/3), this model gives a correction to the dynamical mass. When one does not consider the influence from the imaginary term (sigma > root(alpha - 1)2eB/3), there is another correction from the conventional term. Under both circumstances, chiral symmetry is broken. |
