摘要:In this letter, we reconsider the delicate issue of symmetry and supersymmetry breakings for
gauge theories with gauge-field mixings. The purpose is to study generalyzed potentials in the
presence of more than a single gauge potential. In this work, following a stream of investigation on
supersymmetric gauge theories without flat directions, we contemplate the possibility of building
up D- and F-term potentials by means of a gauge-field mixing in connection with a U(1)×U(1)0
-symmetry. We investigate a generalized potential including an N=1 supersymmetric extension
of the Maxwell-Chern-Simons model focusing on the study of cosmic string configurations. This
analysis sheds some light on the formation of cosmic strings for model with violation of Lorentz
symmetry.
