## Abstract

The superstring theory in the light-cone gauge admits various gauge symmetries. Therefore, we gauge the superstring sigma model in the light-cone gauge under the gauge group SU(4). Some properties of the gauged action and the corresponding current will be studied. Besides, two modified actions for the superstring will be obtained.
