# Light-Cone Gauge String Field Theory in Noncritical Dimensions - High Energy Physics - Theory

Abstract: We study light-cone gauge string field theory in noncritical space-timedimensions. Such a theory corresponds to a string theory in a Lorentznoninvariant background. We identify the worldsheet theory for the longitudinalcoordinate variables $X^\pm$ and study its properties. It is a CFT with theright value of Virasoro central charge, using which we propose a BRST invariantformulation of the worldsheet theory.
