New Covariant Gauges in String Field Theory
Abstract
A singleparameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. This is a natural string field counterpart to the covariant gauge in the conventional gauge theory, which includes the Landau gauge, as well as the Feynman (Siegel) gauge as special cases. The action in the Landau gauge is greatly simplified in such a manner that many of the component fields have no derivatives in their kinetic terms and appear in at most quadratic forms in the vertex.
