New Covariant Gauges in String Field Theory

Abstract: A single-parameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. It is a natural string field counterpart of 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 largely simplified in such a way that numerous component fields have no derivatives in their kinetic terms and appear in at most quadratic in the vertex.Comment: 24 page

“…For each linear gauge fixing condition specified by bpz(O 3 ), we can write the gauge fixed action as [14] S GF = − 1 2 where Φ n and B n are Grassmann odd string fields. They are expanded by the ghost number n states with the corresponding Grassmann parity (−1) n−1 component fields.…”

“…With assuming suitable gauge fixing, we perform path integral for χ a andχ a and obtain a determinant factor det(Q T0 + φ + χ) −1 (11) in the partition function. In the following sections, we will evaluate this determinant by truncating the string field rather than imposing conventional gauge condition such as linear gauge [18].…”
