“…We will enumerate each of them in the following subsections. These are similar to the consistency conditions found in [15] for the closed string. The difference being that we have eliminated all the auxiliary and massive fields using equations of motion and we are dealing with open string field theory.…”

Abstract:The naive low energy effective action of the tachyon and the U(1) gauge field obtained from string field theory does not correspond to the world volume action of unstable branes in bosonic string theory. We show that there exists a field redefinition which relates the gauge field and the tachyon of the string field theory action to the fields in the world volume action of unstable branes. We identify a string gauge symmetry which corresponds to the U(1) gauge transformation. This is done to the first non linear order in the fields. We examine the vector fluctuations at the tachyon condensate till level (4,8).

Transverse Fierz–Pauli symmetry

We consider some flat space theories for spin 2 gravitons, with less invariance than full diffeomorphisms. For the massless case, classical stability and absence of ghosts require invariance under transverse diffeomorphisms (TDiff), h µν → h µν + 2∂ (ν ξ µ) , with ∂ µ ξ µ = 0. Generic TDiff invariant theories contain a propagating scalar, which disappears if the symmetry is enhanced in one of two ways. One possibility is to consider full diffeomorphisms (Diff). The other (which we denote WTDiff) adds a Weyl symmetry, by which the Lagrangian becomes independent of the trace. The first possibility corresponds to General Relativity, whereas the second corresponds to "unimodular" gravity (in a certain gauge). Phenomenologically, both options are equally acceptable. For massive gravitons, the situation is more restrictive. Up to field redefinitions, classical stability and absence of ghosts lead directly to the standard Fierz-Pauli Lagrangian. In this sense, the WTDiff theory is more rigid against deformations than linearized GR, since a mass term cannot be added without provoking the appearance of ghosts.

“…This action has a gauge invariance which agrees with the usual Yang-Mills gauge invariance to leading order, but which has higher-order corrections arising from the string field star product. A field redefinition analogous to the Seiberg-Witten map [12,13] is necessary to get a field which transforms in the usual fashion [14,15]. We identify the leading terms in this transformation and show that after performing the field redefinition our action indeed takes the Born-Infeld form in the abelian theory.…”

“…We identify the leading terms in this transformation and show that after performing the field redefinition our action indeed takes the Born-Infeld form in the abelian theory. In the nonabelian theory, there is an additional subtlety, which was previously encountered in related contexts in [14,15]. Extra terms appear in the form of the gauge transformation which cannot be removed by a field redefinition.…”

The leading terms in the tree-level effective action for the massless fields of the bosonic open string are calculated by integrating out all massive fields in Witten's cubic string field theory. In both the abelian and nonabelian theories, field redefinitions make it possible to express the effective action in terms of the conventional field strength. The resulting actions reproduce the leading terms in the abelian and nonabelian Born-Infeld theories, and include (covariant) derivative corrections.
