Adding stubs to quantum string field theories

open access: yesJournal of High Energy Physics
Generalizing recent work by Schnabl-Stettinger and Erbin-Fırat, we outline a universal algebraic procedure for ‘adding stubs’ to string field theories obeying the BV quantum master equation.

On String Field Theory and Effective Actions

open access: yes, 1992
A truncation of string field theory is compared with the duality invariant effective action of $D=4, N=4$ heterotic strings to cubic order. The three string vertex must satisfy a set of compatibility conditions.

String Field Theory

open access: yes
After more than 50 years from the Veneziano amplitude, the fundamental formulation of string theory (ST) remains elusive. On the one hand, there is the world-sheet formulation that is truly microscopic but which is only valid for infinitesimal string coupling and is highly background dependent.

The T-dual symmetries of a bosonic string

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We investigate whether the symmetry transformations of a bosonic string are connected by T-duality. We start with a standard closed string theory. We continue with a modified open string theory, modified to preserve the symmetry transformations possessed

String field theory

open access: yesNuclear Physics B, 1986
A gauge invariant field theory of the bosonic string is formulated following Siegel, Banks and Peskin, and Feigin and Fuks. The free field action is constructed from the Virasoro operators assuming only locality. The propagator is very regular at short distance.

Open String Field Theory around Universal Solutions

open access: yes, 2002
We study the physical spectrum of cubic open string field theory around universal solutions, which are constructed using the matter Virasoro operators and the ghost and anti-ghost fields. We find the cohomology of the new BRS charge around the solutions,

The bosonic string on string-size tori from double field theory

open access: yesJournal of High Energy Physics, 2017
We construct the effective action for toroidal compactifications of bosonic string theory from generalized Scherk-Schwarz reductions of double field theory.

Novel string field theory with also negative energy constituents/objects gives Veneziano amplitude

open access: yesJournal of High Energy Physics, 2018
We have proposed a new type of string field theory. The main point of the present article is to cure some technical troubles: missing two out three terms in Veneziano amplitude. Our novel string field theory, describes a theory with many strings in terms

Duality of string amplitudes in a curved background

open access: yes, 1992
We initiate a program to study the relationship between the target space, the spectrum and the scattering amplitudes in string theory. We consider scattering amplitudes following from string theory and quantum field theory on a curved target space, which
