Duality of string amplitudes in a curved background
, 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

String Field Theory and Perturbative Dynamics of Noncommutative Field Theory [PDF]
, 2000 The perturbative dynamics of noncommutative field theory (NCFT) is discussed from a point view of string field theory. As in the commutative case it is inevitable to introduce a closed string, which may be described as a bound state of two noncommutative

Closed string amplitudes around tachyon vacuum solution in Kaku theory
Journal of High Energy PhysicsWe incorporate closed string field into Kaku’s open string field theory which is defined using Kaku vertex, and we construct open-closed string field theory.

Topological defects in open string field theory
Journal of High Energy Physics, 2018 We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of Graham and Watts to include the action of defects on boundary condition ...

STRING FIELD THEORY FROM QUANTUM GRAVITY [PDF]
Reviews in Mathematical Physics, 2013 Recent work on neutrino oscillations suggests that the three generations of fermions in the standard model are related by representations of the finite group A(4), the group of symmetries of the tetrahedron. Motivated by this, we explore models which extend the EPRL model for quantum gravity by coupling it to a bosonic quantum field of representations

N-String Vertices in String Field Theory [PDF]
, 1993 We give the general form of the vertex corresponding to the interaction of an arbitrary number of strings. The technique employed relies on the ``comma" representation of String Field Theory where string fields and interactions are represented as ...

Normalization of ZZ instanton amplitudes in minimal string theory
Journal of High Energy Physics, 2022 We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane.

Nuclear 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
, 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,

Closed Strings Tachyons and Non-Commutative Instabilities [PDF]
, 2003 We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non ...
