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

Journal 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.

Dilaton Contact Terms in the Bosonic and Heterotic Strings

, 1992
Dilaton contact terms in the bosonic and heterotic strings are examined following the recent work of Distler and Nelson on the bosonic and semirigid strings. In the bosonic case dilaton two-point functions on the sphere are calculated as a stepping stone

Strings in AdS_3 and the SL(2,R) WZW Model. Part 1: The Spectrum [PDF]

, 2000
In this paper we study the spectrum of bosonic string theory on AdS_3. We study classical solutions of the SL(2,R) WZW model, including solutions for long strings with non-zero winding number.

Symmetries in the Hamiltonian Formulation of String Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
In the context of the Hamiltonian formulation of string theory, a widely acknowledged issue is the inability of the first‐class constraints to accurately reproduce the Lagrangian symmetry transformations. We take a critical look at the Hamiltonian formulation of the Polyakov string and demonstrate, using Castellani′s procedure, that diffeomorphism and ...

(m, n)-string and D1-brane in stringy Newton-Cartan background

Journal of High Energy Physics, 2019
This paper is devoted to the analysis of (m, n)-string in stringy Newton-Cartan background. We start with the Hamiltonian constraint for (m, n)-string in general background and perform limiting procedure on metric and NSNS and Ramond-Ramond two form ...

Pseudoscalar Field as a Possible Candidate for Phantom Field

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We demonstrate the existence of a single pseudoscalar (PS) field in the mathematically backed and parity‐preserving modifications of the standard Stückelberg formalism (SSF) in the context of the Lagrangian formulation of the (i) two (1 + 1)‐dimensional (2D) massive Abelian 1‐form gauge theory, (ii) three (2 + 1)‐dimensional (3D) massive Abelian 2‐form

Conformal to Harmonic Gauge for Bosonic Strings

, 2018
We consider Polyakov theory of Bosonic strings in conformal gauge which are used to study conformal anomaly. However it exhibits ghost number anomaly. We show how this anomaly can be avoided by connecting this theory to that of in background covariant ...

T‐Symmetry in String Geometry Theory

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Bosonized string ghosts

Nuclear Physics B, 1987
Abstract A precise treatment of ghost bosonization is given in the operator framework without employing conformal field theory techniques. This is then applied to reformulate Virasoro BRS cohomology using bosonic coordinates but without a ghost number degree of freedom. Subsequent analysis reveals a rather elegant structure.
