Pseudoscalar Field as a Possible Candidate for Phantom Field

open access: yesAdvances 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

Mixed boundary states from 1-loop bosonic closed strings

open access: yes, 2013
We analyze in a simple calculation the way 2-dimensional moduli induce a noise-like mixing between the right and left sectors of the 1-loop partition function of bosonic closed strings.

T‐Symmetry in String Geometry Theory

open access: yesAdvances 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 ...

Bosonic strings

open access: yes, 2007
This book presents a mathematical treatment of Bosonic string theory from the point of view of global geometry. As motivation, Jost presents the theory of point particles and Feynman path integrals. He provides detailed background material, including the

Boundary action and profile of effective bosonic strings

open access: yes, 2023
The mean-square width of the energy profile of bosonic string is calculated considering two boundary terms in the effective action. The perturbative expansion of the Lorentz-invariant boundary terms at the second and the fourth order in the effective ...

QUANTUM GEOMETRY OF BOSONIC STRINGS

open access: yesPhysics Letters B, 1981
We develop a formalism for computing sums over random surfaces which arise in all problems containing gauge invariance (like QCD, three-dimensional Ising model etc.). These sums are reduced to the exactly solvable quantum theory of the two-dimensional Liouville lagrangian.

Modified 3D Massive Abelian 2‐Form Theory With a Single Pseudoscalar Field as a Phantom Field: BRST Approach

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
We obtain the off‐shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti‐BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three (2 + 1)‐dimensional (3D) Abelian two‐form gauge theory with a single pseudoscalar field. The latter field (having the negative kinetic term

Open String Renormalization Group Flow as a Field Theory

open access: yesFortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract This article shows that the integral flow‐lines of the RG‐flow of open string theory can be interpreted as the solitons of a Hořova–Lifshitz sigma‐model of open membranes. The authors argue that the effective background description of this model implies the g‐theorem of open string theory.

Bosonic string algebras

open access: yesPhysics Letters B, 1985
We discuss some aspects of symmetry breakings in string theories. We mainly focus on the algebra of bosonic strings, but suspect similar ideas may be used for superstring theories. We point out a curious relation between the partition function of certain bosonic string theories and superstring theories.

Effective action of bosonic string theory at order α ′3

open access: yesJournal of High Energy Physics
In this work, we derive the classical effective action of bosonic string theory at order α ′3 for the metric, Kalb-Ramond field, and dilaton by imposing a higher-derivative extension of the Buscher rules on the circular reduction of the minimal basis at ...
