Ramond equations of motion in superstring field theory [PDF]

open access: yes, 2015
A bstractWe extend the recently constructed NS superstring field theories in the small Hilbert space to give classical field equations for all superstring theories, including Ramond sectors.

Superstring limit of Yang–Mills theories [PDF]

open access: yesPhysics Letters B, 2016
It was pointed out by Shifman and Yung that the critical superstring on $X^{10}={\mathbb R}^4\times Y^6$, where $Y^6$ is the resolved conifold, appears as an effective theory for a U(2) Yang-Mills-Higgs system with four fundamental Higgs scalars defined on $ _2\times{\mathbb R}^2$, where $ _2$ is a two-dimensional Lorentzian manifold.

Unification of Gravity and Internal Interactions

open access: yesFortschritte der Physik, Volume 72, Issue 1, January 2024.
Abstract In the gauge theoretic approach of gravity, general relativity is described by gauging the symmetry of the tangent manifold in four dimensions. Usually the dimension of the tangent space is considered to be equal to the dimension of the curved manifold. However, the tangent group of a manifold of dimension d is not necessarily SOd$SO_d$.

Erratum to: Cutkosky rules for superstring field theory

open access: yesJournal of High Energy Physics, 2018
Superstring field theory expresses the perturbative S-matrix of superstring theory as a sum of Feynman diagrams each of which is manifestly free from ultraviolet divergences.

Yang-Baxter deformations of the AdS 5 × T 1,1 superstring and their backgrounds

open access: yesJournal of High Energy Physics, 2021
We consider three-parameter Yang-Baxter deformations of the AdS 5 × T 1,1 superstring for abelian r-matrices which are solutions of the classical Yang-Baxter equation.

A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations

open access: yesAdvances in Astronomy, Volume 2024, Issue 1, 2024.
In this work, we study the cosmological dynamics of the early universe by employing a small field potential in the context of multifield inflation. By investigating analytically the cosmological observables, such as the number of e‐folds N, potential slow‐roll parameters ϵV, ηV, and spectral index ns which carry significant information, we show that ...

Quantisation of type IIB superstring theory and the matrix model

open access: yesJournal of High Energy Physics
We discuss the path-integral quantisation of perturbative string theory and show equivalence between the Polyakov-type, Schild-type and Nambu-Goto-type formulations of critical type II superstring theory.

Gauge bosons in superstring theory

open access: yesNuclear Physics B, 1994
Abstract Gauge bosons in the Ramond-Ramond sector of four-dimensional models based on the superstring are analyzed. The normalization of degenerate bispinor vacuum states is compared with that of Neveu-Schwarz gauge bosons, an explicit k0 dependence is shown to be isolated when the polarization vectors are chosen to be in ϵ0 = 0 gauge; a spin ...

Twistor Superstring in 2T-Physics

open access: yes, 2004
By utilizing the gauge symmetries of Two-Time Physics (2T-physics), a superstring with linearly realized global SU(2,2|4) supersymmetry in 4+2 dimensions (plus internal degrees of freedom) is constructed.
