An excursion into the string spectrum

Abstract We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive li

Extracting bigravity from string theory

Abstract The origin of the graviton from string theory is well understood: it corresponds to a massless state in closed string spectra, whose low-energy effective action, as extracted from string scattering amplitudes, is that of Einstein-Hilbert. In

Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry

Autor: Ignatios Antoniadis, Jean-Pierre Derendinger, Chrysoula Markou

Publikováno v: Journal of High Energy Physics, Vol 2017, Iss 6, Pp 1-38 (2017)

Abstract We study the partial breaking of N = 2 $$ \mathcal{N}=2 $$ global supersymmetry, using a novel formalism that allows for the off-shell nonlinear realization of the broken supersymmetry, extending previous results scattered in the literature.

We consider the most general Kaluza-Klein (KK) compactification on $S^1/\mathbb{Z}_2$ of a five dimensional ($5D$) graviton-dilaton system, with a non-vanishing dilaton background varying linearly along the fifth dimension. We show that this backgrou

In this work we present the minimal supersymmetric extension of the five-dimensional dilaton-gravity theory that captures the main properties of the holographic dual of little string theory. It is described by a particular gauging of $$\mathcal {N}=2
