On generalized fractional superstring theory [PDF]

Classical and Quantum Gravity, 1997
The aim of this paper is to explore new invariances of the worldsheet extending the previous ones and to look for eventual generalized fractional superstring models by using higher-dimensional parafermionic cosets. Among their results, the authors find that fractional supersymmetry can be extended by including higher spin currents \(W^i(z)\) and \(G^i_{

Application to Superstring Theory

2021
The last chapter describes an example of solving the inverse problem of string theory as an application of deep learning. The superstring theory unifies gravity and other forces, and in recent years, the “holographic principle,” that the world governed by gravity is equivalent to the world of other forces, has been actively studied.

Nonrenormalization Theorems in Superstring Theory

Physical Review Letters, 1986
A simple proof of the nonrenormalization theorems in string theory is given. We prove (with the assumption that space-time supersymmetry is nonanomalous) that the space-time superpotential is not re-normalized by string loops. As corollaries of this result we argue that in string perturbation theory, Calabi-Yau vacua (or any other classical solution ...

Multiparticle one-loop amplitudes and S-duality in closed superstring theory

, 2013
A bstractExplicit expressions for one-loop five supergraviton scattering amplitudes in both type II superstring theories are determined by making use of the pure spinor formalism.

General signatures of superstring theories

Physical Review D, 1990
One of the most general consequences of broad classes of superstring theories is that matter supermultiplets in the four-dimensional low-energy theory should transform as singlets and doublets with canonical electric charges under the electroweak SU(2){times}U(1) group, or as singlets and fundamentals in extended groups.

SYMMETRY RESTORATION IN THE SUPERSTRING THEORY

International Journal of Modern Physics D, 2002
The grand unified gauge group G 6≡ SU (3) C × SU (3) L × SU (3) R , which results from compactification of the heterotic superstring onto a three-generation Calabi–Yau space as a maximal subgroup of E 6, contains two superfields, whose scalar components are the conjugates neutrino [Formula: see text] and the neutral Higgs N, which are singlets of the

Wormhole Solutions in Superstring Theory

International Journal of Theoretical Physics, 2000
Wormholes in a 4-dimensional superstring theory are studied. The authors deduce and solve the corresponding wormhole equations. There are given both the analytical and numerical solutions by considering three cases for the cosmological constant.

Superstring Theory: A Survey [PDF]

, 1990
Over the past few years the subject of superstring theory has exploded into a wideranging field covering many areas of modern mathematics, statistical mechanics, elementary particle physics and general relativity. It is appropriate that in this talk I should concentrate on the prospect that superstring theory may provide a unified quantum theory of all
