TL;DR: A broad overview of the current status of proton stability in unified models of particle interactions is given which includes non-supersymmetric unification, SUSY and SUGRA unified models, unification based on extra dimensions, and string-M-theory models as mentioned in this paper.

Supersymmetric standard model spectra from RCFT orientifolds
TL;DR: In this paper, the authors present supersymmetric, tadpole-free d = 4, N = 1 orientifold vacua with a three family chiral fermion spectrum that is identical to that of the standard model.

Vacuum configurations for superstrings
TL;DR: In this paper, the authors studied candidate vacuum configurations in ten-dimensional O(32) and E 8 × E 8 supergravity and superstring theory that have unbroken N = 1 supersymmetry in four dimensions.
Journal ArticleDOI
Strings on orbifolds
TL;DR: In this article, the authors considered string propagation on the quotient of a flat torus by a discrete group and obtained an exactly soluble and more or less realistic method of string compactification.
Journal ArticleDOI
Comparison of grand unified theories with electroweak and strong coupling constants measured at LEP
TL;DR: In this paper, the DELPHI Collaboration data was used to show that in the minimal non-supersymmetric standard model with one Higgs doublet a single unification point is excluded by more than 7 standard deviations.
Journal ArticleDOI
New Heterotic String Theories in Uncompactified Dimensions < 10
TL;DR: In this article, it was shown that infinitely many heterotic string theories exist in uncompactified dimensions less than 10, that are one-loop finite (for massless external legs).
Journal ArticleDOI
Four-dimensional superstrings
TL;DR: In this article, the authors prove that modular invariance and factorization ensure the presence of a massless graviton and the correct connection between spin and statistics, and also prove that the existence of the massless spin-3/2 state ensures the absence of tachyons and vanishing of the one-loop cosmological constant.
