TLDR
In this article, it is confirmed that new physics outside the standard model (SM) is required to obtain unification of the electroweak and strong forces, which could come from the minimal supersymmetric extension of the SM, which provides unification consistent with the present limits on the proton lifetime.About:

Proton stability in grand unified theories, in strings and in branes
Pran Nath,Pavel Fileviez Pérez +1 more
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.

String theory and the path to unification: A Review of recent developments
TL;DR: In this paper, the authors provide an overview of the different approaches that have been taken in recent years towards reconciling these two scales, and outline some of the major recent developments in each.

Journal ArticleDOI
Cosmic strings and superstrings
TL;DR: Cosmic strings are predicted by many field-theory models, and may have been formed at a symmetry-breaking transition early in the history of the universe, such as that associated with grand unification.
Journal ArticleDOI
QED coupled to QEG
Ulrich Harst,Martin Reuter +1 more
TL;DR: In this paper, the authors discuss the non-perturbative renormalization group flow of QED coupled to QEG and explore the possibilities for defining its continuum limit at a fixed point that would lead to a non-trivial, i.e. interacting field theory.

Unity of All Elementary Particle Forces
Howard Georgi,Sheldon L. Glashow +1 more
TL;DR: In this paper, strong, electromagnetic, and weak forces are conjectured to arise from a single fundamental interaction based on the gauge group SU(5), which is known as SU(4).
Journal ArticleDOI
Dynamical Breaking of Supersymmetry
TL;DR: In this article, general conditions for dynamical supersymmetry breaking are discussed and examples are given (in 0 + 1 and 2 + 1 dimensions) in which such a program in four dimensions is possible.
Journal ArticleDOI
Supersymmetry, Supergravity and Particle Physics
TL;DR: In this paper, a short introduction to N = 1 supersymmetry and supergravity and review the attempts to construct models in which the breakdown scale of the weak interactions is related to supersymmetric breaking is given.

The Search for Supersymmetry: Probing Physics Beyond the Standard Model
TL;DR: A survey of methods by which supersymmetry could be observed in experiments at present and future accelerators can be found in this paper, with considerable emphasis on pedagogical completeness.

Supergauge Transformations in Four-Dimensions
Julius Wess,Bruno Zumino +1 more
TL;DR: In this article, supergauge transformations are defined in four space-time dimensions and their commutators are shown to generate γ5 transformations and conformal transformations, respectively.
