We continue our study of the low energy implications of $M$ theory vacua on ${G}_{2}$-manifolds, undertaken in B. S. Acharya, K. Bobkov, G. L. Kane, P. Kumar, and J. Shao, Phys. Rev. D 76, 126010 (2007); B. Acharya, K. Bobkov, G. Kane, P. Kumar, and D. Vaman, Phys. Rev. Lett. 97, 191601 (2006), where it was shown that the moduli can be stabilized and a TeV scale generated, with the Planck scale as the only dimensionful input. A well-motivated phenomenological model, the ${G}_{2}$-MSSM, can be…

Theory and phenomenology of μ in M theory

We consider a solution to the μ-problem within M theory on a G2-manifold. Our study is based upon the discrete symmetry proposed by Witten that forbids the μ-term and solves the doublet-triplet

On gauge enhancement and singular limits in G2 compactifications of M-theory

A bstractWe study the physics of singular limits of G2 compactifications of M-theory, which are necessary to obtain a compactification with non-abelian gauge symmetry or massless charged particles.

The Footprint of F-theory at the LHC

Recent work has shown that compactifications of F-theory provide a potentially attractive phenomenological scenario. The low energy characteristics of F-theory GUTs consist of a deformation away from

The String Theory Landscape

String/M theory is formulated in 10 and 11 space-time dimensions; in order to describe our universe, we must postulate that six or seven of the spatial dimensions form a small compact manifold. In

Aspects of Particle Physics and Cosmology from String/M Theory

This thesis is focused on various aspects of particle physics and cosmology from String/M theory. Assuming our universe is a solution of string/M theory, physics below the unification scale is an

An M theory solution to the strong CP-problem, and constraints on the axiverse

We give an explicit realization of the “StringAxiverse” discussed in Arvanitaki et. al [1] by extending our previous results on moduli stabilization in M theory to include axions. We extend the

Particle phenomenology from M theory inspired models

This thesis focuses on low-energy particle phenomenology arising from G2 compactifications of M theory. We construct a supersymmetric SO(10) model that can be naturally realised in this framework. An



Unification scale, proton decay, and manifolds of G(2) holonomy

Models of particle physics based on manifolds of $G_2$ holonomy are in most respects much more complicated than other string-derived models, but as we show here they do have one simplification:

Bottom-up approach to moduli dynamics in heavy gravitino scenario: Superpotential, soft terms, and sparticle mass spectrum

The physics of moduli fields is examined in the scenario where the gravitino is relatively heavy with mass of order 10 TeV, which is favored in view of the severe gravitino problem. The form of the

Explaining the Electroweak Scale and Stabilizing Moduli in M Theory

In a recent paper [1] it was shown that in M theory vacua without fluxes, all moduli are stabilized by the effective potential and a stable hierarchy is generated, consistent with standard gauge

Phenomenology of mixed modulus-anomaly mediation in fluxed string compactifications and brane models

In some string compactifications, for instance the recently proposed KKLT set-up, light moduli are stabilized by nonperturbative effects at supersymmetric AdS vacuum which is lifted to a dS vacuum by

Gaugino and Scalar Masses in the Landscape

In this letter we demonstrate the genericity of suppressed gaugino masses Ma ~ m3/2/ln (MPlanck/m3/2) in the IIB string landscape, by showing that this relation holds for D7-brane gauginos whenever

Soft SUSY breaking terms for chiral matter in IIB string compactifications

This paper develops the computation of soft supersymmetry breaking terms for chiral D7 matter fields in IIB Calabi-Yau flux compactifications with stabilised moduli. We determine explicit expressions
