Abstract One of the drawbacks of conventional grand unification scenarios has been that the unification scale is too high to permit direct exploration. In this paper, we show that the unification scale can be significantly lowered (perhaps even to the TeV scale) through the appearance of extra space-time dimensions. Such extra dimensions are a natural consequence of string theories with large-radius compactifications. We show that extra space-time dimensions naturally lead to gauge coupling… Expand
Power-like threshold corrections to gauge unification in extra dimensions
Abstract One of the much-debated novel features of theories with extra dimensions is the presence of power-like loop corrections to gauge coupling unification, which have the potential of allowing aExpand
TeV scale unification in four dimensions versus extra dimensions
Abstract The gauge coupling constant unification at the low ( O (TeV)) scale can be obtained just in four dimensions, without the help of the power like renormalization group evolution in extraExpand
Effect of extra dimensions on gauge coupling unification
Abstract The effects of extra dimensions on gauge coupling unification is studied. We start with a comparison between power law running of the gauge couplings in models with extra dimensions andExpand
Grand Unification in Higher Dimensions
We have recently proposed an alternative picture for the physics at the scale of gauge coupling unification, where the unified symmetry is realized in higher dimensions but is broken locally by aExpand
Probing TeV-scale gauge unification by hadronic collisions
Grand unified theories (GUTs) and extra dimensions are potential ingredients of the new physics that may resolve various outstanding problems of the Standard Model. If the inverse size of (one of)Expand
Gauge Unification in Extra Dimensions: Power Corrections vs. Higher-Dimension Operators
Abstract Power-like loop corrections to gauge couplings are a generic feature of higher-dimensional field theories. In supersymmetric grand unified theories in d = 5 dimensions, such correctionsExpand
Grand unification in RS1
Abstract We study unification in the Randall–Sundrum scenario for solving the hierarchy problem, with gauge fields and fermions in the bulk. We calculate the one-loop corrected low-energy effectiveExpand
Aspects of extra dimensional supersymmetric unified theories
Although one does not know (yet) which phenomenon unitarizes WLWL scattering at the TeV scale, indirect data currently favors the Higgs boson. Since such a scalar particle is susceptible to become asExpand
Dark matter and collider phenomenology of universal extra dimensions
Abstract We review the phenomenology of models with flat, compactified extra dimensions where all of the Standard Model fields are allowed to propagate in the bulk, known as Universal ExtraExpand
Gauge coupling unification with extra dimensions and gravitational scale effects
Abstract We study gauge coupling unification in the presence of extra dimensions compactified at a few TeV. Achieving unification requires a large number of gauge boson Kaluza–Klein excitationsExpand


Extra Spacetime Dimensions and Unification
We study the effects of extra spacetime dimensions at intermediate mass scales, as expected in string theories with large-radius compactifications, and focus on the gauge and Yukawa couplings withinExpand
Couplings and scales in strongly coupled heterotic string theory
If nature is described by string theory, and if the compactification radius is large (as suggested by the unification of couplings), then the theory is in a regime best described by the low energyExpand
Strong Unification
We investigate the possibility that unification occurs at strong coupling. We show that, despite the fact the couplings pass through a strong coupling regime, accurate predictions for their lowExpand
Coupling Constant Unification in Extended SUSY Models
Abstract The unification of gauge coupling constants in the minimal supersymmetric model (MSSM) is unaffected at the one-loop level by the inclusion of additional mass-degenerate SU(5) multiplets.Expand

The problems of unification-mismatch and low α3: A solution with light vector-like matter
Abstract The commonly accepted notion of a weak unified coupling αX ≈ 0.04, based on the assumption of the MSSM-spectrum, is questioned. It is suggested that the four-dimensional unified stringExpand
Supersymmetry breaking in M theory and gaugino condensation
Abstract We argue that supersymmetry breaking by gaugino condensation in the strongly coupled heterotic string can be described by an analogue of Scherk-Schwarz compactification on the eleventhExpand
Low-energy signatures of semiperturbative unification
We consider the low-energy signatures of, and high-energy motivations for, scenarios of semiperturbative gauge coupling unification. Such scenarios can leave striking imprints on the low-energyExpand
