It was recently pointed out that the fundamental Planck mass could be close to the TeV scale with the observed weakness of gravity at long distances being due the existence of new sub-millimeter spatial dimensions. In this picture the standard model fields are localized to a (3+1)-dimensional wall or ''3-brane''. We show that in such theories there exist attractive models of inflation that occur while the size of the new dimensions are still small. We show that it is easy to produce the… 
Radion cosmology in theories with universal extra dimensions
We discuss the cosmology of models with universal extra dimensions, where the Standard Model degrees of freedom live in a (4+n)-dimensional brane, with n compact and small extra spatial dimensions.
Cosmological challenges in theories with extra dimensions and remarks on the horizon problem
We consider the cosmology that results if our observable universe is a 3-brane in a higher dimensional universe. In particular, we focus on the case where our 3-brane is located at the Z{sub 2}
The Inflationary Brane-Antibrane Universe
We show how the motion through the extra dimensions of a gas of branes and antibranes can, under certain circumstances, produce an era of inflation as seen by observers trapped on a 3-brane, with the
Primordial inflation and present-day cosmological constant from extra dimensions
Abstract A semiclassical gravitation model is outlined which makes use of the Casimir energy density of vacuum fluctuations in extra compactified dimensions to produce the present-day cosmological
Calculable corrections to brane black hole decay: The scalar case
It is a remarkable fact that in brane-world theories the true scale M * of quantum gravity may be substantially lower than the traditional Planck scale M pl , possibly approaching the TeV scale, and
The Compactification Problems of Additional Dimensions in Multidimensional Cosmological Theories
Multidimensionality of our Universe is one of the most intriguing assumption in modern physics. It follows naturally from theories unifying different fundamental interactions with gravity, e.g.
Axion model in extra dimensions with TeV scale gravity
A simple axion model is proposed in the scenario of large extra dimensions where the gravity scale is as low as 1 TeV. To obtain an intermediate-scale decay constant of the axion, the axion is
Particle physics models of inflation and curvaton scenarios
We review the particle theory origin of inflation and curvaton mechanisms for generating large scale structures and the observed temperature anisotropy in the cosmic microwave background (CMB)
The radionactive universe
In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of
Signatures of short distance physics in the cosmic microwave background
We systematically investigate the effect of short distance physics on the spectrum of temperature anistropies in the Cosmic Microwave Background produced during inflation. We present a general


New dimensions at a millimeter to a Fermi and superstrings at a TeV
Abstract Recently, a new framework for solving the hierarchy problem has been proposed which does not rely on low energy supersymmetry or technicolor. The gravitational and gauge interactions unite
The Hierarchy problem and new dimensions at a millimeter
Abstract We propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor. In this framework, the gravitational and gauge interactions become
Grand unification at intermediate mass scales through extra dimensions
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
An inflationary universe in Brans-Dicke theory: a hopeful sign of theoretical estimation of the gravitational constant
A revised model of the inflationary universe under the framework of Brans-Dicke theory is proposed. It is shown that the scale factor of the universe during the inflation varies as R approximately

A simple inflationary model characterized by a scale factor which grows like Sapprox.t/sup p/, with p a constant greater than one, which is called power-law inflation (PLI), and considers the constraints on this model coming from the requirement of solving the horizon, flatness, ''good'' reheating, and ''convenient'' perturbation-spectrum problems.
TeV scale superstring and extra dimensions
Utilizing the idea of extra large dimensions, it has been suggested that the gauge and gravity couplings unification can happen at a scale as low as 1 TeV. In this paper, we explore this
Cosmological solutions in string theories
We obtain a large class of cosmological solutions in the toroidally compactified low-energy limits of string theories in D dimensions. We consider solutions where a p-dimensional subset of the
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 within
Limits on extra dimensions in orbifold compactifications of superstrings
Abstract Perturbative breaking of supersymmetry in four-dimensional string theories predict in general the existence of new large dimensions at the TeV scale. Such dimensions can be consistent with
Inflationary Models with Exponential Potentials
Abstract In this paper we consider cosmological models containing a self-interacting scalar field possessing a potential of the form V ( φ ) = Λ exp(− λφ ). We investigate the inflationary nature of
