Extra spacetime dimensions and unification
, 1998
"... We study the effects of extra spacetime dimensions at intermediate mass scales, as expected in string theories with largeradius compactifications, and focus on the gauge and Yukawa couplings within the Minimal Supersymmetric Standard Model. We find that extra spacetime dimensions naturally lead to ..."

Probing Extra Spacetime Dimensions at the Tevatron
"... Theories with extra spacetime dimensions aiming at resolving the hierarchy problem have recently been developed. These scenarios have provided exciting new grounds for experimental probes. A review of the searches conducted at the Tevatron in this framework during its first running phase and the pro ..."

(3 + 1) of Large Spacetime Dimensions
, 2006
"... We assume that our universe originated from highly excited and interacting strings with coupling constant gs = O(1). Fluctuations of spacetime geometry are large in such strings and the physics dictating the emergence of a final spacetime configuration is not known. We propose that, nevertheless, it ..."

and with 6 – dimensional compact space of size ls; in particular, the number of large spacetime dimensions is d = 3 + 1. Such an universe may evolve subsequently into our universe, perhaps as in Banks – Fischler scenario.
COSMOLOGICAL MODELS IN TWO SPACETIME DIMENSIONS
, 1992
"... Various physical properties of cosmological models in (1+1) dimensions are investigated. We demonstrate how a hot big bang and a hot big crunch can arise in some models. In particular, we examine why particle horizons do not occur in matter and radiation models. We also discuss under what circumstan ..."

. Gravitational theory in two spacetime dimensions continues to provide theorists with an interesting “laboratory ” for exploring the foundations of classical and quantum gravity. The reduction in the number of degrees of freedom markedly reduces the complexity of a system of (3 + 1)dimensional gravity
Gravitational kinks in two spacetime dimensions
, 1996
"... Abstract. The properties of gravitational kinks are studied within some simple models of two dimensional gravity. In spacetimes of cylindrical topology we prove the existence of kinks of constant curvature with arbitrary kink numbers. In R 1 × R 1 spacetimes m = 1 kink solutions of the equation R = ..."

A large mass hierarchy from a small extra dimension
, 1999
"... We propose a new higherdimensional mechanism for solving the hierarchy problem. The weak scale is generated from a large scale of order the Planck scale through an exponential hierarchy. However, this exponential arises not from gauge interactions but from the background metric (which is a slice of ..."

of AdS5 spacetime). This mechanism relies on the existence of only a single additional dimension. We demonstrate a simple explicit example of this mechanism with two threebranes, one of which contains the Standard Model fields. The experimental consequences of this scenario are new and dramatic
Particle Physics Probes Of Extra Spacetime Dimensions
, 2002
"... ABSTRACT: The possibility that spacetime is extended beyond the familiar 3+1dimensions has intrigued physicists for a century. Indeed, the consequences of a dimensionally richer spacetime would be profound. Recently, new theories with higher dimensional spacetimes have been developed to resolve the ..."

Static BPS ’monopoles ’ in all even spacetime dimensions
, 2005
"... Two families of SO(2n) Higgs models in 2n dimensional spacetime are presented. One family arises from the dimensional reduction of higher dimensional YangMills systems while the construction of the other one is ad hoc, the n = 2 member of each family coinciding with the usual SU(2) YangMills–Higgs ..."

Charged Rotating Black Hole in Three Spacetime Dimensions

"... The generalization of the black hole in threedimensional spacetime to include an electric charge Q in addition to the mass M and the angular momentum J is given. The field equations are first solved explicitly when Q is small and the general form of the field at large distances is established. The ..."
