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
Macroscopic strings as heavy quarks in large N gauge theory and Antide Sitter supergravity
 PHYS. J. C22
"... Maldacena has put forward large N correspondence between superconformal field theories on the brane and antide Sitter supergravity in spacetime. We study some aspects of the correspondence between N = 4 superconformal gauge theory on D3brane and maximal supergravity on adS5 × S5 by introducing mac ..."

Integrable Hamiltonian for classical strings on ADS5 × S 5
, 2004
"... We find the Hamiltonian for physical excitations of the classical bosonic string propagating in the AdS5 × S5 spacetime. The Hamiltonian is obtained in a socalled uniform gauge which is related to the static gauge by a 2d duality transformation. The Hamiltonian is of the Nambu type and depends on ..."

Phenomenology on a Slice of AdS5 × M δ Spacetime ∗
, 2003
"... We study the phenomenology resulting from backgrounds of the form AdS5 × Mδ, where Mδ denotes a generic manifold of dimension δ ≥ 1, and AdS5 is the slice of 5dimensional antide Sitter space which generates the hierarchy in the RandallSundrum (RS) model. The δ additional dimensions may be require ..."

‘AdS5 ’ Geometry Beyond Spacetime and 4D Noncommutative Spacetime
, 2008
"... Abstract: We discuss a 4D noncommutative spacetime as suggested by the version of quantum (deformed) relativity which provides a classical geometry picture as an ‘AdS5’. The 4D noncommutative spacetime is more like a part of a phase space description, in accordance with the quantum notion – quantu ..."

Properties of branes in curved spacetimes
, 2003
"... A generic property of curved manifolds is the existence of focal points. We show that branes located at focal points of the geometry satisfy special properties. Examples of backgrounds to which our discussion applies are AdSm×S n and plane wave backgrounds. As an example, we show that a pair of AdS2 ..."

2 branes located at the north and south pole of the S 5 in AdS5×S 5 are half supersymmetric and that they are dual to a twomonopole solution of N = 4 SU(N) SYM theory. Our second example involves spacelike branes in the (Lorentzian) plane wave. We develop a modified lightcone gauge for the open
Brane SpaceTime and Cosmology

"... I reconsider the cosmology of a 3brane universe imbedded in a fivedimensional antide Sitter space AdS5 with a cosmological constant and show that the resulting Friedmann equations for this system are identical to those standard obtained in 4D FRW spacetime in the presence of an additional densit ..."

A new doublescaling limit of N = 4 super YangMills theory and PPwave strings, Nucl. Phys. B643

According to the AdS/CFT correspondence, the holographic dual of superstring theory on that background should be the analogous limit of N = 4 supersymmetric YangMills theory. In thi ..."

Chiral Anomaly in Contorted Spacetimes
, 1997
"... The Dirac equation in RiemannCartan spacetimes with torsion is reconsidered. As is wellknown, only the axial covector torsion A, a oneform, couples to massive Dirac fields. Using diagrammatic techniques, we show that besides the familiar Riemannian term only the Pontrjagin type fourform dAdA d ..."
