I provide a pedagogical introduction to supersymmetry. The level of discussion is aimed at readers who are familiar with the Standard Model and quantum field theory, but who have had little or no prior exposure to supersymmetry. Topics covered…

These are expanded notes of lectures given at the summer school "Gif 2000" in Paris. They constitute the first part of an "Introduction to supersymmetry and supergravity" with the second part on supergravity by J.P. Derendinger to appear soon. The…

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We…

In a series of five lectures I review inflationary cosmology. I begin with a description of the initial conditions problems of the FriedmannRobertsonWalker (FRW) cosmology and then explain how inflation, an early period of accelerated expansion,…

We show that the large $N$ limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of AntideSitter spacetimes, spheres and other compact manifolds. This is shown…

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…

Twocomponent spinors are the basic ingredients for describing fermions in quantum field theory in . 3+1 spacetime dimensions. We develop and review the techniques of the twocomponent spinor formalism and provide a complete set of Feynman rules for…

The PYTHIA program can be used to generate highenergyphysics `events', i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event…

In these lecture notes we first assemble the basic ingredients of supersymmetric gauge theories (particularly N=4 superYangMills theory), supergravity, and superstring theory. Brane solutions are su, k 9990m 'rveyed. The geometry and symmetries of…

In this review article, we discuss the current status of particle dark matter, including experimental evidence and theoretical motivations. We discuss a wide array of candidates for particle dark matter, but focus on neutralinos in models of…

We suggest a means of obtaining certain Green's functions in 3+1dimensional ${\cal N} = 4$ supersymmetric YangMills theory with a large number of colors via noncritical string theory. The noncritical string theory is related to critical string…

Entanglement and (de)coherence arguably define the central issues of concern in present day quantum information theory. Entanglement being a consequence of the quantum mechanical superposition principle for composite systems, a better understanding…

Following Verlinde's recent work on the origin of gravity and the laws of Newton, we consider further the origin of the starting point of Verlinde's work and Unruh effect. Simple derivations are given for this starting point and Unruh effect with…

Recently, it has been proposed by Maldacena that large $N$ limits of certain conformal field theories in $d$ dimensions can be described in terms of supergravity (and string theory) on the product of $d+1$dimensional $AdS$ space with a compact…

The results gathered here on simple Lie algebras have been selected with attention to the needs of unified model builders who study YangMills theories based on simple, localsymmetry groups that contain as a subgroup the SUw2 × Uw1 × SUc3 symmetry…

These lectures consisted of an elementary introduction to conformal field theory, with some applications to statistical mechanical systems, and fewer to string theory. Contents: 1. Conformal theories in d dimensions 2. Conformal theories in 2…

We review the formalism of holographic renormalization. We start by discussing mathematical results on asymptotically antide Sitter spacetimes. We then outline the general method of holographic renormalization. The method is illustrated by working…

We present an update of the results presented in 1, using 3.1 pb1. In this update the analysis underwent only minor modifications due to changes in the trigger. No resonances were found in the updated sample. We improved the limits set on the…

We review the holographic correspondence between field theories and string/M\ntheory, focusing on the relation between compactifications of string/M theory\non Antide Sitter spaces and conformal field theories. We review the background\nfor this…

Advances in mathematics and physics have often occurred together. The development of Newton’s theory of mechanics and the simultaneous development of the techniques of calculus constitute a classic example of this phenomenon. However, as mathematics…
