This contribution, aimed mostly at experimental particle physicists, reviews some of the main ideas and results of String Theory in a non-technical language. It originates from the talks presented by the authors at the Electro-Weak session of the 2002 Moriond Meeting, here merged in an attempt to provide a more complete and concise view of the subject. 

Aspects of branes in (heterotic) M-theory

First a short introduction to principles and some recent developments in string theory is given. In a second part the effective action for fiveas well as four-dimensional heterotic M-theory in the

On the Geometry of Higher Spin Gauge Fields

We review a recent construction of the free field equations for totally symmetric tensors and tensor-spinors that exhibits the corresponding linearized geometry. These equations are not local for all

Metric-like Lagrangian Formulations for Higher-Spin Fields of Mixed Symmetry

We review the structure of local Lagrangians and field equations for free bosonic and fermionic gauge fields of mixed symmetry in flat space. These are first presented in a constrained setting

Three-charge supertubes in a rotating black hole background

The low velocity scattering of a D0-F1 supertube in the background of a BMPV black hole has been considered by Marolf and Virmani. Here we extend the analysis to the case of the D0-D4-F1 supertube of

Teoria delle Stringhe

Lectures on string theory

This book provides an introduction to string theory, at present one of the fastest-growing areas in theoretical high-energy physics. It introduces modern techniques and concepts, such as conformal

Introduction to Superstring Theory

These four lectures, addressed to an audience of graduate students in experimental high energy physics, survey some of the basic concepts in string theory. The purpose is to convey a general sense of

Theory and phenomenology of type I strings and M-theory

The physical motivations and the basic construction rules for type I strings and M-theory compactifications are reviewed in the light of recent developments. The first part of this review contains

Scales of string theory

I review the arguments in favour of/against the traditional hypothesis that the Planck, string and compactification scales are all within a couple of orders of magnitude of each other. I explain how

The Cosmological Constant from the Viewpoint of String Theory

The mystery of the cosmological constant is probably the most pressing obstacle to significantly improving the models of elementary particle physics derived from string theory. The problem arises

An Introduction to the Theory of Dual Models and Strings

The theory of a free string is first presented classically and quantum mechanically both in a covariant and a nonexplicitly covariant treatment. Then the concepts and techniques obtained from the

New Perspectives in String Phenomenology from Dualities

After a review of some topics concerning the phenomenological applications of perturbative string theory, I discuss to what extent all of it is affected by the recent developements in string

Monopoles, Instantons and Confinement

We review the physics of topological objects in QCD. Topics include: solitons, vortices, magnetic monopoles, instantons, (effective theories of) confinement.

New Perspectives on the Quest for Unification

Synthesizing older ideas about the 1/N expansion in gauge theory, the quantum mechanics of black holes, and quantum field theory in Anti de Sitter space, a new correspondence between gauge theory and
