Over the past three years our views on how the standard model of particle theory could be embedded into string theory have changed dramatically. The heterotic string is no longer the only possibility for such an embedding and other perturbative (or non-perturbative) corners of M-theory, like type I or II strings, now seem possible. It has also been realized that the string scale Ms is not necessarily close to the Planck scale and could be much smaller, of the order of the intermediate scale (MW… 

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

Intersecting D-brane Models

This thesis is devoted to the study of a class of constructions based on Superstring Theory, baptized in the literature as Intersecting Brane Worlds. In particular we explore several issues regarding

Introduction to string theory and string compactifications

Basics of some topics on perturbative and non-perturbative string theory are reviewed. After a mathematical survey of the Standard Model of particle physics and GUTs, the bosonic string kinematics

In quest of "just" the Standard Model on D-branes at a singularity

In this note we explore the possibility of obtaining gauge bosons and fermionic spectrum as close as possible to the Standard Model content, by placing D3-branes at a N orbifold-like singularity in

Some phenomenology of intersecting D-brane models

We present some phenomenology of a new class of intersecting D-brane models. Soft SUSY breaking terms for these models are calculated in the complex structure (u)-moduli dominant SUSY breaking

Topics on Strings, Branes and Calabi-Yau compactifications

Basics of some topics on perturbative and non-perturbative string theory are reviewed. After a mathematical survey of the Standard Model of particle physics and GUTs, the bosonic string kinematics

The SQCD vacuum coupled to supergravity and string theory moduli

We calculate the scalar potential of supersymmetric QCD (in the regime Nf < Nc) coupled to = 1 supergravity with moduli-dependent gauge kinetic function and masses. The gauge dynamics are described

Exact Standard Model Compactifications from Intersecting Branes

We construct six stack D6-brane vacua (non-supersymmetric) that have at low energy exactly the standard model (with right handed neutrinos). The construction is based on D6-branes intersecting at

TeV Scale Strings and Scattering Amplitudes at the LHC

We study aspects of TeV string scale models of intersecting D-branes. The gauge bosons arise from strings ending on stacks of D-branes, whereas chiral matter arises from strings stretched between

SUSY Quivers, Intersecting Branes and the Modest Hierarchy Problem

We present a class of chiral non-supersymmetric D = 4 field theories in which quadratic divergences appear only at two loops. They may be depicted as ``SUSY quivers'' in which the nodes represent a

Non-perturbative vacua in heterotic M-theory

We present a class of N = 1 supersymmetric `standard' models of particle physics, derived directly from heterotic M-theory, that contain three families of chiral quarks and leptons coupled to the

Mass scales, supersymmetry breaking and open strings

We review physical motivations and possible realizations of string vacua with large internal volume and/or low string scale and discuss the issue of supersymmetry breaking. In particular, we describe

Anomalous U(1)'s and Proton Stability in Brane Models

We consider the most general generation-independent U(1) gauge symmetry consistent with the presence of Yukawa couplings for all quarks and leptons in the SUSY version of the Standard Model. This
