String models with twisted currents
Physical Review D, 1986We consider bosonic string models with non-Abelian gauge excitations, whose Lie-algebra-valued currents are ''twisted'' by nontrivial automorphisms. The twisted models have the same critical dimension as the corresponding untwisted models; however, their respective spectra are radically different.

The supersymmetric standard model and strings
Nuclear Physics B - Proceedings Supplements, 1994Abstract I discuss recent work in connection with the SUSY versions of the standard model which might be obtained from 4-dimensional string theories. In particular, it is shown how one can obtain definite predictions for the structure of SUSY-breaking soft terms in moduli/dilaton dominated SUSY-breaking schemes.

STRING MODEL BUILDING AT LOW STRING SCALE
String Phenomenology, 2003We consider string model building in scenarios in which the fundamental string scale is low compared to the four-dimensional Planck scale. We present a consistent string theory model which gives a conservative extension of the Standard Model, consisting of a D3-brane at a simple orbifold singularity.

String Theory, String Model-Building, and String Phenomenology — A Practical Introduction
2008This is the written version of an introductory self-contained course on string model-building and string phenomenology given at the 2006 TASI summer school. No prior knowledge of string theory is assumed. The goal is to provide a practical, “how-to” manual on string theory, string model-building, and string phenomenology with a minimum of mathematics ...
