CERN-TH/97-218hep-th/9709062INTRODUCTION TO SUPERSTRING THEORYElias Kiritsis THEORY Division, CERN,CH-1211, Geneva 23, SWITZERLANDAbstractIn these lecture notes, an INTRODUCTION to SUPERSTRING THEORY is presented. Classi-cal strings, covariant and light-cone quantization, supersymmetric strings, anomalycancelation, compacti cation, T-duality, supersymmetry breaking, and thresholdcorrections to low-energy couplings are discussed. A brief INTRODUCTION to non-perturbative duality symmetries is also presented at the Catholic University of Leuven andat the University of Padova during the academic year be published by Leuven University 1997 e-mail: Introduction22 Historical perspective33 Classical string Relativisticstrings ...............................

1 Introduction String theory has been the leading candidate over the past years for a theory that consis-tently uni es all fundamental forces of nature, including gravity. In a sense, the theory predicts gravity and gauge symmetry around flat space. Moreover, the theory is UV- nite.
