These five lectures give an elementary introduction to perturbative superstring theory, superstring phenomenology, and the fermionic construction of perturbative string models. These lectures assume no prior knowledge of string theory.

After a brief introduction to chiral perturbation theory, the effective field theory of the standard model at low energies, two recent applications are reviewed: elastic pion–pion scattering to two– loop accuracy and the complete renormalized pion–nucleon Lagrangian to O(p 3) in the chiral expansion.

We present two different aspects of the anomalies in quantum field theory. One is the dispersion relation aspect, the other is differential geometry where we derive the Stora–Zumino chain of descent equations. *) Lecture given at the conference " QCD 94 " , Montpellier, France.
