Abstract

The construction of heterotic string theories in d less then 10 dimensions is reviewed within the framework of the covariant lattice approach. Methods of (super) conformal field theory, necessary to calculate string scattering amplitudes, are described and applied to a 4-dimensional model. From the calculated amplitudes we extract the (point particle) field theory which reproduces these amplitudes in the limit of infinite string tension.
