Abstract
The quantisation of string theories on curved backgrounds is a notoriously difficult task. One approach that is proving very powerful when string nonlinear sigma model is integrable is to bootstrap a factorised S matrix on the twodimensional string worldsheet. The symmetrybased bootstrap approach must however be checked by perturbative computations. This thesis will perturbatively verify the factorisation of the threeparticle into threeparticle scattering processes into a sequence of twointotwo processes. Prerequisites for the thesis are a working knowledge of quantum field theory.File  Dimensione  Formato
