The quantisation of string theories on curved backgrounds is a notoriously difficult task.

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 computation of the finitevolume spectrum then requires to introduce a Wickrotated worldsheet model, the socalled mirror model. This is quite nontrivial if the original worldsheet theory is not relativistic. This thesis will perturbatively compute the twoparticle into twoparticle scattering processes and some production processes for the "mirror" of a worldsheet model.File  Dimensione  Formato
