Supersymmetric deformation of the CP^1 model and its conformal limit

(Théorie des Interactions Fondamentales)


I will show that the supersymmetric deformed CP^1 sigma model -- the supersymmetric generalization of the Fateev-Onofri-Zamolodchikov model -- may be cast in the form of a generalized Gross-Neveu model. The beta function may be easily calculated in this formalism, showing that in the UV the theory flows to the super-Thirring model. I will prove that the latter is equivalent to a sigma model with target space the cylinder by explicitly calculating correlation functions of elementary fields on both sides.
