Abstract

We apply Kadanoff's theory of marginal deformations of conformal field theories to twistfield deformations of Z₂ orbifold models in K3 moduli space. These deformations lead away from the Z₂ orbifold sub-moduli-space and hence help to explore conformal field theories which have not yet been understood. In particular, we calculate the deformation of the conformal dimensions of vertex operators for p²<1 in second order perturbation theory.
