Kahler Potentials and Renormalization Group Flows in N=2 Landau-Ginzburg Models

Abstract

We examine the conditions for superconformal invariance and the specific form of the Kähler potential for a two-dimensional lagrangian model with $N=2$ supersymmetry and superpotential $g{X}^k$. Away from the superconformal point we study the renormalization group flow induced by a particular class of Kähler potentials. We find trajectories which, in the infrared, reach the fixed point with a central charge whose value is that of the $N=2$, $A_{k-1}$ minimal model.
