Explicit Derivation of New Hyper-Kahler metric

Abstract

Using the harmonic superspace techniques in D=2 N=4, we present an explicit derivation of a new hyper-Kahler metric associated to the Toda like self interaction $H^{4+}(\omega ,u)=(\frac{{\xi }^{++}}{\lambda }{)}^2\exp (2\lambda \omega )$. Some important features are also discussed.
