The Berkovits Method for Conformally Invariant Non-linear Sigma-models on G/H
arXiv:hep-th/0602217 · doi:10.1016/j.physletb.2006.06.042
Abstract
We discuss 2-dimmensional non-linear sigma-models on the Kaehler manifold G/H in the first order formalisim. Using the Berkovits method we explicitly construct the G-symmetry currents and primaries, when G/H are irreducible. It is a variant of the Wakimoto realization of the affine Lie algebra using a particular reducible Kaehler manifold G/U(1)^r with r the rank of G.
