CONFORMAL FIELD-THEORY OF A ROTATING DYON

A conformal field theory representing a four-dimensional classical solution of heterotic string theory is presented. The few-energy limit of this solution has U(1) electric and magnetic charges, and also nontrivial axion and dilaton fields. The low-energy metric contains mass, NUT, and rotation parameters. We demonstrate that this solution corresponds to part of an extremal limit of the Kerr-Taub-NUT dyon solution, This limit displays interesting ''remnant'' behavior in that asymptotically far away from the dyon the angular momentum vanishes, but far down the infinite throat in the neighborhood of the horizon (described by our CFT) there is a nonzero angular velocity. A further natural generalization of the CFT to include an additional parameter is presented, but the full physical interpretation of its role in the resulting low energy solution is unclear.
