Abstract
Motivated by applications of twisted current algebras in description of the entropy of black hole, we investigate the simplest twisted current algebra . Free field representation of the twisted algebra and the corresponding twisted Sugawara energy-momentum tensor are obtained by using three pairs and two scalar fields. Primary fields and two screening currents of the first kind are presented.
