Supersymmetric heterotic action out of M5 brane

Abstract

Generalizing the work by Cherkis and Schwarz [1] where the bosonic part of the heterotic action was worked out with the novel introduction of the chiral bosons associated with the current algebra, we carry out the double dimensional reduction of supersymmetric M5 brane on K3 to obtain the supersymmetric action of heterotic string in 7-dimensional flat space-time. Motivated by this result, we propose the supersymmetric heterotic action in 10-dimensional flat space-time where the chiral bosons are introduced in similar way. We explicitly verify the kappa-symmetry of the proposed action.
