Alternative N = (4, 0) superstring and σmodels
Abstract
We present an alternative N = (4, 0) superstring theory, with a field content different from that of previouslyknown N = (4, 0) superstring theories. This theory is presented as a nonlinear σmodel on the coset {SU(n,1)}/{SU(n)} ⊗ U(1) as the target spacetime with torsion, which is coupled to N = (4,0) worldsheet superconformal gravity. Our result indicates that the target spacetime for the N = 4 superstring theory does not necessarily have to be a hyperKähler or quaternionic Kähler manifold.
