Abstract
By considering N = 2 string amplitudes we determine the (2 + 2)-dimensional target space action for the physical degrees of freedom: self-dual gravity and self-dual Yang-Mills, together with their respective infinite towers of higher-spin inequivalent picture states. Novel 'stringy' couplings amongst these fields are essential ingredients of an action principle for the effective target space field theory. We discuss the covariant description of this theory in terms of self-dual fields on a hyperspace parametrised by the target space coordinate and a commuting chiral spinor.

N1 - Funding Information: We have recently presented a covariant description of the physical degrees of freedom of the N = 2 open string in terms of a self-dual Yang-Mills theory on a hyperspace parametrised by the coordinates of the (2 + 2)-dimensional target space x ±a together with a commuting chiral spinor r/± \[1 \]. The infinite tower of massless string degrees of freedom, corresponding to the inequivalent pictures (spinor ghost vacua) of this string \[2\], are compactly represented by a hyperspace generalisation of the prepotential * Supported in part by the Deutsche Forschungsgemeinschaft; grant LE-838/5-2. l E-mail: devchand@mis.mpg.de 2 http: //www.itp.uni-hannover.de/-lechtenf 0550-3213/99/$ - see frontmatter (~) 1999 Elsevier Science B.V.
