SuperPoincaré invariant superstring field theory
Abstract
Using the topological techniques developed in an earlier paper with Vafa, a field theory action is constructed for any open string with critical N = 2 worldsheet superconformal invariance. Instead of the ChemSimonslike action found by Witten, this action resembles that of a WessZuminoWitten model. For the N = 2 string which describes (2,2) selfdual YangMills, the string field generalizes the scalar field of Yang. As was shown in recent papers, an N = 2 string can also be used to describe the GreenSchwarz superstring in a CalabiYau background. In this case, one needs three types of string fields which generalize the real superfield of the superYangMills prepotential, and the chiral and antichiral superfields of the CalabiYau scalar multiplet. The resulting field theory action for the open superstring in a CalabiYau background has the advantages over the standard RNS action that it is manifestly SO(3,1) superPoincaré invariant and does not require contact terms to remove treelevel divergences.
