@article{Barbn1996ComplexWS, title={Complex world sheets from N=2 strings}, author={J. L. F. Barb{\'o}n and Miguel Angel Vazquez-Mozo}, journal={Nuclear Physics}, year={1996}, volume={475}, pages={244-270} }

Abstract We study some properties of target space strings constructed from (2,1) heterotic strings. We argue that world-sheet complexification is a general property of the bosonic sector of such target world-sheets. We give a target space interpretation of this fact and relate it to the non-gaussian nature of free String Field Theory. We provide several one-loop calculations supporting the stringy construction of critical world-sheets in terms of (2,1) models. Using finite-temperature boundary…
