# N=(2,2) supersymmetry in two-dimensional Euclidean space

Can anyone describe (or give a reference for) the 2d superspace formulation of N=(2,2) SUSY in Euclidean signature?

I'm reading Hori's excellent introduction to QFT in the book 'Mirror symmetry', and my question is basically Ex. 12.1.1. page 273. What I imagine the answer is is a super version of the usual story of differential forms on complex manifolds, i.e. we complexify, find square roots of the $\partial_z$ and $\partial_{\bar{z}}$ operators, then find a subalgebra of 'chiral' fields analogous to the subalgebra of holomorphic forms.

• I'm not sure if I understand your question, but have you looked at the article by Deligne and Morgan in the "Quantum Fields and Strings" book? – Kevin H. Lin Dec 9 '09 at 17:18

You imagine well. Hori is talking about $\mathbb{R}^{2|2}$, which is arguably the simplest super Riemann surface.
