Abstract
We prove the existence of solution to the following -valued singular SPDE on the 2D torus : \begin{align} \label{CR} \partial_{\bar z} r = r \times \overline{r} + i \, \gamma \, {\mathscr W}, \tag{CR} \end{align} where is the Cauchy-Riemann operator on , is a real 3D white noise on whose component has zero mean over , is an -vector and .
