### Parity Invariance For String In Twistor Space

#### Abstract

Topological string theory with twistor space as the target makes visible
some otherwise dificult to see properties of perturbative Yang–Mills
theory. But left-right symmetry, which is obvious in the standard formalism,
is highly unclear from this point of view. Here we prove that tree diagrams
computed from connected *D*-instanton configurations are parity-symmetric.
The main point in the proof also works for loop diagrams.
