Parity Invariance For String In Twistor Space
Parity Invariance For String In Twistor Space
Topological string theory with twistor space as the target makes visible some otherwise difficult 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 paritysymmetric.The …
