|Abstract:||I would like to promote the Self-Dual Yang Mills Theory as a possibly|
simplest non-linear conformal field theory in 4d with no supersymmetry.
This field theory possesses UV divergences, but these do not spoil the
conformal covariance: the effect of renormalization is that the coupling
constant does not run, it is only a field renormalization which is
needed. This results in a conformal invariance of the effective action
under anomalous conformal transformations. I can give only a partial,
but hopefully convincing proof of the latter. If the time permits I will
also discuss the issue of conformal observables in this theory in
relation with twistor geometry.
