Description
One of the most preplexing predictions of Chiral Perturbation Theory is the negative electric polarizability of the neutral pion. We revisit this problem and argue that in an ultraviolet-complete calculation the polarizabilty is positive. A novel light-front QCD calculation will be presented, corroborating this point.
