That method is preferred to dimensional regularization when considering chiral phenomena.
This physicist developed a regularization method of introducing a spectrum of auxiliary particles and taking the limit as their masses go to infinity with Felix Villars. That method is preferred to dimensional regularization when considering chiral phenomena. He proved the result that symmetry or antisymmetry under exchange corresponded to (*) integer or half-integer spin, the spin-statistics theorem. His best-known result creates the "degeneracy pressure" that keeps sufficiently low mass white dwarfs from collapsing. For 10 points, name this physicist who discovered that no two fermions can occupy the same quantum state, his namesake exclusion principle.
