Title: "Renormalization and the Hierarchy Problem"
Abstract: We reconsider renormalization of observables, not bare parameters, in quantum field theory. We review two examples and see how divergences in the observables cancel inclduing the quadratic: the vacuum polarization and the top-quark correction to the Higgs mass. The result does not depend on the regularization scheme: simple cutoff and dimensional regularization give the same result.
