The Standard Electroweak Theory and Beyond
  This set of lectures provides an elementary introduction to the standard electroweak theory, followed by a detailed discussion of its experimental tests. We then consider the conceptual limitations of the Standard Model and briefly review the existing phenomenological indications of new physics. We summarize the case for a supersymmetric extension of the Standard Model. Finally we describe the present and planned searches for the Higgs and for new physics.
