  These lectures provide a self-contained introduction to the essential aspects
of non-supersymmetric beyond the Standard Model (BSM) physics for beginning
graduate students who are already familiar with quantum field theory. After a
detailed review of the physical meaning of the hierarchy problem, we introduce
the key ingredients of the physics of Goldstone bosons necessary for many
non-supersymmetric new physics models. Next we discuss the concept of
collective symmetry breaking and present the main elements leading to little
Higgs/composite Higgs models. We then turn to extra dimensional theories. After
covering some of the basics of extra dimensional physics, we describe warped
extra dimensions and explain how the AdS/CFT correspondence leads to realistic
RS models and the holographic minimal composite Higgs model.
