The LHC search for the physics behind the Standard Model

I will start with an overview of some of the most important open
questions in particle physics. Some of these issues require, and other
strongly suggest, the existence of yet-unknown particles and fields in
nature. I will argue that the Standard Model is just an effective
partial description of a more fundamental theory that stands behind it
and is yet to be discovered. I will then focus on the puzzle of the
electroweak-Planck hierarchy, where hints about the underlying
mechanism are likely to be within the reach of the Large Hadron
Collider (LHC) at CERN. I will also mention my own work, which
involves analyzing the results of LHC searches and proposing new
search directions for the physics behind the electroweak-Planck
hierarchy and other new phenomena that may be accessible at the LHC.
