With the Large Hadron Collider (LHC) just completing its first three-year run and,
there has been a great interest from the world's media and scientists with its discovery of a Higgs-like particle. This talk aims to give a simple introduction to the exciting physics currently taking place at the LHC, and explain why we, particle physicist, are very excited about the LHC, and what we expect to see at the LHC from our theoretical understanding. The standard model of particle physics will be introduced, along with its success and puzzle. The necessity of finding new physics, and in particular, existence of Higgs mechanism of the electroweak symmetry breaking will be discussed from a simple quantum mechanics reason. The origin of mass of the elementary particles will be discussed with the Higgs boson. And, a naturalness problem associated with the Higgs will be discussed. Then, several theoretical models to solve the naturalness problem will be discussed. Finally, what we hope to find in the next LHC run starting in 2015 with its center-of-mass energy increased to 13 tera-electron volt will be discussed.
