摘要
CERN's Large Hadron Collider (LHC), the world's most powerful particle accelerator, has begun collecting data at high energies. Soon we will be able to address two of the most exciting and fundamental questions about nature: what is the mechanism of electroweak symmetry breaking, and what is the identity of dark matter. I will begin by explaining these issues. Then I will describe how these questions can be answered in the challenging environment of the LHC, in the process introducing new techniques for the treatment of jets and jet substructure. Finally I will describe the production and measurement of dark matter at the LHC, with a brief discussion of some recently developed models and signal classes.
