The Large Hadron Collider (LHC) is currently the world's premier facility for the study of high-energy particle physics. The goal of the Compact Muon Solenoid (CMS) experiment at the LHC is to search for new phenomena in particle physics at the TeV scale. One of the mysteries that data from CMS may solve is the origin of dark matter. It is hoped that dark matter particles will be produced in the proton-proton collisions of the LHC, either by themselves or along with other new particles. This would allow the laws that govern dark matter to be explored. Collisions containing dark matter particles will pose new challenges for collider physics, necessitating the development of new methods to deal with these problems. One class of methods for addressing these problems is kinematic endpoint variables such as MT2 and MCT. A great deal of theoretical work has been done in developing these methods, but they have seldom been applied in experiment. We apply these methods to data taken with CMS to address two problems: mass measurement in underconstrained events and searches for new physics. In doing so, we also provide a new measurement of the top-quark mass and search for new physics in events with two leptons and a momentum imbalance.

This book contains write-ups of lectures from a summer school for advanced graduate students in elementary particle physics. In the first lecture, Scott Willenbrock gives an overview of the standard model of particle physics. This is followed by reviews of specific areas of standard model physics: precision electroweak analysis by James Wells, quantum chromodynamics and jets by George Sterman, and heavy quark effective field by Matthias Neubert. Developments in neutrino physics are discussed by Andr de Gouvea and the theory behind the Higgs boson is addressed by Laura Reina. Collider phenomenology from both experimental and theoretical perspectives are highlighted by Heidi Schellman and Tao Han. A brief survey of dynamical electroweak symmetry breaking is provided by R Sekhar Chivukula and Elizabeth H Simmons. Martin Schmaltz covers the recent proposals for ?little? Higgs theories. Markus Luty describes what is needed to make supersymmetric theories realistic by breaking supersymmetry. There is an entire series of lectures by Raman Sundrum, Graham Kribs, and Csaba Cs ki on extra dimensions. Finally, Keith Olive completes the book with a review of astrophysics.

Dark matter is a frequently discussed topic in contemporary particle physics. Written strictly in the language of particle physics and quantum field theory, these course-based lecture notes focus on a set of standard calculations that students need in order to understand weakly interacting dark matter candidates. After introducing some general features of these dark matter agents and their main competitors, the Higgs portal scalar and supersymmetric neutralinos are introduced as our default models. In turn, this serves as a basis for exploring four experimental aspects: the dark matter relic density extracted from the cosmic microwave background; indirect detection including the Fermi galactic center excess; direct detection; and collider searches. Alternative approaches, like an effective theory of dark matter and simplified models, naturally follow from the discussions of these four experimental directions.
