Angles and Daemons: Spin Correlations at the LHC

The Large Hadron Collider has recently started collecting data, opening a new energyregime. This will allow us to probe further than ever before many of the current mysteries of thefield. New physics beyond the Standard Model, the field’s current paradigm, could manifestitself via new particles. In addition, the Higgs boson, hypothesized as a consequence ofelectroweak symmetry breaking, remains undiscovered. At the time of discovery, the propertiesof such particles will be unknown. In order to understand the nature of any new physics, itwill be important to understand the properties of that new particle. Methods are presented formeasuring its spin, parity and coupling to the Standard Model particles. These methods areimplemented at the Compact Muon Solenoid experiment and an analysis is presented with thedata collected during 2010 and 2011 running at the Large Hadron Collider. An application ofthese techniques is used to make a measurement of the weak mixing angle. A current statusof the search for the Higgs boson is also presented.
