Silicon strip detector qualification for the CMS experiment
The Compact Muon Solenoid (CMS) is one of the four experiments being installed at the Large Hadron Collider (LHC) which is located at the european organization for nuclear research CERN in Geneva. This proton-proton collider will explore a new energy regime of up to 14 TeV center-of-mass energy. To …

Observation of electroweak W±W± JJ production with the CMS experiment
The CMS detector at the CERN LHC is sensitive to Standard Model predictions regarding the production of two W bosons with the same charge accompanied by two jets. In particular, when these particles are produced in a topology where the jets have a high invariant mass and are largely separated in …

Studies of Jet Modification in Heavy Ion Collisions with the CMS Experiment
In the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC), lead ions are collided at ultra-relativistic velocities to produce Quark-Gluon Plasma (QGP), a state of matter where quarks and gluons are deconfined and move collectively. Jets are produced in high-momentum transfer …
