Discovery of the Higgs boson by the CMS experiment
Graduate student seminar (GSS)
12:30 pm
Jorgensen Hall Room: 145
***Note that this event is open to graduate students only***
Presenter: Joaquin E Siado Castaneda
Abstract
In July of 2012 the Compact Muon Solenoid (CMS) and A Large Toroidal LHC apparatus (ATLAS) experiments announced the observation of a new particle consistent with the Higgs boson predicted by the standard model of particles physics. An excess of events was observed above the expected background with a local significance of 5.0 standard deviations, at a mass near 125 GeV, signalling the production of a new particle.
This talk* features a review of the original papers published by the CMS experiment. A historical context to particle physics and a description of the modern detectors used to do the measurement is given. Techniques on particle reconstruction as well as the Higgs production mechanisms and its decay modes are presented.
* This talk was originally given at a 926 class as a part of the course work
