Searching for New States of Matter with the CMS Experiment


The CMS experiment was designed to search for new particles, such as the Higgs Boson, strings or dark matter candidates. However it is also a superb detector to investigate a new state of matter, the Quark Gluon Plasma or QGP, created in heavy ion collisions. I will review some of the basic properties of the plasma and show how CMS gives us new penetrating probes to study it. In particular I would like to focus on the difference between the electro-weak probes and colored objects such as light or heavy quarks lose energy in the plasma and how we might try to measure its temperature. Finally I will speculate how CMS may be the ideal experiment to study another conjectured state of matter, the Colored Glass Condensate, using lead-lead and proton-lead collisions.
