P H Y S I C S C O L L O Q U I U M Richard Cavanaugh University of Florida "The LHC and CMS: Probing the Great Questions of Particle Physics and Cosmology" ABSTRACT The Large Hadron Collider (LHC) is the largest scientific instrument ever built and is expected to circulate and collide proton-proton beams later this year at a center-of-mass energy of seven times higher than any previous collider, probing distances more than 1000 times smaller than size of a proton. In this talk, I will discuss the potential for the Compact Muon Solenoid Detector (CMS), one of four experiments at the LHC, to discover new phenomena beyond the Standard Model of Particle Physics, including the exciting possibility that dark matter might be produced in the laboratory. Finally, I will discuss some of the computing advances which are being pioneered by the high energy physics community to address the new challenges of data intensive science.
