CERN Rap

Wednesday, August 6th, 2008

CERN hasn’t really extended its public relations outreach to include rap videos, but a science writer at CERN, Kate McAlpine, has brought particle physics to the hip-hop masses.  The computer voice sounds like, but is not actually, Stephen Hawking.

The latest installment of the West Coast LHC Meetings was held in Davis last week. The meetings are trying to prepare theorists (particularly those living on or near the West Coast) for the flood of data that will arrive from the Large Hadron Collider (LHC) which will run a test beam in 2007 and start full scale running in 2008. The main focus of the meeting was “jets”. when high energy quarks or gluons are produced in particle collisions they appear in the detector as a large spay of particles (called a jet).  Trying to relate the proerties of jets to the properties of the quarks and gluons is a big problem.  Most of the talks are available online.

LHC Olympics

The Large Hadron Collider (LHC) is planned to start running in 2007.  In order to help theorists to prepare themselves, the LHC Olympics are  currently underway. This is a “competition” to analyze simulated data from different models of new physics.  The simulated collisions have been put through a Pretty Good Simulator (PGS) to simulate the results from a LHC detector such as ATLAS or CMS. (By the way, PGS was written by John Conway of UC Davis.)  The idea is to get particle theorists thinking about what real data from the LHC will look like.
