Colliding Particles: Webisodes Starring Large Hadron Collider Physicists

Colliding Particles Part 4 is the latest in a series of short web videos featuring physicists involved in research at the new Large Hadron Collider (LHC) at CERN in Switzerland.

Episode 4, 'Problems' travels to Paris for a look at some of the theoretical work behind the 'Eurostar' paper. Gavin and his PhD student Mathieu explore the mathematics behind the behaviour of fundamental particles, and we have an update on the 'incident' which is holding up work at the LHC. For an introduction to the 'Eurostar' project, watch Episode 1.
