John Ellis, theoretical physicists: Are we close to discovering the Higgs Boson?
John Ellis, theoretical physicists, answers the question "Are we close to discovering the Higgs Boson and why is it so difficult to find it?" in preparation of the Press Conference following the scientific seminar announcing results of the searches for the Higgs boson on July 4 2012.

ATLAS Event – How ATLAS Detects Particles
This is a segment of the movie 'Episode II, The Particles Strike Back', illustrating how the ATLAS detector detects different types of particles.
ATLAS Event – Protons Accelerate in LHC and Collide in ATLAS
A simulated collision event viewed along the beampipe. The event is one in which a microscopic-blackhole was produced and decayed immediately. The black area in the center with many particle tracks represents the inner detector (pixel detector, semiconductor tracker, and transition radiation tracker), which has been enormously magnified relative to the rest of the detector (in this view) . The colors of the thin tracks have no significance. The thick yellow lines are the two electrons in this event. The green area is the electromagnetic calorimeter, while the red area is the hadronic calorimeter. The green and red histograms show the energy deposits by particles in the electromagnetic and hadronic calorimeters. A muon was added by hand to the event to show how it would look in the detector; it is a thick blue line in the inner detector and orange in the (blue) muon chambers.
