This month, physicists at CERN, the European Laboratory for Particle Physics, are collecting data 24 hours a day as the laboratory's newly upgraded Large Electron-Positron Collider (LEP) smashes particles together at nearly twice its previous energy. The high energies and clean collisions have raised hopes that this accelerator run will yield the first glimpses of the long-sought "supersymmetric" particles.
