The Nobel Prize in Physics 2004

  desy   The theory shows its true colours

The aftermath of a high-energy collision between a proton and an electron, as seen by the H1 experiment at the DESY laboratory in Hamburg. The experiment is shown in cross-section, perpendicular to colliding beams of protons and electrons. The electron has struck one of the quarks in a proton. An impressive shower of particles – providing information about the struck quark – is spontaneously produced from the energy strored in the gluon force-field. The charged particles in the shower bend in the experiment’s strong magnetic field.
