This image from the DZero detector shows the typical outcome of a collision of a proton and an antiproton at Fermilab's Tevatron collider. The curved red paths mark the trajectories of charged particles recorded in the detector's central tracking chamber. The colored bars indicate particle energies deposited in the detector. The blue disks correspond to part of DZero's physical structure. Physicists analyzed several years' worth of results from the Tevatron collider and came up with the most accurate measurement to date of the mass of the W boson, as well as narrowed down the possible mass of the undiscovered (at that time) Higgs boson.
