The first image shows a pair of top quarks reconstructed in the Collider Detector at Fermilab (CDF). Each top quark decays to a W boson and a b quark. The pink tower in the wide view identifies a positron (an anti-electron) from one W decay; the inset shows displaced decays of two b particles (red tracks). The second image shows a pair of top quarks reconstructed in the DZero experiment at Fermilab. This end view shows the final decay products: two muons (turquoise), a neutrino (pink), and four jets of particles. The height of the boxes denotes the amount of energy deposited in the detector in each wedge.
