A Better Mass for the W Boson; Higgs Boson Given Less Space to Hide

Image of the collision of a proton and antiproton.

Snapshot of a collision. This image from the DZero detector shows a typical outcome of the collision of a proton and an antiproton at Fermilab's Tevatron. 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.

NSF's Lisa-Joy Zgorski interviews two high energy physicists at Fermi National Accelerator Laboratory: Darien Wood, co-spokesperson for DZero, and Jacobo Konigsberg, co-spokesperson for CDF. Both programs collect and analyze data via detectors along sites on the Tevatron. Both describe their search for the so-called God particle or Higgs boson, as well as other products resulting from high energy collision physics.
