Physicists working with a Fermilab neutrino experiment may have found a new elementary particle whose behavior breaks the known laws of physics. If correct, their results poke holes in the accepted Standard Model of particles and forces, and raise some interesting questions for the Large Hadron Collider and Tevatron experiments. The new particle could even explain the existence of dark matter.
As particle physicists gather this week for a conference in Paris, they’re reporting progress toward finding the elusive Higgs boson, with two groups suggesting a Higgs discovery may not be far off.
Physicists from Fermilab in Illinois announced they combined the results of two experiments to refine their search for the Higgs, sometimes called the “God particle” because it is thought to endow particles with mass.
The New York Times reports on some unlikely results of experiments at the Tevatron, the particle accelerator at the Fermi National Accelerator Laboratory in Batavia, Ill. The new findings could shed light on why the universe has a preponderance of matter over antimatter, and therefore something rather than nothing.
This is actually a nutria—not to be confused with a neutrino, which would have far less mass
Scientists at the Fermi National Accelerator Laboratory in Batavia, Illinois, announced yesterday the first results of the MINOS experiment, which corroborate an experimental result from 1998 that suggested that a class of subatomic particles called neutrinos have mass. This deviates from the Standard Model of particle physics—which predicts the number and behavior of subatomic particles and depends on a massless neutrino—and indicates that the model needs to be revised, or replaced with a more accurate one. Now, if we could only find the Higgs boson. —Martha Harbison
