By Eugenie Samuel Reich of Nature magazine A hint of the Higgs boson , the missing piece in the standard model of particle physics, has been found in data collected by the Tevatron, the now-shuttered U.S.

(PhysOrg.com) -- New measurements announced today by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory indicate that the elusive Higgs boson may nearly be cornered.

(PhysOrg.com) -- University of Chicago physicists Henry Frisch and Melvyn Shochet became involved with the Tevatron particle accelerator when it was still in the planning stages at Fermi National Accelerator Laboratory in 1976.

Most everything you need to know about a particle collider can be summed up with just two numbers. The first is its energy--higher energies let scientists conjure up more massive particles (measured in gigaelectron volts, or GeV). The second is its luminosity, or the number of collisions per second.

The era of big American physics ends Friday with the retirement of the Tevatron particle accelerator, which has been recreating the Big Bang under four miles of Illinois prairie for 25 years.

By Eugenie Samuel Reich of Nature magazine Research groups at the Tevatron, the proton-antiproton collider at Fermilab in Batavia, Illinois, have reached starkly different conclusions about a possible sighting of new particles beyond what is expected under the standard model of particle physics. In April, researchers on the Collider Detector at Fermilab (CDF) experiment reported tentative evidence that particles not predicted by the standard model had surfaced in collisions that produced a W boson--a particle of the weak nuclear force--and jets of other particles.

Sound analysis of sperm whale “clicks” suggests they might have names, similar to the individual, identifying whistles that dolphins display. And we thought they just sang to one another.

(PhysOrg.com) -- Around midnight this night CERN's Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 x 1032cm-2s-1. This exceeds the previous world record of 4.024 x 1032cm-2s-1, which was set by the US Fermi National Accelerator Laboratory's Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

Physicists sifting through data generated by the Tevatron particle collider in Illinois have uncovered a signal that neither they nor the long-standing Standard Model of particle physics can explain. [More]
