The hunt for the Higgs boson, that most elusive particle of physics, the one that gives things mass, came closer to an end on July 4. Experiments at Europe's Large Hadron Collider, the world's largest particle accelerator, revealed evidence of the particle and its energy field. But the LHC didn't do it alone. The search has been a massive, costly and unprecedented international effort that began thousands of miles away, at another atom smasher beneath the Illinois prairie.
“We have discovered a new particle,” CERN director general Rolf Heuer said Wednesday morning. “A boson. Most probably a Higgs boson.” Even the most anticipated news in science does not come without some caveats.
Still, all signs point to a discovery today, arguably one of the most important findings in modern physics. The inscrutable Higgs boson, carrier of mass and final puzzle piece of physics’ prevailing theory, may have finally been found. Now comes the fun part — depending on what it looks like, this saga may be just beginning. [UPDATED]
If the Tevatron was a metal detector sweeping across a proverbial beach, the beeps of discovery would have been coming in very close succession at the end of its life. It was, we have learned, extremely close to finding the treasured Higgs boson ... and then, last September, it shut down. Only another, more powerful detector, owned by someone else, will finally be able to grab it.
Before it stopped colliding for good, America’s defunct Tevatron collider saw a hint of the elusive Higgs boson, physicists announced Wednesday. Even more interesting: Scientists spotted something unusual in the same energy range where their European colleagues glimpsed something unusual at the Large Hadron Collider last winter.

in the beginning of the beginning, the exploding hot universe was full of elementary particles, but the particles had no mass. The universe also contained force fields, and one of those fields, the Higgs, cooled and condensed into a quantum liquid. The liquid dragged on the other particles, giving them mass. The liquid rippled, and the ripples formed a new particle, called the Higgs.
Though researchers think the Higgs boson is running out of places to hide, the LHC has yet to provide conclusive proof of its existence. But the ATLAS experiment at the LHC--one of the two main experiments taking precise measurements of particle collisions--has found what is thought to be the first observation of a new particle at the world's largest science experiment.
Physicists at CERN may have caught the first whiffs of the elusive Higgs boson, researchers announced this morning, but more numbers must be crunched before anyone will claim its discovery. Bumps in signals at the Large Hadron Collider are not surefire proof of the so-called god particle, at least not yet — but at the very least they're enough to keep faith in our modern theories of physics.
There's no official announcement yet--that comes next week--but word on the street and around the cafeteria at CERN says that scientists may announce that they've glimpsed the elusive Higgs boson at a meeting scheduled for Tuesday.
As we all know, the Large Hadron Collider has been grievously behind the times technologically. Sure, its giant array of superconducting magnets, kept cool by almost a hundred tons of liquid helium is pretty neat, and the muon spectrometer is no slouch. But the LHC hasn't put it all in a convenient smartphone app -- until now.
With LHSee, released today by CERN's app specialists, you can investigate the fundamental nature of the universe -- the nature of spacetime, the origin of matter -- while you wait for the bus.
Fermilab’s Tevatron collider runs out of money and time at the end of this month, but physicists there say that they are on track to establish whether the Higgs can exist within the most likely predicted mass range before their September 30 deadline. That’s not the same as actually finding the Higgs boson of course, but physicists say they’ll either rule out the possibility of its existence or not by month’s end.
