Electron’s negativity cut in half by supercomputer

While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart.

CERN plans to announce latest results in search for Higgs boson particle

(PhysOrg.com) -- Physicists collaborating on experiments at the Large Hadron Collider (LHC) at CERN – the European Organization for Nuclear Research in Geneva – will announce their latest results in the search for the Higgs boson particle on Tuesday 13 December.

Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement

The physics buzz reached a frenzy in the past few days over the announcement that the Large Hadron Collider in Geneva is planning to release what is widely expected to be tantalizing--although not conclusive--evidence for the existence of the Higgs boson, the elementary particle hypothesized to be the origin of the mass of all matter.

Timing particle flight

A time-of-flight detector designed by a research team led by UT Arlington Physics Professor Andrew Brandt could one day significantly boost measurement capabilities at the Large Hadron Collider, or LHC, in Geneva, Switzerland.

The Tevatron: Three Decades of Discovery

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.

Rare particle decay could mean new physics

(PhysOrg.com) -- An incredibly rare sub-atomic particle decay might not be quite as rare as previously predicted, say Cornell researchers. This discovery, culled from a vast data set at the Collider Detector at Fermilab (CDF), is a clue for physicists trying to catch glimpses of how the universe began.

LHC experiments eliminate more Higgs hiding spots (Update)

(PhysOrg.com) -- Two experimental collaborations at the Large Hadron Collider, located at CERN laboratory near Geneva, Switzerland, announced today that they have significantly narrowed the mass region in which the Higgs boson could be hiding.

A hint of Higgs: An update from the LHC

The physics world was abuzz with some tantalizing news a couple of weeks ago. At a meeting of the European Physical Society in Grenoble, France, physicists -- including some from Caltech -- announced that the latest data from the Large Hadron Collider (LHC) might hint at the existence of the ever-elusive Higgs boson.

Will the real Higgs Boson please stand up?

Although physicists from two experiments at CERN's Large Hadron Collider and from Fermilab’s Tevatron collider recently reported at the Europhysics Conference on High Energy Physics that they didn't find the Higgs boson, they're continuing to home in on the elusive particle, prompting Rolf-Dieter Heuer, the Director General of CERN, to go on record that he believes a neutral Higgs boson will be found by the LHC by the end of 2012.

Physicists excited by hints of Higgs boson existence

Birmingham particle physicists are today trawling through the data from particle collisions at the Large Hadron Collider that could indicate the existence of the Higgs boson.

Large Hadron Collider Sees Tantalizing Hint of Higgs Particle

By Geoff Brumfiel of Nature magazine For now, physicists are only willing to call them "excess events," but fresh data from two experiments at the Large Hadron Collider (LHC) are hinting at something unusual--and it could be the most sought-after particle in all of physics. Both ATLAS and the Compact Muon Solenoid (CMS) experiments are seeing an unusual surplus of events in a rough mass range of 130-150 gigaelectronvolts (energy and mass are used interchangeably in particle physics).
