Fighting the scourge of mental illness means giving psychiatry the kind of boost that physics got from the Higgs hunt by Nick Craddock (….) Recently, some colleagues and I launched a report, Strengthening Academic Psychiatry in the UK, and found ourselves justifying how psychiatry had acquired – and was still struggling to shrug off – […]

what is it, and why do we badly need it? Wolfgang Bietenholz We sketch in simple terms the concept of the Higgs mechanism, and its importance in particle physics. To the best of our knowledge, the world consists of only very few types of elementary particles, the smallest entities of matter, which are indivisible. They […]

by Michael Slezak HOPES of using the Higgs boson and the elegant theory of supersymmetry as shortcuts to discovering the mysteries of the universe are evaporating fast. That’s the verdict of a major update from the Large Hadron Collider in CERN, near Geneva, Switzerland – the first since a boson resembling the Higgs was spotted […]

By Daisy Yuhas If you’ve read anything about the Higgs boson, you probably know that this particle is special because it can explain how fundamental particles acquire mass. Specifically, evidence of the boson is evidence that an omnipresent Higgs field exists—one that slows particles down and makes them heavy. But there’s a misconception that sometimes […]

Jeff Forshaw The dust is beginning to settle – a new particle has been discovered using the Large Hadron Collider. Discovering new particles of nature is not an everyday occurrence and we are reasonably entitled to proclaim that this is the arrival of the Higgs. We aren’t certain, though: more careful examination of the particle’s […]

By Tommaso Dorigo ATLAS has just released a note which summarizes the searches for the standard model Higgs boson in 7-TeV and 8-TeV data. Since July 4th the main improvement is the addition of the WW channel, which had not been shown back then. With it, the combined local significance of the 126 GeV Higgs […]

Scientists at the Large Hadron Collider (LHC) announced the discovery of a Higgs-like boson on July 4 – but what does that mean? What’s a Higgs boson? And how can a particle be like a Higgs? Read on to learn more about the new particle and how it fits into our world. The following questions were asked […]

Einstein famously marveled over the idea that the universe was comprehensible. But on July 4, the universe started to sound weird and unnecessarily complicated. Physicists worldwide were celebrating an elusive thing called the Higgs Boson, which had apparently made a brief appearance. They kept repeating that it was important because it gives matter mass, but […]

The lecture has been conceived for students not yet familiar with advanced physics and is suitable for several disciplines, other than physics. The Higgs mechanism is […]

The elusive Higgs boson, or something very close, has finally been spotted at CERN’s Large Hadron Collider near Geneva, Switzerland. The next challenge is to pin down whether the new particle is the boson physicists were expecting or some other beast. One of the first things physicists want to know about the new particle is itsspin, a […]

At least two other particles could be masquerading as the God particle, according to a new analysis of the data from CERN The news coming out of CERN in recent weeks has been hard to miss. At first, there was a dripfeed of gossip which turned into a firehose of ‘Higgsteria’. Finally, last Wednesday, CERN […]

The announcement early yesterday morning of experimental evidence for what’s presumably the Higgs particle brings a certain closure to a story I’ve watched (and sometimes been a part of) for nearly 40 years.

by Jacob Aron It’s turned into science’s worst-kept secret. Tomorrow, physicists at CERN near Geneva in Switzerland are expected to announce the discovery of the Higgs boson, the culmination of a 50-year quest to find the elusive particle that gives others their mass. Here’s how they got there. 1964 Peter Higgs is the first to […]

Frank Wilczek Newtonian mechanics posited mass as a primary quality of matter, incapable of further elucidation. We now see Newtonian mass as an emergent property. Most of the mass of standard matter, by far, arises dynamically, from back-reaction of the color gluon fields of quantum chromodynamics (QCD). The equations for massless particles support extra symmetries […]

Scientists at the Large Hadron Collider (LHC) will increase the energies of the bunches of subatomic particles called protons that it smashes together. The boost should improve the collider’s chances of discovering “new physics” and definitively confirming or denying the existence of Higgs boson particle. The proton beams’ energies will be increased by 14%, for […]

In December 2011, the elusive Higgs boson was back in the limelight when hints of the particle emerged in the wreckage of proton collisions at the world’s most powerful particle smasher – the Large Hadron Collider (LHC) near Geneva, Switzerland. There have been no new collisions since, but researchers from the LHC’s two main detectors […]

John Ellis, Mary K. Gaillard, Dimitri V. Nanopoulos The Higgs boson was postulated in 1964, and phenomenological studies of its possible production and decays started in the early 1970s, followed by studies of its possible production in e+ e-, pbar p and pp collisions, in particular. Until recently, the most sensitive searches for the Higgs […]

RECENT hints of a featherweight Higgs boson don’t just take us nearer to a complete standard model of physics. The results affect a possible link between the Higgs and dark matter, the invisible stuff making up 80 per cent of the universe’s matter. The Higgs is the last remaining hole in the standard model, the […]

The main conclusion is that the Standard Model Higgs boson, if it exists, is most likely to have a mass constrained to the range 115.5-131 GeV by the ATLAS experiment, and 115-127 GeV by CMS 13 December 2011. In a seminar held at CERN today, the ATLAS and CMS experiments presented the status of their […]

Higgs boson hunters often catch themselves dreaming of the boson having a mass high enough to give rise to the spectacular decay into two Z bosons, and then four charged leptons in the final state.
