In anticipation of the potential for experimental verification of the existence of the Higgs boson?a long-hypothesized particle thought responsible for endowing other elementary particles with mass?the World Leaders Forum hosted a special program, co-sponsored by the Columbia Science Initiative, on April 18 at 4:00 p.m. in the Low Library rotunda. more; http://news.columbia.edu/higgs http://youtu.be/pt8oRWNSwAk http://youtu.be/C0rBKyU1vu0

The plot is thickening for the still-hidden Higgs boson. Two US-based experiments report new, hopeful hints of the slippery particle, but one of the two main detectors at the Large Hadron Collider (LHC) says an existing signal has started to fade away. The announcements, all made today at the Recontres de Moriondmeeting in La Thuile, Italy,… [Read more…]

by Lisa Grossman The Tevatron may now be defunct, but it is still detangling the nature of matter from beyond the grave. The late particle-smasher’s two main experiments, CDF and DZero, have released the most precise measurement yet of the mass of the W boson, one of the fundamental particles in the standard model of… [Read more…]

… points to Higgs mass and tests Standard Model The world’s most precise measurement of the mass of the W boson, one of nature’s elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory. The new measurement is an important, independent constraint of… [Read more…]

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… [Read more…]

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… [Read more…]

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… [Read more…]

W.-D. Schlatter (CERN), P. M. Zerwas (DESY) After a brief introduction to the theoretical basis of the Higgs mechanism for generating the masses of elementary particles, the experimental searches for Higgs particles will be summarized, from bounds at LEP to inferences for LHC. The report will focus on the Standard Model, though some central results… [Read more…]

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… [Read more…]

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… [Read more…]

Tantalising hints of the Higgs boson will be confirmed or ruled out at the LHC in the coming months, say researchers by Ιan Sample Physicists at the Large Hadron Collider near Geneva are edging ever closer to answering one of the most profound questions in particle physics: does the Higgs boson exist? Speaking at a… [Read more…]

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. At a hadron collider -let’s talk of the LHC to be specific- such a signature is the only one providing… [Read more…]

For almost 20 years, Bill Murray has been hunting the Higgs boson, the elusive subatomic particle that is thought to give mass to the basic building blocks of nature. In those two decades, the 45-year-old Edinburgh-born researcher has watched the search for the holy grail of physics narrow to a tighter and tighter group of… [Read more…]

ROGER DIXON gestures, bringing his hand alarmingly close to the big red button that has the power to shut down one of the world’s most powerful particle accelerators forever. “It’s already hooked up,” he says, in response to my nervous questions.

The Universe wouldn’t be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle. The race to identify the Higgs boson is on at CERN. This Holy Grail of particle physics would help explain why the majority of elementary particles possess… [Read more…]

Signals reported in July seemed to indicate that the Higgs boson – a long-theorised particle seen as a missing link in our current understanding of physics – might have been detected among data the Large Hadron Collider at CERN in Geneva. But since then, those signals – hinting that the theoretical ‘God’ particle might have… [Read more…]

The Large Hadron Collider fired mankind into a “new era of science” in March last year producing the world’s first highenergy particle collision. After years of setbacks, the £4.4billion machine has been smashing together protons using three times the speed and energy of previous experiments. The collider, which is housed at the European Centre for… [Read more…]

U.S.-based physicists said on Monday they hope to have enough data by the end of this month to establish if the elusive Higgs boson, a particle thought to have made the universe possible, exists in its long-predicted form. If the answer is no, scientists around the globe will have to rethink the 40-year-old Standard Model… [Read more…]

Cern scientist says he sees ‘no striking evidence of anything that could resemble a discovery’ in hunt for Higgs boson Ripples of excitement swept through the physics community last month when Cern scientists reported what looked like glimpses of the long-sought Higgs boson. But the hopes have been dashed as it was revealed that the tantalising hints had all but… [Read more…]

The W boson carries the weak nuclear force. At the Large Hadron Collider pairs of them may be showing the first signs of the Higgs boson. But they are a decidedly mixed blessing. The current data from the LHC show an effect which might, or might not, be the first indication of the presence of… [Read more…]

Unlike, for example, most things Ben Goldacre writes about, lives don’t hang in the balance. But many of the same issues apply – statistical confidence, systematic bias, blinding of experiments and so on. Real knowledge about the fundamental nature of the universe will emerge from rumour, claim, counter-claim and honest doubt I wrote before the EPS meeting in… [Read more…]

A US particle machine has seen possible hints of the Higgs boson, it has emerged, after reports this week of similar glimpses at Europe’s Large Hadron Collider (LHC) laboratory.

P. Cea, L. Cosmai We further elaborate on the triviality and spontaneous symmetry breaking scenario where the Higgs boson without self-interaction coexists with spontaneous symmetry breaking. The trivial Higgs boson is rather heavy with mass m_H = 754 +/- 20 (stat) +/- 20 (syst) GeV and total width \Gamma(H) \simeq 320 GeV. We briefly discuss… [Read more…]

NEW particles that mimic the long-sought Higgs boson may bamboozle physicists, who could spend years trying to confirm or rule out the possibility of an impostor, a new study warns. The standard model of particle physics predicts that a particle called the Higgs boson endows many other particles with mass. The Large Hadron Collider (LHC) at CERN… [Read more…]

Now you see it, now you don’t. Rather like a conjurer’s white rabbit, the elusive Higgs boson may have slipped from sight again.
