21 March 2013Geneva, 14 March 2013. At the Moriond Conference today, the ATLAS and CMS collaborations at CERN1’s Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year. Having analysed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles. It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model. Finding the answer to this question will take time.

8 November 2012According to the Standard Model, the mass of the Higgs boson should be enormous. But recent experimental results suggest it’s quite small, indicating that scientists might need to go beyond the Standard Model to explain the new particle.

Barry Barish | 9 August 2012Last month, both LHC experiments at CERN announced the discovery of a new particle with mass of 125.5 GeV, which is likely the long-sought Higgs boson. It made headlines worldwide. This is indeed an exciting moment for particle physicists and it came just prior to our largest scientific meeting, the biannual International Conference on High Energy Physics ICHEP held in Melbourne, Australia. In Melbourne, the detailed and impressive scientific evidence was presented to the worldwide particle physics community.

Barry Barish | 14 June 2012At the KILC12 workshop in Daegu, Korea, in May, there was a panel discussion on the topic of what will be required to provide scientific justification for the International Linear Collider. The panel consisted of a cross-section of workshop attendees, accelerator physicists, detector experts, theorists and even one of our communicators. The panel discussion produced areas of agreement, some differences and homework.

3 May 2012Empty space is anything but. Remove everything you can from an area of space and it will still bustle with activity. A veritable abundance of particles and all-pervasive fields fill space with energy. Empty space even weighs something. Indeed, studying ‘nothing’ can tell us almost everything about the universe we live in. Learn more about the relationship between vacuum and “virtual” particles, the Higgs boson, supersymmetry and dark energy

19 January 2012If you have even the faintest interest in particle physics, you've heard about the Higgs boson. The Higgs boson is the leading candidate explanation for the origin of the masses of point-like subatomic particles. By extension, the Higgs boson is the origin of mass in the universe, right? There's only one problem with that statement—it's totally wrong. Read the full article in Fermilab Today.

23 November 2011Almost a year of work, more than 50 meetings and plenty of diplomacy went into calculating the LHC experiments’ first combination of Higgs search results. The study, made public on 18 November, eliminates several hints the individual experiments saw in previous analyses but leaves in play the favored mass range for the Higgs boson, between 114 and 141 GeV. ATLAS and CMS ruled out at a 95 percent confidence level a Higgs boson with a mass between 141 and 476 GeV.

Michael Peskin | 17 November 2011The ILC Detailed Baseline Design report will contain a chapter that describes the physics opportunities that the ILC will offer. The LHC is bringing us new information about particles in the ILC energy range. But what exactly is the Large Hadron Collider telling us, and what are the implications for the ILC programme? Michael Peskin encourages members of the ILC community to debate this question and contribute to the report.

Rika Takahashi | 10 November 2011Few particles get as much attention today as the theorised Higgs boson, which so far has eluded detection. Whatever the outcome of the Large Hadron Collider's search for it - whether it finds a Higgs particle or not - there is still compelling physics that a future collider should explore.

11 August 2011How can a low-energy experiment like SLAC’s PEP II B Factory, originally built to investigate differences between matter and antimatter and no longer even taking data, compete with a monster matter masher like the LHC that was built, in a large part, to find the Higgs?
