Future Colliders: A strategic perspective

| 20 February 2014 Over the past decades, colliders have defined the energy frontier in particle physics. Currently there are four studies worldwide: ILC, CLIC, FCC and a muon collider. Each high-energy physicist can argue about which one of these should be pursued and have his/her own preference. However, considering the strategic aspect and the time scale involved in realising these machines, the ILC is the natural next energy frontier machine. Harry Weerts, Americas Regional Director for the Linear Collider Collaboration, explains why. Category: Director's Corner | Tagged: , , , , , , , ,

Editors’ note (special banner)

10 October 2013 After 4 July 2012, 8 October 2013 was another important date in the life of particle physicists when the work of François Englert and Peter Higgs was recognised with the 2013 Physics Nobel Prize. At the same moment, the thousands of LHC particle physicists felt also rewarded for their hard work in finding the Higgs particle. Much more than just another member in the particle zoo, the Higgs boson discovery has opened the door to a whole new range of questions, which the LHC and the linear collider will try to solve. Find out more in this issue about how a linear collider can help in study of the Higgs particle and read again our special "Higgs discovery issue" of 5 July 2012. Category: Uncategorized | Tagged: ,

From CERN: New results indicate that particle discovered at CERN is a Higgs boson

21 March 2013 Geneva, 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. Category: Feature | Tagged: ,

From symmetry magazine: What else could the Higgs be?

8 November 2012 According 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. Category: Feature | Tagged: ,

Higgs search presentations at ICHEP 2012

| 9 August 2012 Last 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. Category: Director's Corner | Tagged: , ,

Scientific justification for the ILC

| 14 June 2012 At 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. Category: Director's Corner | Tagged: , , , , ,

From CERN Bulletin: Much ado about Nothing – exploring the vacuum with the LHC

3 May 2012 Empty 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.

From Fermilab Today: Origins of mass: It’s not what you think

19 January 2012 If 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.

From symmetry breaking: Favored Higgs hiding spot remains after most complete search yet

23 November 2011 Almost 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. Category: Feature | Tagged: ,

Articulating the physics case for the ILC

| 17 November 2011 The 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. Category: Research Director's Report | Tagged: , , , ,
