ILC NewsLine special issue: the higgs


The news was impossible to miss: LHC experiments ATLAS and CMS found a new particle in their data that could be the Higgs boson. Auditoriums were packed, excitement was high. The theorists who predicted the boson's existence received standing ovations. There was #Higgsteria on twitter – 4 July 2012 was Higgs day. Read CERN's press release or view the pictures and videos to relive the moment. But what does all this mean for the ILC? It's definitely good news. Find out how the ILC can help in the search and study in this special Higgs issue of ILC NewsLine.


The Higgs is Different

Theoretical physicist and ILCSC chair Jonathan Bagger explains how

by Jonathan Bagger

The Higgs is Different, says Jonathan Bagger, a theoretical physicist and chair of the International Linear Collider Steering Committee ILCSC. It has no spin, it fills the vacuum, but most importantly, it opens the door to a new range of questions. Questions which a linear collider with its clean and controlled collisions could help answer.

Research Director's Report

Encouraging news from CERN

by Sakue Yamada

We in the ILC Research Directorate are thrilled with the announcement from CERN this week that a Higgs-like particle has been discovered. The Higgs particle has been a target of our experiments for over decades, and the affirming news from LHC finally means a great step forward. I wish to congratulate CERN and all physicists who contributed to this success.

Director's Corner

The Higgs and the ILC

by Barry Barish

The announcements of the most recent results from the search for the Higgs boson at the LHC bring into sharper focus the new physics at the energy frontier and the potential role of the ILC. Although it is still too soon to know what will be uncovered regarding the Higgs mechanism from studies at the LHC, it is worth pointing out the long-range potential for Higgs physics at the ILC. Two examples illustrate how the ILC will be able to shed further light on the phenomena seen at the LHC.


Make no assumptions

A linear collider would complete the picture

by Barbara Warmbein

The LHC experiments are definitely homing in on a Higgs boson in a mass region somewhere around 126 GeV. Further studies and more data from the LHC will tell us more about what it is that they have found, but only a linear collider will be able to tell without prejudice whether it’s a Standard Model Higgs (or not) and determine its mass with a precision down to about 60 MeV. Here’s how.

After all of this week's news, press releases, blog posts, backgrounders and newspaper stories here's more about the Higgs - catchy, rhythmic and full of clever lyrics. If you think you've still not grasped the Higgs mechanism this song will stick in your head! It's "The Particle Physicists' Song" (based on "The Hippopotamus Song" by Michael Flanders and Donald Swann), with lyrics by Danuta Orlowska, performed by the CERN choir in the CERN Control Room in 2010. Enjoy and pass the tune on to your colleagues...

Surrounded by cameras and showing a variety of emotions – delighted, touched, excited, shy, proud, almost overwhelmed – the central theorists, CERN management and the spokespeople of the experiments get together for a group picture after yesterday's press conference. Front row, left to right: theorist Francois Englert, theorist Peter Higgs, ATLAS spokeswoman Fabiola Gianotti, CERN director Steve Myers. Back row, left to right: CERN director Sergio Bertolucci, CERN DG Rolf Heuer, CMS spokesman Joe Incandela, theorist Carl Hagen, theorist Gerald Guralnik. Missing in the picture: Robert Brout and Tom Kibble and the rest of the ATLAS and CMS collaborations.

    В настоящее время существуют два крупных пост-БАКовских проекта. Это Международный электрон-позитронный линейный коллайдер (ILC, International Linear Collider), в создании которого уже сейчас участвуют почти 300 лабораторий и университетов по всему миру. ILC должен будет детально исследовать свойства бозона Хиггса, если последний будет открыт с помощью БАКа. (google translation)

    Gross said a linear collider of electrons and positrons would make it easier to test the properties of the particle, “but that is not likely for 10 to 20 years. Maybe this result gives motivation for building one.” Regardless, “experimentalists, as they have proved today, are extremely clever,” teasing out small signals with the instruments they have.
