I must confess that I was not aware of this partnership, and I must admit it’s not a partnership I would have seen coming. CERN has teamed up with the organization behind the Eurovision Song Contest, in awarding grants to two multimedia companies to develop content that can spark the scientific curiosity of “tweens”.

Okay, let’s back up a second and define a few terms in this equation. Tweens are described by CERN as children aged 8 to 12; not quite teenagers but no longer big babies either. My teacher friends will shoot me down in flames for this cod-pedology but I guess this age group is old enough to be excited by science but not yet old enough to start truly engaging with scientific concepts.

New portrait of Peter Higgs unveiled

Portrait of Peter Higgs

By Tushna Commissariat

The Royal Society of Edinburgh (RSE) has just unveiled a portrait of famed physicist Peter Higgs, at the Society’s Fellows’ Summer Reception last week. The painting, which will hang on the walls of the Kelvin Room within the RSE’s premises in Edinburgh, was commissioned to one of Scotland’s leading artists, Victoria Crowe, “to honour the man whose outstanding research was instrumental in [the Higgs boson’s] discovery”. The professor seems distinctly unperturbed by the high-energy proton–proton collision taking place in the top right corner of the painting. I shall leave you to find and discern the other interesting imagery in the painting for yourselves – click on the thumbnail to view a larger picture of the portrait.

The worlds of art and science came together yesterday in central London in a celebration of creativity across disciplines. A symposium at Central Saint Martins College of Art and Design was held to recognize the first group of students to complete the Art and Science MA course – the first course of its kind in the UK. Students taking this course are given the chance to explore the “creative relationships between art and science and how to communicate them”.

My colleague, Hamish Johnston, has just returned from a trip to CERN, where he was granted access to the insides of the Large Hadron Colider (LHC), which is currently being upgraded. He has shared some great photos from his trip on the Physics World Facebook page, including some snaps of the interior of the detector experiments.

CMS in all its glory

Admiring CMS

Admiring CMS.

By Hamish Johnston at CERN

Today I had the immense good fortune of seeing the insides of the CMS detector at CERN.

The huge detector was pulled open and I could see all the various layers that are used to track the vast numbers of particles that are produced when protons collide at the Large Hadron Collider.

Unlike earlier photos of the detector that were taken when it was being built, the beamline is still intact as it passes through the CMS – a plain black conduit suspended many metres above the floor. You can see the beamline poking out from the centre of the detector in the photo on the right.

Imperial College’s Jim Virdee was our tour guide, and he told us how several military technologies from the former Soviet Union have been put to good use in the detector. These include brass shell casings that were melted down to make components for the detector.

The physicist and best-selling author Frank Close has joined forces with Michael Marten – founder of the Science Photo Library (SPL) – and CERN Courier editor Christine Sutton to create a new app about particle physics. Called The Particles, the app is billed as an introduction to the Standard Model and is aimed at a wide audience that includes professional physicists, students and even amateur enthusiasts.

Spot-on the Standard Model

By Hamish Johnston

“Beyond any reasonable doubt, it is a Higgs boson, and here we examine the extent to which its couplings resemble those of the single Higgs boson of the Standard Model.”

That’s taken from the abstract of a new paper by John Ellis and Tevong You of King’s College London. Ellis, of course, has been associated with CERN for decades and if he says it’s a Higgs that’s good enough for me!

Much ado about the LHC

By Tushna Commissariat

The Large Hadron Collider (LHC) at CERN has had its share of good and bad press over the past few years. Controversy and rumours abounded when the machine was switched on in September 2008. The mood then turned quickly to disappointment when its magnets failed and finally to euphoria when the first beams collided at 7 TeV in March 2010.

This week, a meeting to discuss the LHC and all things related was held at the Royal Society in London. The “Physics at the High Energy Frontier – the Large Hadron Collider Project” meeting took place on 16–17 May and saw leading lights of the project come together to discuss the collider and its future.

I was at the meeting for the second day, when a press briefing was held where CERN director Rolf-Dieter Heuer, plus Fabiola Gianotti and Guido Tonelli of the ATLAS and CMS experiments respectively, answered all of the questions that the Higgs-hungry reporters could throw at them!

The three speakers described how the collider has “surpassed all expectations” – experimental and computational. Talking about how the LHC is the very essence of global co-operation, Tonelli stressed that “no country could have done it as a stand-alone”. Heuer boasted that every year about 1000 students get their PhDs thanks to the LHC, while just the ATLAS experiment involves about 3000 researchers.

Explaining how things work at the LHC, Tonelli said, “We [experimental scientists] try to test the theory without prejudice. We ask our friends the theorists to come up with something that we can observe.” The collider has already produced the top quark in Europe for the first time and now it is poised to begin a regime of “new physics”, to look for supersymmetry (SUSY), multiple dimensions, matter–antimatter disparity and, of course, the Higgs boson.

The Higgs…or something else?

“We will have an answer to the Shakespeare question for the Higgs – ‘To be or not to be’ – by the end of 2012” declared a confident Heuer. While he did show a great deal of enthusiasm about discovering the Higgs, Heuer was also keen to point out that not finding the particle would be a great result in itself. “Not finding [the Higgs] when it does not exist is a success,” he exclaimed. “If it does not exist, we need to find something else that takes up the job of the Higgs and gives mass to elementary particles,” he added.

The LHC will run until the end of 2012 without any major breaks and Heuer is confident that it will decide the fate of the Higgs by the end of this run. “Physics will not be the same after 2012.” declared Tonelli. “It will change the view of the world.”

Not amused

One of the first questions, asked by BBC reporter Pallab Ghosh, was about the recent ”leak” of an unconfirmed sighting of the Higgs by ATLAS. A sighting that was later denied by a paper released by the ATLAS team and in interviews with physicists on various media channels.

“Unfortunately we live in a world of WikiLeaks, so it leaked!” said a grinning Gianotti. On a more serious note, she explained that such leaked results have not undergone the scientific scrutiny that is necessary, and hence are almost always insubstantial.

“The CERN management was not amused by the leak” said Heuer. He went on to ask journalists not to believe leaked results in the future. “Don’t trust it on first sight” he said. Although Heuer’s displeasure was clear, the leak did put the LHC back in the public eye after a few quiet months. Also, the media interest did provide the public with a rare insight into the vetting process that all scientific discoveries undergo. So perhaps the CERN management should lighten up and enjoy the renewed interest in the LHC!

Bumps and jumps

When asked about the Higgs-like ‘bumps’ seen at other experiments like the Tevatron and CERN’s Large Electron Positron Collider (LEP) the panel had mixed replies. The Tevatron bump was dismissed by Gianotti and Tonelli, as they both explained that it was too small, statistically speaking, and was only seen by one of the Tevatron’s two detectors. Would the LHC have a look for the Tevatron signal? “No”, was their reply.

However, “interesting events” seen at 115 GeV by the LEP just before its closure in 2000 are of interest to them. While Heuer did say that it is very difficult to determine if it was anything more than a “hint”, the LHC will be looking for the Higgs at that energy soon.

Colliding linearly

The International Liner Collider – a possible successor to the LHC – is another project that Heuer is excited about. He feels that CERN, with the LEP and now the LHC under its belt, would be the perfect host for the collider. “I think CERN has huge potential, not only on the human side, but on its experience side. We have all the instruments. So I see CERN in a very good position.” he said.

But what about the money? “If you have an excellent science case, you will get the money. Don’t ask for the money until you have the science figured out.” he said. He pointed out that, compared to the US, in Europe the politics of funding are more stable and for that reason CERN would be a better host.
