Antimatter comes to Brazil

Great minds – some of the delegates at the 50th anniversary meeting of the Brazil Physics Society.

By Matin Durrani in Natal, Brazil

There can’t be many physics experiments to have been visited by members of not one, but two different rock bands. But then there’s something fundamentally captivating about the work of the ALPHA collaboration at the CERN particle-physics lab near Geneva, which is studying the properties of antimatter.

As Jeffrey Hangst from Aarhus University in Denmark revealed in his plenary talk at the 50th anniversary meeting of the Brazilian Physics Society (SBF) yesterday, the ALPHA collaboration has not only played host to a visit from legendary 1970s rockers David Crosby and Graham Nash, but in July also welcomed members of British alternative “space rock” outfit Muse while they were on a visit to CERN.

A horrific nightmare scenario at CERN, surfer wins SUSY bet, and meet the father of the Super Soaker

The “nightmare scenario” of particle physics has a new meaning thanks to a bizarre video that appears to have been made by some scientists at CERN. The video seems to have been filmed at night at CERN’s main campus in Geneva and depicts an occult ceremony in which a woman is stabbed. While the video appears to be a spoof and there is no indication that anyone was actually harmed in its making, CERN officials are rightly concerned that such violent scenes were filmed on their premises. “CERN does not condone this type of spoof, which can give rise to misunderstandings about the scientific nature of our work,” a spokesperson told Agence France-Presse.

And so to bed for the 750 GeV bump

the combined 2015 nd 2016 ATLAS diphoton data

After months of rumours, speculation and some 500 papers posted to the arXiv in an attempt to explain it, the ATLAS and CMS collaborations have confirmed that the small excess of diphoton events, or “bump”, at 750 GeV detected in their preliminary data is a mere statistical fluctuation that has disappeared in the light of more data. Most folks in the particle-physics community will have been unsurprised if a bit disappointed by today’s announcement at the International Conference on High Energy Physics (ICHEP) 2016, currently taking place in Chicago.

The story began around this time last year, soon after the LHC was rebooted and began its impressive 13 TeV run, when the ATLAS collaboration saw more events than expected around the 750 GeV mass window. This bump immediately caught the interest of physicists the world over, simply because there was a sniff of “new physics” around it, meaning that the Standard Model of particle physics did not predict the existence of a particle at that energy. But also, it was the first interesting data to emerge from the LHC after its momentous discovery of the Higgs boson in 2012 and if it had held, would have been one of the most exciting discoveries in modern particle physics.

Dinner that’s out of this world, Higgs pizza and a cosmic symphony

 

By Michael Banks and Tushna Commissariat

Before setting off to the International Space station (ISS) for six months, UK astronaut Tim Peake revealed that one of the meals he would miss most is the classic British roast dinner. So what better way to celebrate the 44 year old’s safe return to Earth last month than to create a portrait of him made from his favourite nosh? Designed by UK “food artist” Prudence Staite for the Hungry Horse pub chain, the culinary creation took 20 hours to make – you can watch a timelapse video of it being created above. The finished portrait weighed in at 12 kg and says “Welcome Home Tim”. Hungry Horse has even offered Tim and his family free roast dinners for life.

Is the 750 GeV bump in LHC data going away?

End of the line: will science journalists be flocking to CERN in August? (Courtesy: CC-BY/Darkzink)

By Hamish Johnston

Things are heating up in the blogosphere after two A-list physics bloggers have speculated that a tantalizing hint of new physics seen by the CMS and ATLAS experiments at CERN is vanishing now that the latest collision data are being analysed.

The hint is a bump at 750 GeV in the spectrum of photon pairs created when protons collide in the LHC. It is not predicted by the Standard Model of particle physics and has not yet reached a statistical significance of 5σ – the threshold for a discovery. If it turns out to be real, the bump could become one of the most important discoveries in particle physics made so far this century.

Fractals and infinite curves, sonified data and farewell to Sir Tom Kibble

By Tushna Commissariat

Fractals have always fascinated me and I am sure it’s the same for many of you. What I find most intriguing about them is how the relatively simple base pattern, or “seed”, quickly scales up to form the intricate designs we see in a snowflake or a coastline. In the video above, mathematician and animator Grant Sanderson has created a montage of “space filling curves” – theoretically speaking, such curves can endlessly expand without every crossing its own path to fill an infinite space. Following on from these curves, Sanderson shows you just how a simple seed pattern grows into a fractal and also describes how small changes to a seed property – such as an angle in a V – can alter the final image. The above video follows from a previous one Sanderson created on “Hilbert’s curve, and the usefulness of infinite results in a finite world” so check them both out.

The toll of a year in space, running a marathon on the ISS, skip-diving at CERN and more

By Tushna Commissariat and Michael Banks

“A year here is a really really long time,” says astronaut Scott Kelly in an interview (watch the video above) that he did on board the International Space Station (ISS) just a month before he returned to Earth in March this year. The retired astronaut is talking about the very real effects of spending a long period in space, specifically citing both the physical effects as well as the “psychological stress” involved. “During my time in orbit, I lost bone mass, my muscles atrophied and my blood redistributed itself in my body, which strained my heart. Every day I was exposed to 10 times the radiation of a person on Earth, which will increase my risk of developing a fatal cancer for the rest of my life. Not to mention the psychological stress, which is harder to quantify and is perhaps as damaging,” he says.

The comments were part of the announcement of his upcoming memoir, Endurance: My Year in Space and Our Journey to Mars, which will be published later this year. Despite the damming tone, Kelly is still a staunch supporter of manned spaceflight and missions such as those to Mars, he just has a much clearer view on the realities involved. Read more about his announcement over at the GeekWire website.

Sometimes, the biggest laughs on April Fools’ Day come from the stories that read like hoaxes but are actually true. One such item is a proposal by David Kipping and Alex Teachy of Columbia University in the US, who have come up with a way of hiding the Earth from aggressive civilizations on distant planets (at least I think this is real, but I wouldn’t be surprised if it were an elaborate hoax!).

Carried away by a well lit shadow

By James Dacey

As concept albums go, the latest release by Jake Hertzog can certainly be stacked at the intellectual end of your record collection. This week, the US jazz-rock guitarist released his sixth studio album, entitled Well Lit Shadow – a suite of solo electric-guitar tracks inspired by images from the Large Hadron Collider (LHC) and other experiments at the CERN particle-physics lab. You can find details of how to purchase or stream the album on Hertzog’s website.

Now, I’m not the world’s biggest jazz aficionado but I gave the album a listen and it’s far more accessible than the concept might suggest. Hertzog’s musicianship shines through and bright walking riffs on tracks such as “Star Drops” and “Traces of You” evoke images of devoted researchers working through vast amounts of data in pursuit of knowledge. According to Hertzog’s website, some of the pieces are very literal attempts to depict the chaos and beauty of subatomic-particle collisions, while other tracks are more abstract meditations on the deeper meaning of these experiments. The album’s title track is described as “a musical poem dedicated to the philosophical implications of this science”.

CMS on canvas

We’ve already had a LEGO model of the giant CMS detector at CERN’s Large Hadron Collider (LHC) but now University of Leicester modern literature student Genevieve Lovegrove has attempted to go one better by creating a collage of the LHC detector made from everyday objects.
