Canadian leads publishing of first results from Large Hadron Collider

13.10.2010
Ground-breaking experiments in Switzerland question Universe's building blocks

Researchers used Einstein's famous E=mc2 equation and the Large Hadron Collider to recreate a miniature version of the event at the origins of our Universe, and the first findings from their work were published in the journal Physical Review Letters. Dr. Andreas Warburton of McGill's Department of Physics made leading contributions to the analysis of data from the experiment, known as "ATLAS," meaning the findings have a special significance for Canadian science.

Warburton and 3171 colleagues from around the world are using the data collected from the recreation in an attempt to look for exotic new particles whose existence is suggested by theoretical calculations. His work may help to revolutionize our understanding of the fundamental components of the Universe.

"Understanding whether new kinds of matter exist or not is interesting because it holds clues to knowledge about how the Universe works fundamentally," Warburton said. "The Standard Model of Particle Physics is a useful theoretical framework but it is known to be flawed and incomplete – we are searching for new particles that lie outside this framework, and we are also seeking to establish the non-existence of these hypothetical particles." The research published this week falls into the latter category and is about determining the mass of a theoretical particle known as an "excited quark."

Warburton offered the following analogy: "By exploring the high-energy subatomic frontier, it is metaphorically somewhat like turning over stones at the seashore and looking for new and interesting surprises hiding under the rocks. Here we are looking under stones that have been too heavy to lift before this summer. What we see or don't see under those stones helps to paint new pictures about how the Universe works and tells us which stones are most important to look under next."

"The results reported in our paper have been awaited for a long time and by many people," Warburton said. "There was friendly competition amongst us as to who will be the first to make a publishable measurement that either excludes or discovers New Physics, and I am proud that the ATLAS team won this race. I feel fortunate and privileged to have played a leading role in getting the analysis into a publishable form in a very short time." Warburton has since returned from Geneva to Montreal and his office at McGill University.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
