Large Hadron Collider used to recreate miniature version of beginning of Universe

Summary:
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 have just been published.

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.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
