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.
