After all the foofaraw about finding/confirming the existence of the Higgs Boson or ‘god’ particle (featured in my July 4, 2012 posting amongst many others), the Royal Swedish Academy of Sciences has decided to award the 2013 Nobel prize for Physics to two of the individuals responsible for much of the current thinking about subatomic particles and mass (from the Oct. 8, 2013 news item on ScienceDaily),
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2013 to François Englert of Université Libre de Bruxelles, Brussels, Belgium, and Peter W. Higgs of the University of Edinburgh, UK, “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”
François Englert and Peter W. Higgs are jointly awarded the Nobel Prize in Physics 2013 for the theory of how particles acquire mass. In 1964, they proposed the theory independently of each other (Englert together with his now deceased colleague Robert Brout). In 2012, their ideas were confirmed by the discovery of a so called Higgs particle at the CERN laboratory outside Geneva in Switzerland.
TRIUMF, sometimes known as Canada’s national laboratory for particle and nuclear physics, has issued an Oct. 8, 2013 news release,
HIGGS, ENGLERT SHARE 2013 NOBEL PRIZE IN PHYSICS
Canadians Key Part of Historical Nobel Prize to “Godfathers” of the “God Particle”
(Vancouver, BC) — The Royal Swedish Academy of Sciences today awarded the Nobel Prize in physics to Professor Peter W. Higgs (Univ. of Edinburgh) and Professor François Englert (Univ. Libre de Bruxelles) to recognize their work developing the theory of what is now known as the Higgs field, which gives elementary particles mass. Canadians have played critical roles in all stages of the breakthrough discovery Higgs boson particle that validates the original theoretical framework. Throngs across Canada are celebrating.
More than 150 Canadian scientists and students at 10 different institutions are presently involved in the global ATLAS experiment at CERN. Canada’s national laboratory for particle and nuclear physics, TRIUMF, has been a focal point for much of the Canadian involvement that has ranged from assisting with the construction of the LHC accelerator to building key elements of the ATLAS detector and hosting one of the ten global Tier-1 Data Centres that stores and processes the physics for the team of thousands.
“The observation of a Higgs Boson at about 125 GeV, or 130 times the mass of the proton, by both the ATLAS and CMS groups is a tremendous achievement,” said Rob McPherson, spokesperson of the ATLAS Canada collaboration, a professor of physics at the University of Victoria and Institute of Particle Physics scientist. “Its existence was predicted in 1964 when theorists reconciled how massive particles came into being. It took almost half a century to confirm the detailed predictions of the theories in a succession of experiments, and finally to discover the Higgs Boson itself using our 2012 data.”
The Brout-Englert-Higgs (BEH) mechanism was first proposed in 1964 in two papers published independently, the first by Belgian physicists Robert Brout and François Englert, and the second by British physicist Peter Higgs. It explains how the force responsible for beta decay is much weaker than electromagnetism, but is better known as the mechanism that endows fundamental particles with mass. A third paper, published by Americans Gerald Guralnik and Carl Hagen with their British colleague Tom Kibble further contributed to the development of the new idea, which now forms an essential part of the Standard Model of particle physics. As was pointed out by Higgs, a key prediction of the idea is the existence of a massive boson of a new type, which was discovered by the ATLAS and CMS experiments at CERN in 2012.
The next step will be to determine the precise nature of the Higgs particle and its significance for our understanding of the universe. Are its properties as expected for the Higgs boson predicted by the Standard Model of particle physics? Or is it something more exotic? The Standard Model describes the fundamental particles from which we, and every visible thing
in the universe, are made, and the forces acting between them. All the matter that we can see, however, appears to be no more than about 4% of the total. A more exotic version of the Higgs particle could be a bridge to understanding the 96% of the universe that remains obscure.
TRIUMF salutes Peter Higgs and François Englert for their groundbreaking work recognized by today’s Nobel Prize and congratulates the international team of tens of thousands of scientists, engineers, students, and many more from around the world who helped make the discovery.

While I know Canadians have been part of the multi-year, multi-country effort to determine the existence or non-existence of the Higgs Boson and much more in the field of particle physics, I would prefer we were not described as “… Key Part of Historical Nobel Prize … .” The question that springs to mind is: how were Canadian efforts key to this work? The answer is not revealed in the news release, which suggests that the claim may be a little overstated. On the other hand, I do like the bit about ‘saluting Higgs and Englert for their groundbreaking work’.
As for TRIUMF and what appears to be a series of name changes, I’m left somewhat puzzled, This Oct. 8, 2013 news release bears the name (or perhaps it’s a motto or tagline of some sort?): TRIUMF — Accelerating Science for Canada, meanwhile the website still sports this: TRIUMF Canada’s national laboratory for particle and nuclear physics while a July 17, 2013 TRIUMF news release gloried in this name: TRIUMF Accelerators, Inc., (noted in my July 18, 2013 posting). Perhaps TRIUMF is trying to follow in CERN’s footsteps. CERN was once known as the ‘European particle physics laboratory’ but is now known as the European Organization for Nuclear Research and seems to also have the tagline: ‘Accelerating science’.
