Scientists hunting the elusive subatomic 'Higgs' particle will unveil
findings on Wednesday(04-july-2012) that take them nearer to
understanding how the Big Bang at the dawn of time gave rise to stars,
planets and even life.
Physicists who have been smashing particles together near light-speed
at the CERN laboratory near Geneva have already seen tantalising
glimpses of the "Higgs boson", the missing piece of the fundamental
theory of physics known as the Standard Model.
The world of science now awaits a mass of evidence big enough to be
deemed a formal discovery. The secrecy surrounding Wednesday's
announcement has fuelled speculation that nearly 40 years of research
have reached a climax.
Data harvested from CERN's Large Hadron Collider, the biggest particle
accelerator in the world, could also shed light on the make-up of the
poorly understood 'dark matter' and "dark energy" that make up 96
percent of the universe. It may even point the way to research into
the possibility of parallel universes.
CERN is planning to beam the announcement live around the world to a
physics conference in Melbourne, Australia. Related events are planned
in countries involved in the project, including Britain. The unusual
level of stage management has fuelled the sense that big news is on
the cards.
On Monday, US physicists said they had found the strongest evidence
yet of the existence of the Higgs in a mass of data collected from the
now-mothballed Tevatron particle accelerator, run by the Fermi
National Accelerator Lab outside Chicago.
"It will be interesting to see how it lines up with CERN's results on
Wednesday," said CERN spokesman James Gillies.
Some scientists working on the project have told Reuters they expect
the unveiling of a formal discovery while others expect it to fall
just short.
With thousands of physicists involved, divided into two separate teams
called Atlas and CMS, CERN insists the full picture will not be clear
to anyone until a seminar shortly before Wednesday's announcement.
"Even CERN's director general won't know much before the seminar
reveals the exact results," said Pauline Gagnon, a Canadian particle
physicist working on Atlas. "They are being finalised at the last
minute after much scrutiny."
The Higgs particle, although crucial for understanding how the
universe was formed, remains theoretical. It is the last undiscovered
piece of the Standard Model that describes the fundamental make-up of
the universe. The model is for physicists what the theory of evolution
is for biologists.
Scientists say the existence of dark matter and dark energy suggests
the Standard Model, if validated by a Higgs discovery, is just the
first layer of a more complex theory that includes the vast bulk of
the universe that is now poorly understood.
"The Standard Model has a few major flaws; the Higgs boson discovery
would only fix one of them," said Gagnon.
"We still have no clue regarding what makes 96 percent of the content
of the universe. This should keep us physicists busy for a few more
decades."
