The University of Texas at
Arlington will host hundreds of particle physicists from all over the world Oct.
22-26 for the International
Workshop on Future Linear Colliders.
The meeting is being held in
Texas for the first time. It will feature a public lecture by Nobel
Prize-winning physicist Steven Weinberg titled “The Standard
Model, Higgs Boson, Who cares?” at 7:30 p.m., Oct. 24, on the UT Arlington
The semiannual conference has
added significance because of a July 4 announcement from researchers at the
Large Hadron Collider at the European Center for Nuclear Research, or CERN, that
they’ve almost certainly found the elusive Higgs boson.
As the next step in discovery, the
proposed International Linear Collider,
or ILC, will be a 31-kilometer-long electron-positron collider to complement and
expand the work of the proton-proton colliding LHC, said Jaehoon Yu, UT
Arlington physics professor and
co-organizer of the event.
“This summer’s announcement of a
Higgs-like particle allows us to take the linear collider idea to the next
level,” Yu said. “The mass range where scientists at CERN believe they have
found the Higgs boson – around 126 gigaelectronvolts or GeV – is well
within the capabilities of the first phase of the planned ILC.”
Yu added: “With the
ability to collide beams of particles 14,000 times every second at energies as
high as 500 GeV, the linear collider could give us a host of new information
about this new particle and help address other mysteries such as dark matter
and dark energy.”
interaction with the Higgs boson gives particles in the universe their mass. It
is sometimes referred to as the “God particle” in the media. The Higgs is the
only particle in the Standard Model of particle physics that has not been
observed. The Standard Model describes the basic forces and interactions
between the fundamental particles.

Scientists at the October
gathering will discuss concepts for the ILC, which consists of two linear
accelerators that face each other, and the Compact Linear Collider, another
potential project being studied at CERN. Both colliders would ultimately reach energies
of 1 TeV (trillion electron volts) or more.
The U.S. Department of Energy is
providing funding for the conference, which is co-sponsored by the
International Committee for Future Accelerators, the International Linear
Collider, the Compact Linear Collider Study and the Worldwide Study of Physics
and Detectors for future linear e+ e- colliders.
Yu and other scientists from UT
Arlington’s Center of Excellence for High Energy Physics have worked on the
Large Hadron Collider for more than a decade. Yu and fellow UT Arlington
physics professor Andrew White are also heavily involved in plans for the International
Linear Collider, which is estimated to be a $10 billion project that would take
a decade to build.
“Members of the UT Arlington
faculty have a long history of making sure the University is engaged at the
highest level in high-energy physics research,” said Carolyn Cason, UT
Arlington’s interim vice president for research. “The International Workshop
planned for October will continue that tradition and bring some of the
brightest scientist in the world to North Texas.”
