Elusive Higgs boson in sight?

08.03.2012
After 40 years of searching, physicists have the elusive Higgs boson in their sights. Wade Fisher, Michigan State University assistant professor of physics, presented the team’s results today at a physics conference in La Thuile, Italy.

The Higgs boson is a hypothetical particle thought responsible for giving mass to matter, a critical but still unproven component of the long-standing Standard Model of particle physics.

If a Higgs boson is created in a high-energy particle collision, it immediately decays into lighter more stable particles before even the world’s best detectors and fastest computers can snap a picture of it.

To find one, physicists retraced the path of these secondary particles and ruled out processes that mimic its signal. Fisher, who coordinates the Collider Detector at Fermilab and DZero teams at the Department of Energy’s Fermi National Accelerator Laboratory, however, suggests the elusive Higgs boson may nearly be cornered.

“We see a distinct Higgs-like signature that cannot be easily explained without the presence of something new,” Fisher said. “If what we're seeing really is the Higgs boson, it will be a major milestone for the world physics community and will place the keystone in the most successful particle physics theory in history."

The results, which have been collected over several years at Fermilab, are similar to those found by teams working at the Large Hadron Collider at CERN, the European Organization for Nuclear Research. But even though the results are close, scientists are not quite ready to claim a definitive discovery, said Dmitri Denisov, a DZero spokesperson and physicist at Fermilab.

“There is still much work ahead before the scientific community can say for sure whether the Higgs boson exists,” he said. “Based on these exciting hints, we are working as quickly as possible to further improve our analysis methods and squeeze the last ounce out of our data.”

CDF is an international experiment of 430 physicists from 58 institutions in 15 countries. DZero is an international experiment conducted by 446 physicists from 82 institutions in 18 countries. Funding for both experiments come from DOE's Office of Science, the National Science Foundation and a number of international funding agencies.

Michigan State University has been working to advance the common good in uncommon ways for more than 150 years. One of the top research universities in the world, MSU focuses its vast resources on creating solutions to some of the world’s most pressing challenges, while providing life-changing opportunities to a diverse and inclusive academic community through more than 200 programs of study in 17 degree-granting colleges.

Im Focus: A miniature stretchable pump for the next generation of soft robots

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.

Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...

Im Focus: Vehicle Emissions: New sensor technology to improve air quality in cities

Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.

Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...

Im Focus: Self healing robots that "feel pain"

Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.

Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...

Im Focus: Scientists create the world's thinnest gold

Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.

The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...

Im Focus: Study on attosecond timescale casts new light on electron dynamics in transition metals

An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.

The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
