Northeastern Plays Key Role in DZero International Physics Research Collaboration

06.08.2008
Darien Wood, Ph.D., Associate Professor of Physics at Northeastern University, and other researchers from Northeastern have played integral roles in the recent discovery of the production of pairs of Z bosons, or ZZ dibosons, at the Tevatron particle accelerator.

As the co-leader of the DZero project, Wood led a team of scientists who recently announced the observation of previously unobservable ZZ diboson particles.

The properties of the ZZ diboson make its discovery a necessary precursor to determining whether the Higgs boson does indeed exist. The Higgs boson is the only hypothetical particle in the Standard Model of particle physics that has not yet been observed.

DZero is an international collaboration of 600 scientists from 90 institutions in 18 countries who conduct physics research at Tevatron, currently the world’s highest energy particle accelerator. The experiments explore matter by creating an environment where they can observe interactions of protons and antiprotons, which they hope will lead to a better understanding of the fundamentals of matter and our universe. Tevatron is located in Batavia, IL at the Fermi National Accelerator Laboratory, a United States Department of Energy laboratory.

The scientists set out to examine particle collisions at high energies to see what interactions occur. The scientists developed tools to detect the presence of ZZ dibosons, an extremely rare occurrence, from their decays into electrons, muons, and neutrinos. Despite being difficult to detect, the team was able to observe the ZZ dibosons in three proton-antiproton collisions out of more than 200 trillion.

The final analysis, accomplished by a team of 11 physicists – five of whom are from Northeastern – brought this result to its completion. In addition to Prof. Wood, the Northeastern team included Associate Professor Emanuela Barberis, Ph.D., Postdoctoral research associates Gianluca Cerminara, Ph.D., and Gavin Hesketh, Ph.D., and graduate student Gabriel Facini, all in the physics department. The other schools involved with the final analysis included SUNY – Stony Brook, the University of Manchester, SUNY – Buffalo and the Institute of High Energy Physics, Russia.

“This result is very exciting and it is one of the last stepping stones on the route to possible detection of the elusive Higgs boson,” said Wood.

About Northeastern
Founded in 1898, Northeastern University is a private research university located in the heart of Boston. Northeastern is a leader in interdisciplinary research, urban engagement, and the integration of classroom learning with real-world experience. The university’s distinctive cooperative education program, where students alternate semesters of full-time study with semesters of paid work in fields relevant to their professional interests and major, is one of the largest and most innovative in the world. The University offers a comprehensive range of undergraduate and graduate programs leading to degrees through the doctorate in six undergraduate colleges, eight graduate schools, and two part-time divisions.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
