Press Release

Tevatron experiments report latest results in search for Higgs boson

Editor's note: A special Joint Experimental Theoretical Physics Seminar will take place today at 2 p.m. in Ramsey Auditorium. Satish Desai will give a talk titled, "Latest Higgs Results from DZero," and Michelle Stancari will give a talk titled, "Latest Higgs Results from CDF and Tevatron Combination." Both will be streamed live online.

Using different search techniques, physicists see hints of Higgs boson sighting consistent with those from LHC

New measurements announced today by scientists from the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory indicate that the elusive Higgs boson may nearly be cornered. After analyzing the full data set from the Tevatron accelerator, which completed its last run in September 2011, the two independent experiments see hints of a Higgs boson.

Physicists from the CDF and DZero collaborations found excesses in their data that might be interpreted as coming from a Higgs boson with a mass in the region of 115 to 135 GeV. In this range, the new result has a probability of being due to a statistical fluctuation at level of significance known among scientists as 2.2 sigma. This new result also excludes the possibility of the Higgs having a mass in the range from 147 to 179 GeV.

Physicists claim evidence of a new particle only if the probability that the data could be due to a statistical fluctuation is less than 1 in 740, or three sigmas. A discovery is claimed only if that probability is less than 1 in 3.5 million, or five sigmas.

Frequently asked questions about the Higgs boson

Each time news comes out about the Higgs boson I get questions from media, friends and family trying to grasp why this particle is so important. The following questions come up again and again. So with experimenters from using Fermilab's Tevatron announcing new Higgs results Wednesday at a conference in Italy, I thought it was time to share answers to the questions that might pop into your mind.

Why should the average person care if the Higgs is found?

Understanding more about the building blocks of matter and the forces that control their interactions helps scientists to learn how to manipulate those forces to humankind's benefit. For example, the study of the electron led to the development of electricity, the study of quantum mechanics made possible the creation of GPS systems and the study of the weak force led to an understanding of radioactive decay and nuclear power.

Now what?

The Tevatron experiments will continue to further analyze the Higgs boson data to wring out more information.

Data hint at hypothetical particle, key to mass in the universe

From The New York Times,
March 7, 2012

After 40 years, more evidence is being reported Wednesday that the end of the biggest manhunt in the history of physics might finally be in sight.

Physicists from the Fermi National Accelerator Laboratory in Batavia, Ill., say they have found a bump in their data that might be the long-sought Higgs boson, a hypothesized particle that is responsible for endowing other elementary particles with mass.

The signal, in data collected over the last several years at Fermilab's Tevatron accelerator, agrees roughly with results announced last December from two independent experimental groups working at the Large Hadron Collider at CERN, the European Organization for Nuclear Research, outside Geneva.

"Based on the current Tevatron data and results compiled through December 2011 by other experiments, this is the strongest hint of the existence of a Higgs boson," said the report, which will be presented on Wednesday by Wade Fisher of Michigan State University to a physics conference in La Thuile, Italy.

Upcoming construction

Kent Collins

Kent Collins, deputy head of the Facilities Engineering Services Section, wrote this column.

Chicago weather is often said to have two seasons – winter and construction. This year, we didn't experience a harsh winter and, for the most part, construction work continued. As spring approaches, there are several new projects starting that will affect us as we commute to and from work.

The road reconstruction, utility relocation and repair and the parking lot project between the Industrial Buildings and the CDF area are almost complete. The construction contract for the Illinois Accelerator Research Center's Office, Technology and Education Building (IARC OTE) is out for bid now, with construction starting this spring and finishing in late October of 2013.

Road D will remain open during the OTE Building construction, but there may be occasional short-term traffic interruptions as equipment and materials are moved to the construction site.

Realignment and paving of the main intersection of Pine Street and Roads A1/A2 at the north end of the Wilson Hall reflecting ponds is scheduled to start in late April. Road D will be repaved from the intersection to FCC, and there will be several phases that will reroute traffic around the area for weeks at a time. Watch for announcements in Fermilab Today as each phase approaches.

The Wilson Hall safety improvements project will continue through summer, with the West stairway closed until summer. The East stairway will be closed during the summer and opened in the fall .

At the end of summer, FESS will be repaving a substantial section of Batavia Road east of Eola Road. By paving one lane at a time, the Roads and Grounds group will be able to accomplish this project with minimal traffic delays.

Construction of the deep underground NOvA Near Detector Hall, scheduled for this summer, will require trucking excavated material from the Service Building area to the south end of Kautz Road.

Please watch for announcements in Fermilab Today for more information about each construction project.

Special Announcement

Short-Baseline Neutrino Experiments - Needs and Options meeting - March 21

There will be a Short-Baseline Neutrino Experiments - Needs and Options meeting on Wednesday, March 21, from 9 a.m. to 6 p.m. in One West. This meeting was organized to facilitate discussion between the neutrino community and the newly formed "Short-Baseline Neutrino Focus Group" at Fermilab.
