Fermilab Press Release

Fermilab experiments narrow allowed mass range for Higgs boson

Scientists from the CDF and DZero collaborations at DOE's Fermilab have combined Tevatron data from their two experiments to increase the sensitivity for their search for the Higgs boson. While no Higgs boson has been found yet, the results announced today exclude a mass for the Higgs between 158 and 175 GeV/c2.

New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab revealed their latest Higgs search results today (July 26) at the International Conference on High Energy Physics, held in Paris from July 22-28. Their results rule out a significant fraction of the allowed mass range established by earlier experiments.

The Fermilab experiments now exclude a Higgs particle with a mass between 158 and 175 GeV/c2. Searches by previous experiments and constraints due to the Standard Model of Particles and Forces indicate that the Higgs particle should have a mass between 114 and 185 GeV/c2. For comparison: 100 GeV/c2 is equivalent to 107 times the mass of a proton.) The new Fermilab result rules out about a quarter of the expected Higgs mass range.

"Fermilab has pushed the productivity of the Tevatron collider to new heights," said Dennis Kovar, DOE Associate Director of Science for High Energy Physics. "Thanks to the extraordinary performance of Fermilab's Tevatron collider, CDF and DZero collaborators from around the world are producing exciting results and are making immense progress on the search for the Higgs particle."

At the ICHEP conference, CDF and DZero scientists are giving more than 40 talks on searches for exotic particles and dark matter candidates, discoveries of new decay channels of known particles and precision measurements of numerous particle properties. Together, the two collaborations present about 150 results.

The Higgs particle is the last not-yet-observed piece of the theoretical framework known as the Standard Model of Particles and Forces. According to the Standard Model, the Higgs boson explains why some particles have mass and others do not.

"We are close to completely ruling out a Higgs boson with a large mass," said DZero co-spokesperson Dmitri Denisov, one of 500 scientists from 19 countries working on the DZero experiment. "Three years ago, we would not have thought that this would be possible. With more data coming in, our experiments are beginning to be sensitive to a low-mass Higgs boson."

Robert Roser, co-spokesperson for the 550 physicists from 13 countries of the CDF collaboration, also credited the great work of the CDF and DZero analysis groups for the stringent Higgs exclusion results.

Senate Appropriations Committee report language details DOE funding bill

From FYI: The AIP Bulletin of Science Policy News, July 23, 2010

Yesterday the full Senate Appropriations Committee approved the FY 2011 Energy and Water Development Appropriations bill. Accompanying S. 3635 is a report providing specific program recommendations. Below are selections from this report language. While the counterpart House subcommittee has approved its FY 2011 funding bill its report will not be released until the measure is considered by the full House Appropriations Committee. Senate Report 111-228, is available at this web site.

Office of Science:
FY 2010 appropriation: $4,903.8 million
FY 2011 Administration request: $5,121.4 million
House subcommittee recommendation: $4,900 million, a decline of $4 million or 0.1 percent below this year.
Senate subcommittee recommendation: $5,012.0 million, an increase of $108.2 million or 2.2 percent above this year.

ES&H Tips of the Week - Safety safety

Choosing proper work footwear

Flip-flop shoes such as those in the photo above are not safe work attire. They offer little or no protection, minimal cushioning and no arch support. In addition, walking in these types of shoes requires an unnatural toe-gripping gait.

Fermilab's Medical Department has seen a large number of injuries associated with footwear choices during summer months. These injuries involved individuals wearing shoes that provide little protection or support, are hard to walk in or are ill-fitting.

Here are some guidelines from the American Podiatric Medical Association to help prevent shoe-related injuries:

  • Choose footwear that provides protection from anticipated occupational hazards, such as falling or sharp objects.
  • Wear shoes with a low heel to reduce leg and back strain and to prevent slips, trips and falls.
  • High-heeled shoes shorten calf muscles, contribute to knee and back problems and increase the risk of falling. If you wear heels, choose styles with squared-off toes and shorter, chunkier heels.
  • Choose shoes that fit well. Shoes that do not fit correctly can cause blisters and contribute to injuries.
  • Avoid wearing the same pair of shoes for multiple days in a row. Alternating pairs of shoes protects your feet from repetitive stress and allows shoes to dry between wearing.
  • Discard shoes that are worn out or have thin soles. Worn out shoes require more energy to walk. These shoes have a greater impact on your feet and reduce the stability of your lower legs. Worn-out shoes also have little shock absorption quality.

If you need protective safety footwear for work, talk to your supervisor. Fermilab does have a protective footwear program. The form used to order protective footwear is located on the ES&H website.
