In Brief

Sitewide domestic water flush – June 29-30

A sitewide domestic water flush will take place on Saturday and Sunday. Photo courtesy of Steve Shirley, FESS

FESS Operations has tentatively scheduled a sitewide domestic water flush for Saturday, June 29, and Sunday, June 30, with rain dates of July 13 and 14. This annual event starts at approximately 6 a.m. and ends at roughly 6 p.m. each day.

During this time it is not unusual to notice an excessive amount of water on the roadways, standing puddles around fire and flushing hydrants, lower-than-normal domestic water pressure, discoloration in the water and, for those monitoring the facility incident reporting and utility system, low-pressure alarms as well. Typically, not long after each area has been flushed, the water pressure returns and discoloration clears up. In previous years, this process has had no ill effects on laboratory operations, and we anticipate this year to be the same.

FESS Operations asks everyone to be mindful of personnel performing the flushing during the above-mentioned dates, as a portion of their work will be performed in the roadways around Fermilab. Thank you for your consideration during this time.

Particle pals: neutrino experiment shows protons and neutrons pairing up

From Scientific American, June 24, 2013

Neutrinos are notoriously antisocial, nearly always slipping past atoms of matter without so much as a "how do you do." But new research indicates that on the rare occasion a neutrino and an atomic nucleus do make contact, the interaction is surprisingly involved.

By training a beam of neutrinos on a plastic target, researchers at the MINERvA experiment at Fermi National Accelerator Laboratory in Batavia, Ill., have found that when a neutrino collides with an atom it often knocks free not just one proton or neutron, but two. Some of the particles within the atomic nuclei, it appears, are pairing up rather than moving about independently, only to be sprung free in twos when a neutrino strikes. The results will have implications for precision neutrino measurements, which often rely on carefully reconstructing the physics of rare collisions between neutrinos and atoms.

Physicists find new particle, look for answers

From Talk of the Nation, June 21, 2013

Researchers say that they've discovered a new subatomic particle—one that appears to contain four quarks bound together. Physicist Sean M. Carroll describes the significance of the find and talks about the ongoing effort in physics to explain why the universe is the way it is.

Frontier Science Result: DZero

Evidence of truth and beauty production

Rare processes that produce a single top quark at a time can give insight into the nature of the weak force.

Albert Einstein once stated, "The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives." A recent analysis at DZero takes his advice in a literal search for truth and beauty.

While top quarks are most commonly produced in pairs via the strong force, the W boson, a weak force carrier, will rarely decay into a solitary top quark (also known as a truth quark) and a bottom (or beauty) quark. Certain models of new physics predict that this mode of single-top quark production would be enhanced with respect to the Standard Model. By taking Einstein's advice, DZero analyzers aim to uncover truth and beauty in the universe by observing the simultaneous production of truth and beauty quarks.

Quarks made in a collision turn into sprays, or jets, of particles. Jets produced from a bottom quark can be identified because they tend to be offset by a couple millimeters from the rest of the particles produced in an event. After selecting events that include a W boson signature and bottom quark jets, there are nearly 50 times as many background events as signal. To enhance the sensitivity of their analysis, the analyzers used three independent advanced techniques to discriminate signal from background and then combined the output of all three into a final powerful discriminant.

After examining the DZero Run II data, the analyzers found a significant excess of events above the background prediction and report the first evidence for this mode of single-top quark production. In addition, they presented an improved measurement of another production mode, in which the top and bottom quarks are accompanied by a third quark, and refined an independent measurement of the way the weak force interacts with top and bottom quarks. As part of the legacy of Einstein's appeal to our curiosity, these new measurements of truth and beauty become part of the Tevatron's legacy and provide important constraints on future models of new physics.

Mike Cooke

These physicists made major contributions to this analysis.
Many analyses, like the one above, rely on the DZero b-jet identification group in order to select events that have jets that originated from bottom quarks.
