LBNE gains new partners from Brazil, Italy and UK

LBNE is making headway toward becoming a truly global experiment.

Last week 16 institutions from Brazil, Italy and the UK joined the LBNE collaboration, based at Fermilab, significantly contributing to an overall membership increase of over 30 percent compared to a year ago.

The swelling numbers strengthen the case to pursue an LBNE design that will maximize its scientific impact, helping us understand how neutrinos fit into our understanding of matter, energy, space and time.

In mid-2012 an external review panel recommended phasing LBNE to meet DOE budget constraints. In December the project received CD-1 approval on its phase 1 design, which excluded both the near detector and an underground location for the far detector.

"Although LBNE was reconfigured for CD-1, our goal is still to deliver a full-scope, fully capable LBNE to enable world-leading physics," Project Director Jim Strait told the LBNE collaboration earlier this month at its meeting in Fort Collins, Colo. "We have a well-developed design of such a facility, and we are working with new partners to move toward this goal."

Fortunately, the CD-1 approval explicitly allows for an increase in design scope if new partners are able to bring additional resources. Under this scenario, goals for a new, expanded LBNE phase 1 bring back these excluded design elements, which are crucial for executing a robust and far-reaching neutrino, nucleon decay and astroparticle physics program.

Over the last few months, neutrino physicists from institutions in several countries have expressed interest in joining LBNE. Discussions are under way to identify areas of mutual interest and understanding the potential scale of collaboration.

"These groups bring a wealth of physics and technology expertise to the collaboration," said Bob Wilson of Colorado State University, who, with fellow spokesperson Milind Diwan of Brookhaven National Laboratory and others, has been actively building these partnerships.

Physicist Ricardo Gomes of the Federal University of Goiás in Brazil, whose group is already a member of the MINOS+ and NOvA experiments, said that LBNE is a natural next step.

"LBNE is a great opportunity to work on an exciting experiment from the start, one that will help to answer important neutrino questions," Gomes said. "We hope to work on simulation of background events from cosmic-ray muons and would like to contribute to the photon detector instrumentation."

Fermilab Director Nigel Lockyer is pleased with LBNE's recent growth.

"It's incredibly encouraging that so many around the globe are signing on as official LBNE collaborators," Lockyer said. "To get as much science as we can out of it, LBNE must be a global project."

Meet the 2013-14 Users Executive Committee

Fermilab users recently elected six new officers to the Users Executive Committee for the 2013-14 term. The UEC handles the affairs of the Fermilab Users Organization. It provides a forum for discussion of scientific and administrative matters relevant to the organization and functions of the laboratory. Members of the UEC serve as a communication channel between the Fermilab user community and laboratory management. UEC members also participate in public outreach and quality-of-life activities, organize visits to congressional offices and coordinate the annual Fermilab Users Meeting.

What do you find when you crowdsource the universe?

From The Christian Science Monitor, Sept. 24, 2013

How many people does it take to catalogue 300,000 galaxies?

Well, about 83,000, scientists say.

Astronomers at the University of Minnesota reported this week that contributors to the citizen science portal, Galaxy Zoo, had helped them to amass a database of galaxies some 10 times larger than any previous galaxies catalog. The new catalog is described in a paper published in the Monthly Notices of the Royal Astronomical Society and is also available to the public online.

Galaxy Zoo debuted in 2007 on the citizen science interface, which is now host to some 18 citizen science projects that offer almost 900,000 budding scientists the chance to sift through the universe, be it at the macro level, as a galaxy hunter, or at the most micro of micro levels: last week, the interface pushed the latest project live, called Plankton Portal. That project, out of Oregon State University and the University of Miami, asks for the public's help in characterizing the beguiling plankton – jellyfish included! – seen in about a million underwater images.

To date, 54 scientific papers have been published based on Zooniverse's crowd-sourced data.

Frontier Science Result: DZero

X marks the what?

The peak on the left indicates an excess of events consistent with the X(4140) state, which could be a new type of particle composed of two quarks and two antiquarks. A second possible excess can also be seen, although this is more consistent with a background fluctuation.

Physicists at particle colliders often perform searches for specific particles that are predicted to exist in our models. The Higgs boson is an excellent example of such a focused search effort, and indeed we found it in the end! However, this isn't always the way that science works. Sometimes there are surprises, discoveries of new particles that aren't expected and that don't fit within our existing theories. Such findings can challenge our understanding of the universe.

In recent years, there have been several observations and hints of this kind: a class of particle that appears to stretch our comprehension of the way that quarks interact. We currently know of only two ways that quarks combine into composite particles, either in quark-antiquark pairs ("mesons") or in threesomes ("baryons") like the proton. The "new" particles behave like mesons, but their properties show that there must be some other quarks inside as well: We could be seeing four-quark states for the first time! These unexpected particles are so mysterious that they are called simply X, Y or Z states in the official listings, and scientists are working hard to understand and identify them more fully.

Inspired by one of these hints from the CDF collaboration, a new search at the DZero experiment looks for the snappily named X(4140) state decaying into a charm-anticharm meson and a strange-antistrange meson. The analyzers indeed see an excess of possible signal events, sharply peaked in mass, consistent with this fledgling state, with less than a 0.3 percent chance that it is a natural fluctuation of background events.

Interestingly, while the CDF and DZero results agree, additional searches from other experiments in Europe and Japan give inconclusive results, and so the X(4140) enigma goes on: Further work is needed before the state can be confirmed. This shows the value of building and operating independent experiments, allowing measurements like this to be cross-checked and fully investigated. By combining information from all the different particle accelerators, we hope to compile a list of these "exotic" end-of-alphabet states and maybe even add a third sibling to the meson and baryon family.

Special Announcement

Relocation of Wilson Hall offices

By the end of the calendar year, the offices of the Fermilab director, deputy director and chief operating officer will relocate to the first floor on the west side of the Wilson Hall atrium. The International Services Office is being relocated to accommodate the construction work. Tomorrow, Sept. 27, the Visa Office will move to the west side of the 15th floor. On Tuesday, Oct. 1, the Users Office, Pilot's Leasing and the Fermilab Box Office will be relocated to the One North conference room. Services may be limited on move days, so please plan accordingly.
