New sustainability website and symbol

A new website on sustainability initiatives at Fermilab launched recently, complete with a new symbol, above. Click to enlarge; feel free to display the symbol in your work area.

Fermilab has a new website dedicated to informing the public on sustainability efforts around the lab. It can be found on the homepage under the link "About Fermilab" or here:

The website highlights Fermilab's sustainable work in eight areas: electronics stewardship, energy and water conservation, greenhouse gas reduction, green purchasing, high-performance sustainable buildings, land stewardship, pollution prevention and transportation. There is also a section called "For Employees" where links for useful tools and information are located. The "Green at the Roots" page displays stories of employees' "home-grown" efforts to make their work more sustainable or environmentally friendly. If you or a coworker has gone the extra mile for the environment, please send an e-mail with a short description and photo to Katie Kosirog at

Another feature for Fermilab employees to take advantage of is the GreenRide Connect program, which allows employees to log their commuting habits to determine associated greenhouse gas emissions, track cost savings or sign up for a carpooling group. Fermilab is currently partnering with Argonne for this program. Follow the link from the new website or register here.

Visual Media Services has created a new symbol to represent sustainability at Fermilab, shown above. Feel free to display this symbol in your own work area for purposes such as a designating a recycling area, encouraging others to reuse equipment before purchasing new replacements or displaying green products in use.

In Brief

Snowmass Young survey for high-energy physicists online

The Snowmass Young survey is far more exciting than this.

The Snowmass Young Physicists' survey for past, current and future participants in the field high-energy physics is now online. Survey results will be presented at the upcoming Snowmass conference this summer.

The Snowmass Young survey is intended for anyone who is currently in high-energy physics or who has worked in HEP at one time in his or her career. It is also for young scientists in training who are considering going into HEP. Undergraduates, graduates, postdocs, staff scientists, faculty and researchers are encouraged to take the survey. Those who trained in high-energy physics and then decided to work outside HEP are especially encouraged to take it.

The brief survey should take 10 to 20 minutes to complete. Snowmass Young Physicists' goal is to hear from 1,500 respondents from the various frontiers of particle physics as defined in the Snowmass process as well as from those who are currently outside HEP.

Take the survey and learn more about the Snowmass Young Physicists Movement.

Obama's 2014 science budget

From Science, April 10, 2013

The details have not yet been released, but the proposed 2014 budget for the Department of Energy (DOE) appears to be a researcher's dream. DOE's basic research arm, the Office of Science would get a 5.7% increase from the level enacted for fiscal 2012—the last budget that Congress passed—to $5.15 billion. (Last month, Congress essentially extended the 2012 budget through the rest of fiscal year 2013, which ends on 30 September.)

SDSC's Gordon supercomputer assists in crunching Large Hadron Collider data

From San Diego Supercomputer Center News Center, April 4, 2013

Gordon, the unique supercomputer launched last year by the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, recently completed its most data-intensive task so far: rapidly processing raw data from almost one billion particle collisions as part of a project to help define the future research agenda for the Large Hadron Collider (LHC).

Search for supersymmetry's John Hancock

Production of the SUSY particles searched for in this analysis. The red circles are the incoming proton and antiproton, the blue circles are the SUSY particles, and the gold circles are the leptons. From the three charged leptons we find a like-sign pair. The dashed circles show invisible particles.

As is the case in historical documents, in particle physics there are signatures, and then there are signatures. Physicists at the Tevatron and the Large Hadron Collider spend countless hours devising the perfect searches for exotic new particles. They then pore over the trillions of events collected by the gigantic experiments at these colliders looking for the telltale event characteristics, or signatures, that would indicate the discovery of a new fundamental particle.

Supersymmetry (SUSY to her friends) is an intriguing theory that has been at the top of the high-energy physics Most Wanted list for a few decades now. It boldly states that all the leptons, quarks, gauge bosons (such as the photon) and the Higgs account for merely half of the true slate of fundamental particles of nature. Doubling the list would yield truly remarkable consequences. For starters, SUSY makes the Higgs more stable and provides a dark-matter particle.

Physicists at the Tevatron's CDF experiment have searched large data sets for SUSY using the John Hancock of signatures. They look for events with two leptons, where lepton refers to an electron, muon or tau. While many Standard Model (SM) processes yield dileptons, this search requires the leptons have like-sign electric charge. Thus, a positron and a positively charged tau (e+τ+) is okay, but a positron and a negatively charged tau (e+τ-) isn't. This requirement removes the lion's share of the SM backgrounds but would keep much of the SUSY signal. Thus, seeing a preponderance of like-sign events would be a clear indication something exciting was afoot, for example, the production of two SUSY particles, the chargino and neutralino (see top figure). Furthermore, this search adds the additional requirement that one of the leptons be a tau particle, as previous searches for SUSY from the Tevatron and LHC indicate that looking for the tau might be a crucial ingredient for success.

Unfortunately, a careful comparison between the data and the expectations from the SM and SUSY predictions indicates that Hancock is still at large (see bottom figure). For the time being, the Standard Model is safe! Nevertheless, particle physicists at the Tevatron, the LHC and beyond, will continue the hunt for new particles knowing that any discovery will teach us something fundamental about our universe.

The invisible particles exit the detector with no interaction. This results in missing transverse energy, which is shown in this figure. The SUSY signal would give an enhancement at high values (shown in red), but the CDF data agree with the Standard Model prediction.
Physicists Robert Forrest, now at Stanford, and Maxwell Chertok, University of California, Davis, were responsible for this analysis.
