Government reopens Thursday after Congress passes budget deal, raises debt limit

From The Washington Post, Oct. 17, 2013

Federal agencies, parks, museums and monuments began to reopen Thursday morning, after a chastened Congress ended a bitter spending standoff that triggered a 16-day government closure and drove the nation toward the brink of default.

The Senate and the House voted late Wednesday to fund agencies, call hundreds of thousands of civil servants back to work and raise the $16.7 trillion debt limit.

In Brief

Winter wear donations collected through Oct. 31

Do you have new or gently used coats, hats or gloves you're willing to donate? If so, drop off your winter outerwear in one of the Winter Coat Exchange donation boxes located throughout Fermilab by Oct. 31.

Helping Hands, an outreach committee formed by the Equal Opportunity and Diversity Office, is continuing to accept new or gently used winter outerwear for its winter coat exchange. Employees, users and visitors are encouraged to donate coats, hats and gloves for women, men and children. Collection boxes are located throughout the Fermilab campus, and collection ends on Oct. 31.

On Nov. 13 and 14 from 3-6 p.m. in the Small Dining Room, the Fermilab community will have the opportunity to select items from those collected. Items not selected will be donated to the Batavia Interfaith Food Pantry and Clothes Closet. For more information, view this flyer or contact Samantha Poeppelman at x3933 or at

In Brief

Now accepting applications for Wilson Fellowship

The Wilson Fellowship committee at Fermilab seeks applications from Ph.D. physicists of exceptional talent with at least two years of postdoctoral experience. The fellowship is awarded on a competitive basis and is intended to support strong, assistant-professor-level physicists early in their careers. It provides unique opportunities for self-directed research in experimental physics through work on the Fermilab particle physics experiment of the candidate's choice. The Fermilab experimental program includes collider physics, studies of neutrino, muon and astroparticle physics, and R&D and planning for experiments at future colliders and with high-intensity beams.

The Wilson Fellowship provides an annual salary fully competitive with a university assistant professorship. The appointment is for an initial term of three years, and the possibility exists for renewal for an additional two years upon completion of a successful review after the first two years. Thereafter, the potential exists for eventual appointment without term limit.

To apply, the candidate should submit a curriculum vitae, a research statement (not to exceed five pages) giving a focused description of his or her proposed research program as a Wilson Fellow and should arrange to have four letters of reference submitted online. The application deadline is Friday, Nov. 1.

Additional information is available at the Wilson Fellowship website. Questions may be submitted via email to

Elsevier announces the launch of the Journal of High Energy Astrophysics

From PR Newswire, Oct. 10, 2013

Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the launch of the Journal of High Energy Astrophysics (JHEAp), the first astrophysical journal that revolves around the study of high energy objects and events.

The Journal of High Energy Astrophysics targets research on energetic phenomena in the universe. Examples of these phenomena include black holes at all scales, neutron stars, pulsars and their nebula, binaries, novae and supernovae, their remnants, active galaxies, and clusters. Launched under favorable conditions, the journal is an attractive addition to the traditional journal landscape in the field. It will offer various gold open access options, embraces the delayed access model, and does not have page charges.

Frontier Science Result: DZero

DZero milestone: 300th Run II publication submitted

DZero has now surpassed 300 publications submitted in Run II. The milestone paper is a comprehensive study of W boson-plus-jet production, pushing our understanding of quark interactions and, in turn, enabling the particle physics community to perform better measurements, including extracting properties of the Higgs boson.

Nine years after the DZero collaboration published their first measurement using Run II Tevatron data, they have now reached the milestone of submitting 300 Run II papers. Considering the amount of effort that goes into each measurement, this is a major achievement and highlights just how much the particle collider experiments at Fermilab have contributed to our understanding of the subatomic world.

The 300th measurement is in itself a landmark analysis, examining in great detail the properties of "W plus jets" events, in which a W boson is produced in conjunction with one or more high-energy particle "jets." Such processes are very important in high-energy particle interactions and provide valuable information on the fundamental processes of quantum chromodynamics, which governs the binding of quarks into bound states such as protons and neutrons.

Perhaps more important still is that such W+jets events are a major background in studies of the Higgs boson, in measurements of top quark properties and in searches for hypothetical supersymmetry signatures. At the Tevatron, for example, for every Higgs boson produced in proton-antiproton collisions, there are many thousand W+jets events: These backgrounds must be understood with high precision in order to pick out the tiny signal. Any improvement in our W+jets models will therefore benefit many important measurements at the Tevatron, the LHC and future collider experiments.

Some of the numbers associated with "paper 300" are startling: From a sample of over two million W boson events, the production properties are examined as a function of more than 25 variables, with one-, two-, three- and four-jet events analyzed separately. For theorists and future experimenters, this represents a highly detailed database, guiding them to better measurements like a roadmap.

Of course, 300 is just a number, and the scientists at DZero didn't stop to admire the view once the paper was submitted. In fact, the Run II submission tally has since reached 316, in addition to 132 papers submitted during Run I. We expect to submit many more in the coming year as we continue to cement the enduring legacy of the Tevatron program.

Mark Williams

The DZero collaboration, still going strong, consists of around 400 scientists from 72 institutions in 18 different countries.
The DZero experiment is a general-purpose detector, comprising many layers that combine to give a complete picture of the particle collisions. Shown here is one such sub-detector: the uranium and liquid-argon calorimeter, which captures almost all the particles produced in the original interaction and measures their energies. This is of great importance for any measurement of events containing particle jets, such as the W+jets paper.
