SeaQuest sees muons

Operators are starting to see muons in the SeaQuest hall.

On Wednesday, March 8, the muon beam from the Main Injector was delivered on target for the SeaQuest experiment. While there's still some work to be done before the beam is ready for production, this achievement marks an important milestone for the SeaQuest experiment.

HEPAP meeting webcast

The winter meeting of the High Energy Physics Advisory Panel will take place on Monday and Tuesday in Washington, D.C. Both days of the meeting will be webcast. HEPAP advises the Federal Government on the national program in experimental and theoretical high-energy physics research.


Summer hiring changes

For this year's general summer hiring program, we are making a few changes to the process. The changes will not affect the intern programs. The changes are designed to democratize the program while preserving the preference given to employee-referred candidates – particularly the children of employees. The laboratory benefits from employing children of employees who know and respect laboratory culture, and employees benefit from their children's employment at a time when employment opportunities for youth are scarce.

The following changes will be made:

  • Ending the practice of name requesting candidates on personnel requisitions.
  • Stopping generic job postings. We will now post each job specified with individual duties and knowledge, skills and abilities (KSAs).
  • Evaluating candidates based on their responses to KSA based screening questions.
  • We will not consider candidates who do not submit responses to screening questions.
  • HR will refer only the top three candidates ranked for each job to the hiring manager.
  • If there are no employee-referred candidates available or if no employee-referred candidates meet the qualifications, then outside candidates will be considered.

These changes will be implemented on a pilot basis for 2012 with evaluation upon the conclusion of the summer hiring season. Employees are encouraged to provide feedback on their experience with the new process.

Hiring managers are encouraged to submit their Summer Personnel Requisitions as soon as possible, but no later than April 20 . The summer employment announcement will be posted on the Employment website upon receipt of an approved Summer Personnel Requisition form. The SPR form will be available here on Monday, March 12. Under the "Request Things" heading, click "Summer Personnel Request." Please contact Jason Johnson (x5810) with questions regarding the summer hiring program.

Daya Bay experiment makes key measurement, paves way for future discoveries

An international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade.

The results of the Daya Bay neutrino experiment open an important window into understanding the behavior of neutrinos, and now the race is on to determine the implications. Two American experiments, one proposed and one under construction, seem well positioned to take the next steps.

The problem of morphing

Whether or not they travel faster than light, neutrinos are perplexing particles. In the 1960s, scientists studying neutrinos produced in the sun discovered that a portion of them seemed to disappear as they made their way toward Earth.

Physics in a Nutshell

And so, ad infinitum: Smallest of the small

Scientists are searching for particles smaller than the familiar ones of the Standard Model.

Big fleas have little fleas, Upon their backs to bite 'em, And little fleas have lesser fleas, and so, ad infinitum. —Augustus De Morgan

Suppose you were the size of the universe - you would see a bunch of luminous, point-like dots surrounding you. If you shrank, you'd identify these points as galaxies, each with a rich structure and each filled with a new bunch of point-like dots. As you shrink more, you'd see that these new dots were not points, but stars.

If you pressed the supershrink button on your shrink ray, you'd zoom down through the size of humans, through cells, molecules, atoms, atomic nuclei, protons and neutrons and finally down to the size of the quarks and leptons that constitute the knowledge frontier of the super small. Over the past hundred years or so, a series of objects like atoms were thought to be the smallest building block of matter, only to have subsequent research show that we were wrong.

The Standard Model exemplifies the micro world of particle physics. Two classes of particles, called quarks and leptons, are thought to be the smallest building blocks of the universe. They have no size and contain nothing in them, but, if mixed correctly, they can build atoms, us, the entire universe.

After about a century of progressively finding something smaller than what we thought was the smallest, why should anyone think that these quarks and leptons are the final word? The answer is complex.

Daylight-saving - March 11

It's time to spring forward! Daylight-saving time begins this weekend. Don't forget to set your clocks ahead one hour Saturday night before going to bed. The shift to daylight-saving time also serves as a reminder to install new batteries in warning devices such as smoke detectors and hazard warning radios.
