Special Announcement

HEPAP meeting will not be available via webcast

The winter meeting of the High Energy Physics Advisory Panel will take place today and tomorrow in Washington, D.C. Contrary to initial plans, the meeting will not be available for viewing online.

HEPAP advises the Federal Government on the national program in experimental and theoretical high-energy physics research.

Scientists continue to see puzzling behavior in top quarks, reaffirm strength of Tevatron experiments

The Collider Detector at Fermilab (CDF).

The Tevatron may be shut down for good, but – as evidenced by the catalogue of results presented at this week's Rencontres de Moriond conference – the collider's experiments still have plenty to say.

In some areas, the Fermilab experiments still hold the advantage over those at the higher-powered Large Hadron Collider at CERN.

Fermilab's CDF experiment announced today that physicists continue to see possible signs of new physics in their ongoing study of the heaviest type of quarks, top quarks. Last year, scientists at CDF and its sister experiment, DZero, detected a difference between the ways top quarks and their antiparticles behaved when springing from collisions at the Tevatron. Top quarks preferred to propel in the forward direction, and anti-top quarks preferred the opposite. The level of asymmetry they found went against current predictions from the Standard Model of particle physics.

"It forces people to rethink this kind of physics and the way these predictions are made," said Giovanni Punzi, co-spokesperson of the CDF experiment.

After about doubling the dataset they were using, CDF scientists repeated the study. The results held fast. The asymmetry in question measured at 0.296 ± 0.067 percent, when theory predicted it should fall at 0.100.

Strange effects: The mystifying history of neutrino experiments

From Wired Science, March 9, 2012

Late last year, scientists with the OPERA collaboration in Gran Sasso, Italy reported an incredible finding: neutrinos that appeared to be moving faster than the speed of light.

The news spread at a barely slower pace, fascinating the public. One thing everyone knows is that a very famous physicist named Albert Einstein once said that nothing should travel faster than light speed.

In February, the OPERA researchers found a couple small problems with their experimental set-up, calling into question the original faster-than-light neutrino result. The event highlighted the difficulty of science at the edge of the unknown -- and neutrinos are especially tricky.

More often than not, neutrino experiments throughout history have turned up perplexing results.

Scientists getting clearer picture of 'God particle'

From, March 7, 2012

This could be the year of the Higgs boson, the most sought-after particle in all of physics. More clues about it are emerging at a U.S.-based collider whose budgetary woes shut it down last year.

The Department of Energy's Fermi National Accelerator Laboratory (Fermilab) has just announced that it has found hints of the ever-so-important particle, which are consistent with observations from the Large Hadron Collider.

Finding the Higgs boson would help explain the origin of mass, one of the open questions in physicists' current understanding of the way the universe works. The particle has been so difficult to pin down (metaphorically speaking) that physicist Leon Lederman reportedly wanted to call his book "The Goddamn Particle." But he truncated that epithet to "The God Particle," which may have helped elevate the particle's allure in popular culture.

ES&H Tip of the Week:
Computer Security

Spring into cyber safety

Computer security breaches can be prevented with proper vigilence.

Spring is just around the corner. It brings warm weather, with Fermilab employees shedding their winter wear after months of cold. While you recover from the chill, there's a fresh batch of things to think about, from seasonal allergies to sunscreen. Even though the season changes, you still need to protect yourself and those around. This should extend to your computer, as well.

Your computer probably has old software no longer needed or sorely out of date and in need of freshening up. Leaving software installed that is no longer needed, or not keeping it updated to the latest versions, clutters up your hard drive. It also makes it extremely easy for attackers to compromise your computer. A simple email containing a malicious attachment can take advantage of old software to control your computer. Every day, your email is bombarded with fake emails with attachments posing as pictures, documents or movies, all of which are carefully designed attempts to exploit holes in your software.

We are constantly under attack. In the last week alone, we have received six new alerts from DOE about new security vulnerabilities and ongoing attempts to exploit these vulnerabilities. Also in the last week, another DOE laboratory suffered penetration of its cyber infrastructure by malicious outsiders. Our chain of defense is only as strong as the weakest link, which can be any single user on site running vulnerable software. One such example is Fermi Scientific Linux version 4, for which the vendor no longer distributes security patches.

To aid the defense, take care when opening emails and attachments. Keep your antivirus software running and updated. Be sure to routinely apply patches to your computer by enabling automatic updates or by visiting your operating system and software vendors' websites. Be particularly careful of third party software (Flash and other Adobe products, for example), which are often not automatically updated.

A lot of software has a menu option to check for updates, which makes the process easier. If you are unsure if you are running latest software versions, ask you system administrator to check. You can find out who that is by going to the Computing Sector website and clicking "Verify your node registration."
