Oddone Announces New ILC R&D Organization; Robert Kephart to Lead | ||
| ||
|
On Wednesday, August 10, Fermilab Director Pier Oddone announced a new organization for the Laboratory's International Linear Collider R&D Program.
"I believe these assignments will significantly strengthen our ILC R&D effort, which remains Fermilab's highest priority for the future," said Oddone.
"The International Linear Collider is a huge and exciting scientific initiative. I am humbled to be asked to join the Directorate and take responsibility for Fermilab's efforts on the ILC," said Kephart. "The ILC will make some great science possible; the superconducting technology is fascinating; and the international nature of this linear collider will be a challenge." Kephart, Nagaitsev and Mishra will form the core team that will coordinate Fermilab's ILC activities with the Global Design Effort, directed by Barry Barish.
"Let me offer my congratulations on the new organization and assignments for ILC R&D at Fermilab," said Barish. "This represents a very important step toward developing our ambitions for Fermilab to become a lead laboratory for ILC R&D. I very much look forward to working closely with this talented Fermilab team." |

ILC - Global Design Effort The Director's Corner
The Physics and Detector Workshop will be a regional American Linear Collider Physics Group (ALCPG) Workshop with expanded World Wide Study (WWS) participation. That workshop contains a set of panels: Physics Case panels; Two Complementary Detectors Panel; Software Tools Panel; Benchmarks Panel; Costing Panel; R&D Panel; Test Beam Panel; etc. Snowmass will represent a significant step forward in interactions between the WWS and ILC communities. Besides the large overlap for studies of the machine-detector interface, we hope to stimulate far more extensive interactions, including a set of lunchtime pedagogical talks on ILC-related accelerator physics.

nanoHUB Makes Nanotech Tools Easily Accessible By Katie Yurkewicz A nanometer is one-billionth of a meter—25,000 times smaller than the width of a human hair. At that tiny scale, matter can exhibit some strange, new behaviors. Nanotechnology researchers harness those behaviors to create new devices and materials, and the nanoHUB allows researchers and students to harness simulation tools, educational materials and computing resources necessary to study matter at the nanometer scale. |

From New Scientist, August 13, 2005 Heavyweights battle to expose the naked quark By Dana Mackenzie When a supercomputer took on a particle smasher in a race to pin down the ephemeral quark, the stakes could hardly have been higher. IT WAS a true clash of the titans. In the blue corner: a multimillion-dollar particle accelerator. In the red: one of the world's most powerful supercomputers. Both were battling to pin down the lifetime of an ephemeral subatomic particle known as the D-meson. Their deadline was 30 June. Two days ahead of their target, the 20 or so theorists behind the supercomputer announced their answer. For 48 nail-biting hours, they waited for their rival's result. They knew that if their numbers tallied, the supercomputer approach would have what it takes to revolutionise our understanding of the subatomic world. So when the 150-strong team at the accelerator finally announced that its answer matched, the theorists were over the moon. |

Seeking SUSY with beauty | ||
| ||
|
Particle physicists have been hunting for supersymmetry (SUSY) for decades. SUSY is a promising extension of the Standard Model (SM) which allows for the unification of all forces. Cosmologists are also excited about SUSY since it predicts a stable particle called the Lightest Supersymmetric Particle (LSP) which is a leading candidate for the dark matter in the cosmos.
For each existing Standard Model particle, SUSY predicts a yet-to-be-discovered more massive "superpartner." Unfortunately the theory does not predict the mass of these superpartners which makes it challenging for researchers to find them. At CDF, scientists for the first time have explored a specific hierarchy of the superpartner masses where the gluino (the superpartner of the gluon) is more massive than the sbottom (the superpartner of the bottom or beauty quark). This results in a truly "beautiful" experimental signature of 4 "b jets" or collimated sprays of energy from bottom quark decays, and a large imbalance of energy from 2 LSP's created from the supersymmetric particle decays. Since the bottom quark has a long lifetime, particles in the b jet will be displaced from the collision point by fractions of a millimeter, allowing b jets to be distinguished from jets produced by other types of quarks within the exquisitely precise CDF silicon detectors. After looking through millions of CDF events, the scientists have not yet observed a significant excess of these spectacular events above the SM background. This allows them to exclude a large region of possible sbottom and gluino masses as displayed by the purple line in the figure. The hunt for SUSY continues as the Tevatron experiments collect more data. | ||
