Oddone: ILC Will Bring
the World to Fermilab

This article is the final piece of a three-part series on the EPP 2010 meeting at Fermilab.
In presenting the EPP 2010 panel with his vision for the future of Fermilab, Director-designate Pier Oddone offered guidance from a bumper sticker: "If you want to predict the future, help create it." Then he made his own intentions even clearer by quoting Daniel Burnham: "Make no little plans; they have no magic to stir men's blood," said Burnham, the famed architect

whose design of the 1893 Columbian Exposition transformed Chicago into a world city.

Oddone, who assumes the Director's office on July 1, picked up the theme: "When Burnham built the Columbian Exposition, the world came to Chicago. When we build the ILC, the world will come here."

To Oddone, a focus on leadership means results will follow. He described Fermilab as the world leader in neutrinos, in flavor physics, and at the high-energy frontier. Without new investment in a domestic accelerator program, he saw the lab falling to a secondary position by the next decade. "But with new and re-directed investment," Oddone said, "we would have a powerful new discovery machine at the energy frontier with the International Linear Collider, accompanied by a powerful neutrino program. Our goal is to have no question about the ILC by 2010, and to position the US and Fermilab to host the ILC."

Why Did the Turtle Cross
The Main Ring Road?

The answer: To lay its eggs. For the past several weeks, turtles at Fermilab have been crossing the Main Ring Road to lay their eggs near the berm. In the process of crossing the road, several of the turtles have been killed by cars, bicyclists and pedestrians.

The turtles nest from late May to mid July and lay anywhere from two to twenty eggs. The hatchlings look like small round flat stones. When their shells are dry, they blend into the road very easily. When the shells are wet, they are black. Employees and users are asked to watch out for these small hatchlings and avoid running them over. If the stone has feet and a tail, it is a turtle, and it deserves a fair chance.

More information about turtles at Fermilab is available online.

Accelerator Update
May 16 - May 18
- During this 48 hour period Operations established one store that combined with an existing store provided the experiments with approximately 30 hours and 27 minutes of luminosity
- Booster suffered from RF, EAPS, and Chopper problems
- NuMI sent beam during Recycler shot setup
- TeV quenched after store 4148 terminated

Quantum Black Holes
Physicists could soon be creating black holes in the laboratory
By Bernard J. Carr and Steven B. Giddings
Ever since physicists invented particle accelerators, nearly 80 years ago, they have used them for such exotic tasks as splitting atoms, transmuting elements, producing antimatter and creating particles not previously observed in nature. With luck, though, they could soon undertake a challenge that will make those achievements seem almost pedestrian. Accelerators may produce the most profoundly mysterious objects in the universe: black holes.

Tautally Top
An event display showing one of the two candidate top+anti-top -> tau+electron+neutrinos+jets events. The neutrinos are inferred from the imbalance in momentum transverse to the beam. One jet has a displaced vertex in the silicon micro-vertex detector, consistent with a b-quark. (Click on image for larger version.)
The Standard Model of particle physics organizes the fundamental particles and describes the laws that govern the interactions of the particles through three of the four fundamental forces. Quarks and leptons are organized into three generations, with only the first generation present in the familiar particles of matter: protons, neutrons, and electrons. A recent analysis of Run II CDF data explores a decay chain that consists of entirely third generation quarks and leptons, searching for top quarks that decay to tau leptons through the decay of W bosons.

Top quarks are produced in approximately one in every ten billion collisions at the Tevatron, and are very challenging to detect. The easiest top signature requires at least one energetic lepton amongst the decay products. Here we search for events with two leptons: one electron or muon, and one tau. Finding tau leptons is particularly difficult, and finding top is already akin to searching for a needle in a haystack...why go through so much work?

The high masses of the third generation particles mean that the couplings of these particles to the elusive Higgs boson are strong. Models of Supersymmetry predict the possibility of a charged Higgs boson which could be produced in top decay, and might preferentially decay to taus. This first measurement in Run II finds two candidate events with one background event predicted. It is consistent with no enhanced rate due to Supersymmetry, but only excludes the most extreme possible rate enhancements. With the full dataset expected in Run II however, this search will eventually either discover — or place stringent limits on — the possibility of this enhanced third generation decay of the top quark.
