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
Pier Oddone at the|
EPP 2010 meeting.
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?

Fermilab. (Photo: Greg Vogel)(Click on image for larger version.)|
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.

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.
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
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.

Third Thursday Lunchtime Cleanup Today|
The Thursday Lunchtime Cleanup will be on
May 19 from 11:45 a.m. to 1:30 p.m. Transportation to the clean-up
site will be available outside the east ground floor entrance of
Wilson Hall. Cleaning gear will be provided, and hot dogs and
refreshments will be served. Call Bob Lootens at x3303 for
Work in Wilson Hall
Starting tomorrow, FESS will bring equipment into Wilson Hall
to conduct repairs on the south window wall under the thirteenth
