Employees, Users and Contractors
Invited to Attend NuMI/MINOS Dedication on Friday|

Fermilab employees, users and contractors are invited to attend
the dedication ceremony for
the NuMI/MINOS experiment in Ramsey Auditorium at 2:30 p.m. on Friday, March 4.
Speaker of the House Dennis Hastert and DOE Office of Science Director Ray Orbach
will formally launch NuMI/MINOS.
A lab-wide party, sponsored by the URA,
will be held in the Atrium from 3:30 p.m. to 6:30 p.m., following the Auditorium
Portions of Ramsey Auditorium will be reserved for MINOS collaborators, NuMI
project staff, and special guests that include congressional staffers, DOE
officials, members of the press and other VIPs. Invitations have already been
sent via email to the people who will have reserved seats in the auditorium.
Ushers will be on hand to direct people to their seats. Overflow seating
will be available only after the auditorium is completely full.
All attendees should be seated in Ramsey Auditorium by 2:15 p.m. A slide
show on the history of the project, produced by Visual Media Services with the
assistance of Cat James,
will begin at that time. Employees are strongly encouraged to car-pool from
other areas of the site, as parking will be at a premium. The Horseshoe
will be completely reserved for participants in the ceremony. Additional
parking will be available at the Lederman Science Center.

Fermilab experiment to beam neutrinos through Dairyland
In an effort to pin down the elusive nature and qualities of one of nature's most intriguing subatomic particles - the neutrino - scientists at Fermi National Accelerator Laboratory, or Fermilab, in Illinois will soon send a beam of the ghostlike particles coursing through subterranean Wisconsin to a detector deep in a mine in northern Minnesota. The goal of the $170 million project is to help scientists gain some accurate measurements of a particle that has practically no heft.
Friday: Have Lunch with the Office of Science Director|
Dr. Raymond Orbach invites Fermilab and DOE employees to stop by
to talk with him during lunch in the cafeteria on Friday. Dr. Orbach
will help to dedicate the NuMI/MINOS project on Friday afternoon.
Muons Mark the Top Quark at CDF|
Observation of top-antitop production, appearing as an excess of events over
other known processes. The excess appears in events with one W boson and three
or more jets-- one of which contains a muon-- a characteristic signature of
top-antitop pairs. (Click on image for larger version.)|
Thirty five miles west of Chicago two detectors with the
cryptic names CDF and DZero attract hundreds of scientists
while recording the highest energy collisions on Earth. In
the heart of Chicago a building known as the John Hancock
Center attracts scores of tourists with its elegant
appearance. Both unique masterpieces, they have one
unmistakable difference: the skyscraper is massively bigger,
and much taller, than the detectors.
Mass is a familiar concept in everyday life, but oddly it is
one of the least understood properties in particle physics.
Matter in the universe appears to be made up of fundamental
building blocks called quarks and leptons, but the origin of
the masses of the building blocks remains a mystery.
Therefore the top quark, more than forty times heavier than
any other quark or lepton, could be playing a special yet
unknown role in physics. Highly unstable, top quarks decay
into one W boson (the particle carrier of the weak nuclear
force) and one b-quark. The b will bind with other quarks
leading to a jet of particles, and the identification of
these rapidly escaping b's is the key to detecting top quarks.
The CDF Collaboration now measures the production rate, or
cross section, of top-antitop pairs at the Tevatron by using
a technique that spots b's by looking for muons in jets. A
number of b's in fact will undergo a semileptonic decay, a
type of decay which often leads to the production of a muon.
Counting the number of events containing one W along with
muons in jets, in excess of those expected from background
sources, yields a determination of the top production
probability. The result, a cross section of 5.2+/-2.7 pb,
gives physicists at CDF yet one more tool to test the
properties of top quarks, the skyscrapers of all elementary
