Press Release: Fermilab Experiment Prepares to Send Its First Neutrinos to Minnesota | ||
| ||
|
Scientists at Fermilab will begin a projected five-year experiment in early February, 2005 by sending the first batches of subatomic particles called neutrinos on a path through the earth from the laboratory, about 40 miles west of Chicago, to a detector located in the historic Soudan iron mine a half-mile underground in the northeastern corner of Minnesota, about 450 miles away.
Neutrinos are extremely abundant in nature - trillions of them are passing through us at any given moment. They interact with the atoms of ordinary matter so seldom that they can pass through air, water, rocks, or people without a trace. Neutrinos from cosmic rays go through the entire Earth, mysteriously morphing from one kind to another as they travel through space.

Fermilab Art Gallery Hosts Artist Reception for
Chicago Tribune
Photojournalist Pete Souza | ||
| ||
|
On January 28, the Fermilab Art Gallery will host an Artist Reception for
Pete Souza, a Chicago Tribune photojournalist, from 5:00 p.m. to 7:00 p.m.
on the second floor crossover. Originally published as a 12-page, all-color
section in the Tribune in December 2003, the exhibit, "Environmental Battlegrounds," is a collection of photographs that focuses on the Bush administration's impact on the environment.
For the majority of 2003, Souza traveled everywhere from Alaska to just outside Chicago to capture the perfect images for his project. "I wanted to give readers a sense of what these places are like," Souza said. "I also tried to come up with environmental issues that would be in the news for a while."
As a photojournalist for the Chicago Tribune's Washington D.C. bureau, "Environmental Battlegrounds" is a departure from Souza's usual political photographs. Souza was also an Official White House Photographer for President Ronald Reagan from 1983 to 1989. When the former president passed away in 2004, Nancy Reagan personally asked Souza to photograph the funeral. "It was a very historic week," he said. "For me it was the final chapter for coverage of Reagan." "Environmental Battlegrounds" will be on display in Fermilab's Art Gallery until April 1, 2005. Souza will also give a lecture about his exhibit immediately following the Artist Reception at 7:00 p.m. in One West. "I like doing projects like 'Environmental Battlegrounds' because it gets me out of the political scene for a little while," Souza said. "I'm very excited about this exhibit because not everyone saw it in the Tribune, and this is another chance for people to see the images." |

From the Stanford Report, January 26, 2005 SLAC�s SPEAR3 accelerator restarts after safety probes By Neil Calder The Stanford Synchrotron Radiation Laboratory's SPEAR3 facility completed its restart validation process last week, and Stanford Linear Accelerator Center (SLAC) Director Jonathan Dorfan, after consultation with the Department of Energy (DOE), gave the green light to restart operations. Dorfan had ordered the immediate suspension of operations of SPEAR3 and SLAC's principal high energy physics facility, the B Factory, after a serious electrical accident on Oct. 11, 2004. read more |

Boson May Illuminate New Physics | ||
| ||
|
Z bosons and photons are carriers of two of the four fundamental forces of
nature. Theory predicts that while the two may be produced together in a
proton-antiproton collision, the Z boson and the photon do not directly
interact with each other. Thus if an excess of Z+photon events is observed,
it could be a sign of unexpected properties of the
Z boson. Measurements of the Z+photon production cross section, and
limits on the Z+photon couplings were made in Run I, by both the DZero and
CDF Collaborations.
The much larger Run II data sample yields ten times as many Z+photon candidate events as found in Run I. DZero detects the Z+gamma events in final states where the Z boson decays into a pair of electrons or muons. DZero observes 290 candidate events, with a background expectation of 46 events, in 0.3fb-1 of data. The data were searched for events containing a high energy photon, which might signal new physics. Observations are in good agreement with Standard Model theory predictions (as shown in the figure). Using the spectrum of the photons, limits were set on the coupling of the photon to the Z boson. | ||
