Dorm Two Receives Updated Look

|
On January 1 of this year, residents of Dorm Two were
temporarily relocated to clear the way for the building's
first renovations in many years. Several outside contractors
and a few Fermilab employees carried out the renovations,
which were completed in mid-February. Dorm Two now boasts
new floors and carpeting, freshly painted interior walls,
new and renovated bathrooms and a new laundry center.
Furniture in the common areas was changed, and last year
the dorm was equipped with wireless Internet access.
"The residents really like the fresh look. They have given
us very positive feedback," said the Housing Office's Linda Olson-Roach.
Dorm Two, originally five separate houses joined together to
serve as offices, has 19 rooms and can hold up to 26 residents.
Fermilab's seven dorms provide temporary and long-term housing
for up to 115 laboratory users and employees with term appointments.

Partners fail to find common ground for fusion project
by Declan Butler
[PARIS] Iter means 'the way' in Latin — but 'lost its way' might be a more apt description of the international fusion project that bears the name.
A technical assessment intended to break a stalemate over where to site the facility has itself ended in deadlock, with the six partners blaming each other for the lack of progress.
Negotiations over ITER's site have been stalled since a ministerial meeting in Washington last December, when the United States and South Korea backed the Japanese site at Rokkasho, and China and Russia supported the European Union's site at Cadarache in France. The US$5-billion project seeks to show that heating plasma in a magnetic field can produce fusion energy.

DZero: Looking for New Physics With Photons
|
|
A three-dimensional representation of a DZero event with two photons (red
arrows), an electron (purple arrow), and a significant misbalance of transverse
energy (blue arrow). Large missing transverse energy is typically associated
with production of neutrinos but could also signal the presence of particles
responsible for cosmological dark matter. (Click on image for larger version.) |

Today, more than thirty years after Supersymmetry was proposed,
it remains one of the most attractive ways of extending the
Standard Model and unifying the forces. It predicts that each known fermion has a boson superpartner; and each known boson, a fermion superpartner.
In fact, these superparticles could be
the dark matter that pervades the universe. Supersymmetry
has not yet been observed and there are a variety of models
that attempt to explain why this is so. One class of
models predicts events with two isolated photons and large
missing energy that could be observed at the Tevatron.

In Run II, the DZero collaboration is continuing the search for such
events. The event in the figure has two photons with transverse
energy of 69 and 27 GeV, an electron of 24 GeV and missing
transverse energy of 63 GeV. While an interesting event,
the collaboration must first understand what background
processes could give rise to such an event.
This could be an event with a W boson and two jets where
the jets are misidentified as photons. The analysis team is now
carefully estimating all Standard Model sources of background
and is on the lookout for more unusual events in the growing
data sample.
Using data acquired prior to the event pictured, the
collaboration has set the best current limits on such processes.
These models predict new particles called gauginos and DZero can say
that if a charged gaugino exists, it must be at least
180 times more massive than a proton. Limits such
as this give important constraints on our understanding of
the universe.

Women's Personal Protection & Self Defense Class
Due to its tremendous success, the Recreation Office will
be offering another Women's Personal Protection & Self
Defense Class. The next 6-week class will be from April 7 -
May 12. Classes are held on Wednesday evenings from 5:30-7:30 PM.
Classes are held at the Kuhn Barn in the village. The cost for
this class is $35.00 and is open to all Fermilab women,
their mothers and daughters.
Registration deadline is April 2. No Recreation membership is
needed.
