LHC Physics Center Celebrates New Floor | ||
| ||
|
Although aerial photos of the LHC, cross-section diagrams of the CMS and a Swiss
espresso machine might seem to distinctively characterize the environment
at CERN, you could also just as well be on the 11th floor here at Wilson Hall.
Tuesday's Open House held by Fermilab's new LHC Physics Center (LPC)
celebrated the construction of a physical place at Fermilab where US
physicists can contribute to the world's soon-to-be largest particle accelerator,
despite a distance of several thousand miles.
"The conceptual plan of the LPC has been here for years," said Kaori Maeshima of Fermilab's Particle Physics Division and CMS department. "But only since last spring have we started the actual construction and knocking down the walls, and it was just finished in December." Dan Green of Fermilab's Particle Physics Division and CMS department said that the floorplan is intended to maximize user collaboration. "This is a customer-based operation. We have a few things that aren't on your typical floor, such as a help desk to direct people to experts of different sub-systems. There are large, open spaces where people can easily communicate, three teleconferencing rooms and a remote operations center." Fermilab employees will use the 11th floor along with researchers, post-docs and grad students from 40 universities. "We are going into a completely new area in physics," said Hans Wenzel of Fermilab's Computing Division and CMS department. "There is strong potential for major discoveries. Feedback and discussing new ideas will be very important, and in some ways, people here can participate much more actively than if they were at the site."
"This place will be here for decades to come," said Fermilab Director Mike
Witherell. "It's the start of something big."

From the Chicago Sun-Times, January 4, 2004 Isotope lab would be big win for state Illinois has a unique opportunity to raise its visibility as a world-class technology leader. In 2005 the U.S. Department of Energy will select a research organization to build, manage and operate a $1 billion Rare Isotope Accelerator facility. Argonne National Laboratory, in conjunction with the University of Chicago and with the support of the Illinois Department of Commerce and Economic Opportunity, is a top contender to win the project. read more

More Symmetry in Charm | ||
| ||
|
The Collider Detector at Fermilab in Run II has often
been dubbed the Charm Detector Facility due to its
capability of recording huge samples of charm mesons,
identified by their signature of a decay vertex displaced
from the beam axis.
Presently CDF has more than
A team of CDF researchers from Italy and the U.S. has
studied the decay chain The Standard Model predicts CP asymmetries well below the 1% level in these decay rates, but it is easy to conceive of alternative models that could produce more sizeable effects. Using data from the first year of Run II, corresponding to 120 pb-1, very clean charm samples were selected. Careful analysis has allowed CDF to put the most stringent limits to date on direct CP asymmetries: ACP(K+K-)=2.0+/-1.2(stat)+/-0.6(sys)%, and ACP(pi+pi-)=1.0+/-1.3(stat)+/-0.6(sys)%, both consistent with no CP asymmetry. After the recent discovery of CP violation in B0-->K+pi- decay rates and the very well known effects in K0 decays, this result confirm that charm mesons might be the only heavy flavor mesons that do not exhibit violations of this fundamental symmetry. | ||
