High School Teachers Collaborate on BTeV | ||
| ||
|
Three area high school physics and chemistry teachers are working with the
BTeV collaboration this summer through the Teachers Research Associates
Program at Fermilab, the lab's summer research program for secondary-school
teachers.
The teachers' summer research is funded by the outreach portion of the $5 million BTeV Real Time Embedded Systems grant from the National Science Foundation. The grant funds a collaboration of Fermilab computer scientists and physicists to develop BTeV's data acquisition and trigger systems. "We're all working on different parts of the RTES project," said Brenda Marr from Glenbard West High School. "Each year the RTES group sets up a mini computer farm to demonstrate where they are in the research. We're getting the next demo ready for this fall." Marr and Carolyn Degraff from Elgin High School are also working on a Web site to communicate the RTES project to students. "I came onboard knowing how to turn on a computer--that's about it," said Degraff. "I've already learned Linux and Flash, and now I'm learning Dreamweaver."
John Eggebrecht's work on software for BTeV will support part of his job at
the Illinois Math and Science Academy--maintaining the computer systems.
"This is nice, because I get to work on one problem all day long," said
Eggebrecht. "That's what really distinguishes it from teaching."

From U.S. Newswire, July 13, 2004 U.S. ITER Project Office will be Located at Princeton Plasma Physics Laboratory WASHINGTON, DC – The U.S. Department of Energy announced today that the U.S. project office for ITER, a major international fusion experiment, will be located at Princeton Plasma Physics Laboratory (PPPL). PPPL is located on Princeton University’s James Forrestal Campus in Plainsboro, NJ, and is charged with developing the scientific understanding and key innovations that will lead to an attractive fusion energy source. read more |

From Nature Magazine, July 15, 2004 Britain spends to secure scientific growth [LONDON] UK researchers will find more money in the coffers of those funding them over the next three years, thanks to spending plans announced by the government on 12 July.
The plans call for the country's two main science-funding streams,
which cater for basic research grants and university running costs,
to be boosted by 5.8% a year in real terms between 2004–05 and 2007–08.

A Tale of Two Lifetimes | ||
| ||
|
The study of elementary particles through their
disintegration could be described by updating an adage from
the early days of cosmic ray physics: One event determines
the mass, two events determine the lifetime and three events
determine the angular momentum properties.
Experimentalists at CDF have analyzed about 200 neutral Bs mesons (which consist of a strange and an anti-bottom quark) and their antiparticles in terms of their decays to J/psi phi. With this number of events, one can determine the angular momentum properties of the decays as a function of the particle's lifetime through the observed pattern of emission of the final state particles (2 muons and 2 charged kaons). The quantum oscillations occurring between the particle and anti-particle states of Bs mesons are so rapid, it is useful to consider the system in terms of Heavy and Light states. Each state decays with distinct angular distributions and different lifetimes. This analysis finds that about a quarter of the events are from the Heavy state and that this state lives about twice as long as the Light state. This implies that Bs mesons can readily be used to study matter-antimatter asymmetry. The sizeable lifetime difference may also present a challenge to the Standard Model. | ||
