Renowned Lyric Opera Stars
Perform Wednesday, Feb. 8

Basso-Baritone Andrea Silvestrelli has performed at the most important opera houses in the world, including Teatro alla Scala in Milan, the Sydney Opera House and the Lyric Opera of Chicago. (Click on image for larger version.)
The Cultural Association of Italians at Fermilab, along with the Instituto Italiano di Cultura di Chicago is proud to present one of the stars of Lyric Opera, Basso-Baritone Andrea Silvestrelli, along with Soprano Teresa Cullen, and accompanied by Eric Weimer on piano. The recital, which includes works by Mahler, Ravel, Tosti, and others, will take

place in Ramsey Auditorium on Wednesday, Feb. 8, beginning at 8 p.m.

Silvestrelli, an internationally celebrated bass-baritone, made his debut in 1989 at Jesi (Ancona) in Macbeth and soon thereafter appeared in Don Giovanni at the Teatro Comunale, Bologna, and the Teatro dell'Opera, Rome. Since then, he has sung at the most important opera houses in the world, including La Scala (Milan), the Bastille (Paris), Covent Garden (London), the Concertgebouw (Amsterdam), Sydney Opera House, and the Lyric Opera of Chicago, working with conductors such as Muti, Mehta, Abbado, Kuhn, Bychkov, and Chung. In last year's season at the Lyric Opera of Chicago, he interpreted the role of the Commendatore in Don Giovanni.

Cullen made her European debut at Teatro alla Scala (Milan) singing Marina in Luciano Berio's world premiere Outis. While a member of the Lyric Opera Center for American Artists, Cullen performed the title roles in Carmen, L'heure Espagnole, and Cosi fan Tutte. Main season productions included roles in La Traviata, Das Rheingold, and Die Walkure.

Tickets for Andrea Silvestrelli & Teresa Cullen in Recital are $15. For further information or telephone reservations, call 630/840-ARTS (2787) weekdays between 9 a.m. and 4 p.m.

Science Grid This Week
From Pakistan to Pasadena

Over the past 18 months, five students from the National University of Sciences and Technology in Pakistan have traveled to Caltech to develop their grid computing skills. The students, who have already collaborated remotely with Caltech scientists for at least one year, spend six months in California developing grid software and services.

"It's a fantastic learning experience," says Adeel Zafar, one of two NUST students currently visiting Caltech. Zafar and Atif Mehmood, both research assistants preparing to apply to graduate school, started working on grids at NUST in early 2004. They deployed a grid node for the CMS particle physics experiment, then moved to developing Web services for the Grid Analysis Environment.

In the News
From White House Press Briefing, February 1, 2006:
Press Briefing by Administration Officials on American Competitiveness Initiative

Remarks by Secretary of Energy Samuel Bodman: "You already heard about ...the importance of last night's remarks by the President. I would like to take this opportunity to discuss the role that the Department of Energy will play in this competitiveness initiative.

"To maintain our country's competitive edge we simply have to generate not just new technologies, but transformational technologies -- technologies that change the very nature of products. And that -- it's that act that will continue to provide for the dominance of our economic activities, for our science and for our technologists. Out of that will come the development of alternative sources of energy that, in fact, will lead to the decrease of our dependence on foreign sources of energy. And that is why the President has committed himself to doubling the federal spending in the combined offices of the National Science Foundation, the NIST activity in the Department of Commerce that you just heard about, and the Office of Science in the Department of Energy. That doubling will occur over the next 10 years. ..."

Neutrinos and the Light Higgs Boson at DZero
The mass distribution for Higgs candidate events. (Click on images for larger version.)
We know how heavy the top quark and the weak force-carrying W and Z bosons are, but we don't know how they get so much heavier than a proton. The Standard Model of particle physics, which describes all current experimental results, predicts that the mass of the fundamental particles--quarks, leptons, and W, Z bosons--are given by a new particle, the Higgs boson. Although the Standard Model cannot predict the exact mass of the Higgs boson, many experimental results tell us that it should be light, probably in the mass range between 100 to 140 GeV/c2, where the Tevatron has the capability of producing it.

DZero has been searching for the Higgs boson using several production channels. The search presented here looks for simultaneous production of a Higgs boson and a Z boson (the so-called associated Z-Higgs production). The Z may subsequently decay into a neutrino pair and the Higgs boson into a b-quark pair. This is one of the most sensitive decay channels for the Higgs boson search at Tevatron if the mass is smaller than about 140 GeV/c2. The neutrinos pass undetected through the DZero detector and the resulting "missing energy" can signal the presence of associated Z-Higgs production. The b-quarks are detected as jets of particles with a "secondary vertex" well away from the primary proton-antiproton collision point. The graphic above shows the mass of the b-quark jets for events with large missing energy. A Higgs boson would show up as a bump in the data, which is not seen. Using this information we can set a limit on the production of the Higgs at the Tevatron. The limit is consistent with the Standard Model.

As the Tevatron continues to deliver luminosity, and if nature is friendly to us, we may well uncover the Higgs.

Women and Heart Disease
Wellness Works presents Women and Heart Disease Brown Bag Seminar February 8 at noon in WH1 West. The seminar will be presented by Dr. Santosh Gill, MD, Medical Director for the Women's Heart Center and Cardiology at Rush-Copely Medical Center. Join us to increase your awareness of the risks and effects of Heart Disease, the number one killer of American women. The first 25 women at the seminar will receive the Red Dress Pin, which is the national symbol for women and heart disease. Note: The National Heart, Lung, and Blood Institute is also promoting awareness by asking women to wear red on February 3.
