Boris Kayser Named Editor of Annual Review of Nuclear and Particle Science|
Fermilab scientist Boris Kayser, a theorist whose interests include neutrino physics and CP violation, has been named editor of the Annual Review of Nuclear and Particle Science. Kayser succeeds outgoing editor and Fermilab colleague Chris Quigg.
In 2001, after retiring from a 29-year career at the National Science Foundation, Kayser joined Fermilab's theoretical physics group. He enjoys activities that require him to know about a wide range of physics topics. As editor of the Annual Review, he will lead the editorial group that convenes each fall to identify topics ripe for review and the scientists who will write about them. Each volume covers a wide range of particle and nuclear physics topics: theory, experiment, technology and the reminiscences of a distinguished scientist.
"The articles should give people a clear introduction to a topic," explains Kayser. "I agree with Chris Quigg that the Annual Reviews should be the first place you'd send a student or someone new to a scientific field to learn about it."

- During this period of time Operations established two stores. These stores provided the experiments with approximately thirty-seven hours and 32 minutes of luminosity.
- The Fermi accelerators set two new luminosity records with both stores. The record is now 55.5E30.
- Switchyard experts successful in sending beam to the Switchyard dump.

Bush Administration Sends FY 2005 Budget to Congress
Characterizing the FY 2005 science and technology budget request that was sent to Congress on Monday is a classic example of a glass being viewed as half-full or half-empty. Although some components of the S&T budget request are up, others are down, or at least disappointing. Contrast the remarks made by OSTP Director John Marburger: "I think we have a good story here," with those of House Science Committee Chairman Sherwood Boehlert (R-NY) who said, "I am very disappointed in the proposed science budget . . . we just have to find a way to do better."
There are many different perspectives by which to view the S&T budget request. Faced with mounting deficits, the Bush Administration restrained future growth in discretionary program
spending. These are the programs for which funding can vary each year, such as for S&T, as compared to, for example, mandated expenditures for Social Security. Not counting discretionary
spending for defense and homeland security programs, discretionary programs account for less than one-fifth of the total federal budget. The Administration proposes to limit to just 0.5% the
overall increase for this portion of the budget.

World's science ministers call for open access to scientific data
Research ministers representing 34 countries, as well as the European Union, have adopted a declaration on access to research data from public funding aimed at enhancing the quality of science systems worldwide.
Further declarations on international scientific cooperation for sustainable development, neuroinformatics and high energy physics were also adopted at the same meeting of the Organisation for Economic Cooperation and Development (OECD) committee for scientific and technological policy on 29 and 30 January.
Ministers recognised that open access to data, information and knowledge 'contributes decisively to the advancement of scientific research and innovation' and 'maximise[s] the value derived from public investments in data collection'.
They therefore concluded that open and transparent methods for accessing research data should be created, either by strengthening existing instruments, or by establishing new mechanisms for collaboration. Achieving this aim whilst ensuring the protection of intellectual property and trade secrets was highlighted as a priority.
|CDF Searches for the Unknown in High-mass Dileptons|
As well as the Standard Model distills our understanding of particle physics, we know it can't describe the universe completely. Fortunately, the many theories seeking to go beyond the Standard Model fit into broader classes with many common elements. In general, they envision the Standard Model as a fragment of some bigger picture involving more particles and/or dimensions. In particular, they include new interactions among the highly energetic particles of the Tevatron beams.

Standard Model interactions predict the mass spectrum of quark and lepton pairs resulting from Tevatron collisions, so experimenters can search for new interactions by comparing this prediction with the observed spectrum. In some theories, the spectrum gradually diverges from the Standard Model prediction at high energies, while in others, Tevatron collisions produce new, heavy, neutral particles that decay into pairs of quarks or leptons similar to the much lighter Z-boson resonance.
|Koji Ikado began the current dielectron search at the start of Run II and will receive his Ph.D. in March from Japan's Waseda University. He also worked on the online monitoring at CDF.
This comparison is more certain for lepton pairs: the jet of particles associated with quarks muddies both predicted and observed spectra. This has motivated a group of CDF collaborators to search for these effects using electron and muon pairs. An improved silicon detector, more efficient data collection and better analysis techniques combine to capture more of these
interactions than in RunI, increasing sensitivity significantly. Run II results, still preliminary but nearing completion, explore many alternate theoretical predictions, including large extra dimensions, technicolor, R-parity violating SUSY, Randall-Sundrum gravitons, and the Z' that occur in E6 and Little Higgs models. While the data is currently consistent with the
Standard Model prediction, more Tevatron data may yet reveal surprises.
