Top Promotions for Six Scientists On June 14, Fermilab Director Mike Witherell announced the promotion of six Fermilab scientists to the highest job category attainable by scientific personnel at the lab: Arlene Lennox was promoted to Applied Scientist III, and Roger Dixon, Joe Lykken, Paul Mantsch, Jim Strait as well as John Womersley were promoted to Scientist III. Their job promotion citations highlight the "substantial and sustained scientific contributions" these scientists have made to Fermilab, and how they have demonstrated "considerable and unusual leadership ability pertaining to the scientific or technical achievements of the laboratory," two of the criteria used in promotions to level III. Fermilab Today congratulates. Read more |

In Concert: Cascada de Flores | ||
| ||
|
The Fermilab Arts Series presents Cascada de Flores on June 25, at 8 p.m. The four musicians of Cascada de Flores ("waterfall of flowers") present Mexican and Cuban music and dance, combining the sounds and styles of older popular and traditional music with a plethora of instruments: guitars, tres cubano, "guitarjón" (a baritone guitar made out of a cajón by Jorge Mijangos), flute, marimbol (a bass lamellaphone related to the African thumb piano), requinto and jaranas of Veracruz, donkey's jaw bone, feet, and cajón.
Tickets for Cascada de Flores are $18 ($9 for ages 18 and under). For further information or phone reservations, call 630-840-2787 weekdays between 9 a.m. and 4 p.m.

Computer Security Vulnerability in MSSQL A common software package installed with many popular Microsoft Windows based products is the database program MSSQL/MSDE (Microsoft SQL Server or Microsoft SQL Server Desktop Edition). It is often installed as part of another software package without the user's knowledge. Examples of software which may install MSSQL are Visio, FoxPro, Visual Studio, OfficeXP, Backup Exec, Compac's Insight Manager, and McAffee products, among many others. Many computer security incidents at the lab have been associated with exploits of this package. Two steps are being taken to reduce the lab's vulnerability. First, beginning on June 30, 2005, MSSQL services cannot be offered offsite unless the system administrator has implemented host restrictions to only allow access by specific Internet hosts. Note that onsite access is not affected by this change and continues to be permitted. Second, scanning has started for blank and weak passwords on MSSQL accounts. In one recent computer security incident, a machine was compromised because a user had chosen the password "sa" for the sa account. Please choose strong passwords for all accounts. Systems which are detected by the scanner as failing to meet either of these new requirements will be blocked from the network until the configuration has been corrected.
PC managers and General Computer Security Coordinators have discussed these topics in several forums, and they will be able to help you if you have further questions. Additional technical details on this topic are available online.

From PhysOrg.com, June 15, 2005 Ripples In Cosmic Neutrino Background Measured For The First Time Astrophysicists from the Universities of Oxford and Rome have for the first time found evidence of ripples in the Universe's primordial sea of neutrinos, confirming the predictions of both Big Bang theory and the Standard Model of particle physics.
The discovery, made by combining data produced by the NASA WMAP (Wilkinson Microwave Anisotropy Probe) satellite and the Sloan Digital Sky Survey, confirms the predictions of both the Big Bang theory and the Standard Model of particle physics. The research has important implications for the study of neutrinos, showing that theories of the infinitely large (cosmology) and the infinitely small (particle physics) are in agreement. |

Top Quarks are a Higgs' Best Friend | ||
| ||
|
One of the most sought-after particles in high energy physics, the Higgs boson, has
a key characteristic: it likes to be produced by (or decay into) particles with
large mass. This is good news for physicists using the Tevatron for experiments, because they have access to the most massive particle known to exist--the top quark!
CDF scientists have recently combed over their sample of top quarks and carefully studied the "final state" particles observed in their detector when the tops decayed. The Standard Model (SM) makes precise predictions about the relative amounts of different particles one expects to observe in a sample of tops. The mix of these particles can be quite different from the SM, if top quarks sometimes decay into charged Higgs bosons (whose existence is predicted by supersymmetric, or SUSY, extensions of the SM). The CDF study shows that so far the top quark books are balanced; the different final states are present in the amounts predicted by the Standard Model. This yields information about the properties of a charged Higgs boson: either its mass is too heavy for a top quark to decay into it with any appreciable rate, or another quantity (such as the parameter "tan beta" in popular SUSY models) is conspiring to suppress its production. The above figure shows values of tan beta and Higgs mass that can be ruled out from the CDF data. But note the white region that is still "up for grabs:" this is where the charged Higgs may be lurking, awaiting discovery. | ||
