Special Announcement

All-hands meeting Friday

An all-hands meeting will take place at 11 a.m. on Friday, June 19, in Ramsey Auditorium. Director Pier Oddone will discuss the focus group reports and how the laboratory plans to address the findings.

Employees can prepare for the meeting by reading and discussing the focus group reports.

Phishing for summer students

The laboratory is busy welcoming its new group of summer students. As these students are set up with computer accounts, we want to remind mentors and students to think about computer security practices.

Students, who are unfamiliar with how accounts are handled at the laboratory and don't know which messages are legitimate, can be fooled by phishing e-mails or fall prey to scams.

To prevent students from accidentally compromising machines, mentors should remind them of laboratory computer security practices, including:

  • Lock computer screens when you walk away from them
  • Never insert media from someone you don't know or trust (flash drive, cd) into your computer. Instead, direct them to the Servicedesk, located on the ground floor of Wilson Hall.
  • Don't click on links in e-mails if you can't verify the source.
  • Don't open attachments from sources you don't know or in e-mails that seem suspicious.
  • Never reveal your passwords to anyone at the laboratory for any reason: not to your supervisor, system manager or the computer security team. Never send passwords to anyone who asks for it via e-mail.

The message below was widely circulated at the laboratory by someone trying to trick people into giving up their account information and date of birth. This message is NOT legitimate:

Fermilab Result of the Week

A 'prime' analysis

The distribution of expected events for the number of jets for the b' signal and the relevant backgrounds. A b' signal would show up as an excess of events with a large jet multiplicity.

The Standard Model of particle physics contains three generations of quarks. Although these three generations explain a vast quantity of precise experimental data, there is no fundamental reason why a fourth generation of quarks should not exist. This week, we present the result of a search by CDF for a fourth-generation quark, which we call b' (b-prime).

If a fourth generation quark exists, it would be very massive and difficult to discover directly. For example, the Tevatron's discovery of the top quark 15 years ago took a large effort, mostly due to the particle's enormous mass, which is nearly equal to the mass of a gold atom, and its rare production even in high-energy collisions.

If it exists, the b' might decay to a top quark and a W boson. Physicists believe the particle would be produced in pairs and would have two top quarks and two W bosons as its signature. Physicists could clearly observe this signature. The decays of the top quarks and W bosons can produce two high-energy electrons or muons of the same electric charge. The signature would also have telltale signs, such as evidence of a bottom quark and an energy imbalance from unmeasured neutrinos.

This signature would be very rare from other processes. In five years' worth of analyzed data, CDF expected only two events from background processes. A fourth-generation quark would leave its mark with several more events.

When the data were analyzed, only two events satisfied the requirements, allowing CDF to rule out the existence of a b' particle if the particle's mass is less than 325 GeV, nearly twice the mass of the top quark.
