Calendar Special Announcement Fermilab Result of the Week

Thursday, Feb. 26 First Extreme Beam lecture Seeing jets from the top THERE WILL BE NO today, 4 p.m. in One West PHYSICS AND DETECTOR SEMINAR THIS WEEK 2:30 p.m. Theoretical Physics Seminar - Curia II Speaker: Johan Alwall, SLAC National Accelerator Laboratory Title: QCD Radiation and New Physics Production at the LHC 3:30 p.m. DIRECTOR'S COFFEE BREAK - 2nd Flr X-Over THERE WILL BE NO The first lecture in the Extreme Beam lecture ACCELERATOR PHYSICS series will take place today at Fermilab. AND TECHNOLOGY SEMINAR TODAY The first lecture of the Extreme Beam lecture series will take place at 4 p.m. today in One Distribution of the reconstructed top quark mass 4 p.m. for signal events with at least two b-quark jets. Extreme Beam: Physics at the West. Junji Hisano, from the University of Tokyo’s Institute for Cosmic Ray Research, Intensity Frontier Lecture Even 14 years after its discovery, the top will give a talk titled “Charged Lepton Flavor Series - One West quark is largely terra incognita. Its heavy mass Violation.” Speaker: Junji Hisano, was the most surprising property at the time of University of Tokyo The lecture series, which will feature talks at its discovery, and is still a captivating topic. Title: Charged Lepton Flavor Fermilab throughout 2009, will give in-depth Nowadays, the precise knowledge of the top Violation information about the science and accelerator quark mass can be used to constrain the mass and detector technologies that will create a of another theorized special particle, the Higgs Friday, Feb. 27 world-leading physics program at the Intensity boson, but also it suggests a special role of 3:30 p.m. Frontier. the top quark in the particle family. DIRECTOR'S COFFEE BREAK - 2nd Flr X-Over Visit the Extreme Beam Web site for more Most of the Tevatron collisions produce quarks 4 p.m. or gluons, which appear in the detector as information. Joint Experimental-Theoretical sprays of particles called jets. Top quarks on Physics Seminar - One West Feature the other hand are produced only once in 10 Speaker: Mayly Sanchez, billion collisions. They appear mostly in pairs, Argonne National Laboratory AAAS and AAPT talks now each decaying very quickly to a b quark and a Title: Initial Study of nm -> ne W boson. B quarks produce long-lived Transitions in MINOS available online particles whose decay products can be 8 p.m. This month, the American Association for the identified, allowing b jets to be “tagged.” W Fermilab Lecture Series - Advancement of Science hosted in Chicago bosons can decay into leptons, which are uncommon at a hadron collider such as the Auditorium one of the largest and most diverse science Tevatron. This helps to improve purity by Tickets: $5 meetings in the United States. The conference removing background events that do not Speaker: Dr. Angela Olinto, coincided with the winter meeting of the contain leptons. University of Chicago American Association of Physics Teachers. Title: Chasing Cosmic Bullets: Still, the W bosons usually decay into two The Pierre Auger Observatory More than 40 scientists and teachers gave talks on particle physics, astrophysics and quarks each; giving four jets in addition to the ones from b quarks. A CDF group used this Click here for NALCAL, cosmology. A Fermilab Web site now offers signature, only based on jets, to isolate a a weekly calendar with pdf and PowerPoint files of most of these presentations. Highlights include a session on sample of top quark events. After requiring b- links to additional tagged jets, they further cleaned up the event physics at the intensity frontier, research with information. sample by exploiting the differences between the Tevatron collider experiments; and particle Weather the jets that originated from quarks and the physics experiments for high school students. jets that originated from gluons.

people who are interested in particle physics. Using this novel approach, CDF scientists Heavy rain achieved the highest purity ever obtained in 47°/25° this sample, and they were able to measure Extended Forecast the top mass with the unprecedented precision Photo of the Day for this channel of 1.5 percent. Weather at Fermilab Current Security Delegation from Hungary visits This measurement will help increase the Status Fermilab overall precision on the knowledge of the top quark mass. Also, with a sample much cleaner Secon Level 3 than in the past, many additional studies using Wilson Hall Cafe top quarks are now possible, and scientists hope to be surprised by the outcomes.
