Special Announcement

Physics for Everyone - today in Ramsey Auditorium

Today from 12:30 to 1:30 p.m. in Ramsey Auditorium, Fermilab physicist Don Lincoln will give a talk titled, "Relativity at the Energy Frontier." The talk will include time for questions and answers.

"Physics for Everyone" is a non-technical lecture series about Fermilab science and culture. Information on upcoming lectures and video of previous lectures is available on the series website. This lecture series is organized by the Diversity Council Subcommittee for Non-Scientific and Non-Technical Employees.

State-of-the-laboratory meeting for scientists - today

Fermilab Director Pier Oddone and Deputy Director Young-Kee Kim will host a state-of-the-laboratory meeting for scientists today from 2:30 p.m. to 4 p.m. in One West. All scientists are encouraged to attend.

Additional state-of-the-laboratory meetings for other employee groups will take place tomorrow.

SLAC gets a new director

Yesterday Stanford University announced that Chi-Chang Kao will serve as SLAC's fifth director.

SLAC has a new director: X-ray scientist Chi-Chang Kao. Kao currently serves as Associate Laboratory Director for SLAC's Stanford Synchrotron Radiation Lightsource and Acting Associate Laboratory Director for the lab's Photon Science directorate. He will assume the directorship on Nov. 1.

Kao will succeed Persis Drell, who announced late last year that she would step down this fall to return to particle physics research and teaching.

"A committee conducted an international search to find SLAC's next director for nearly 10 months and considered dozens of candidates before making recommendations," Stanford University President John Hennessy said in a statement released by Stanford, which operates the laboratory for the U.S. Department of Energy. "In the end, it was clear to us that the best candidate for the job was clearly the one already at SLAC. Chi-Chang is both a respected scientist in X-ray science known globally for his accomplishments and a proven leader, someone who can energetically lead the laboratory's excellent faculty and staff and chart a bold course for SLAC's scientific direction in the coming years."

Secretary of Energy Steven Chu concurred, saying "Chi-Chang is an excellent choice to lead SLAC at this exciting time in its history. He is an outstanding scientist, and he has earned the respect of all those he has worked with at the DOE. SLAC has seen great success in the last few years with the Linac Coherent Light Source, the world's most powerful X-ray laser. With his experience and expertise in X-ray science, Chi-Chang is the right person to set a vision for how this extraordinary machine, as well as SLAC's other excellent facilities and its world-class scientists, can revolutionize science in the years to come."

Kao joined SLAC in 2010 from Brookhaven National Laboratory, where he served as chairperson of the National Synchrotron Light Source. While at NSLS, Kao led significant upgrades to the light source's scientific programs and facilities and developed new science programs for NSLS-II. His research focuses on X-ray physics, superconductivity, magnetic materials and the properties of materials under high pressure.

"I'm honored to be asked to lead SLAC, a truly exceptional national laboratory," Kao said. "It is a place not only known for incredible accomplishments over the last 50 years in the arena of high-energy physics, but it has established itself as one of the world's premier laboratories for particle astrophysics and cutting-edge research in X-ray science. It's a lab with a talented and dedicated staff and an extremely bright future, one that will help solve some of the greatest scientific challenges facing the world today. I am very much looking forward to working with everyone at SLAC, Stanford and the DOE to lead the lab into its next successful chapter."

In Brief

Find information faster with Fermilab's new Test Beam Facility website

The new Fermilab Test Beam Facility website is up.

Today the Fermilab Test Beam Facility is unveiling its new and improved website. The new look will have a format more akin to the standard Fermilab website, which will help with navigation around the site's various sections.

The website's new content and navigation is based on recurring questions from the site's past visitors who asked for clarification on some sections. For example, the page on how to become a Fermilab user now has additional, more detailed steps, and the beam section is now easier to navigate to find the information you need.

The website also has a news box on its home page that will notify viewers of the latest facility news, such as when the facility will be taking requests for beam in July. The news box will also include a link that will direct viewers to the request procedure.

Two distinct heavy quarks living together

The proper-decay-length (top) and the invariant-mass (bottom) distributions of the Bc candidates, along with the fit projections.

The Bc meson is the only meson that consists of two distinct heavy quarks, the bottom quark and the charm quark. It was first discovered by CDF in 1998 from about 20 Bc decay events with a neutrino in the final state. The doubly heavy composition of the Bc meson means that its lifetime is shorter than that of the other B mesons, since both the bottom quark and the charm quark can contribute to the decay of the Bc.

Measuring the lifetime of the Bc improves our understanding of quark properties such as the quark masses and also contributes to our understanding of how quarks bind to each other.

Previously, all measurements of the lifetime of the Bc were made in decays with a neutrino in the final state. The neutrino escapes undetected and corrections are needed to model the momentum of the Bc meson in order to measure its lifetime. Now CDF researchers have measured the Bc lifetime for the first time in an all-hadronic decay mode, Bc-J/ψ π-. We measure all the decay particles, including the negative pion and two oppositely charged muons, which arise from the decay of the J/ψ particle.

The lifetime of the Bc meson is determined by a simultaneous fit to the lifetime and the mass of the Bc candidate events.

Using data from about 270 Bc decay events collected at the CDF II detector, CDF researchers measure the Bc lifetime to be 0.452 ± 0.048 (stat) ± 0.027 (syst) picoseconds, nearly four times shorter than that of the Bu meson. This measurement has a comparable precision with the world's best measurement and confirms the earlier experimental work and the theoretical predictions of the Bc lifetime. This work is also the topic of the Ph.D. dissertation of Hao Song at the University of Pittsburgh.

Recycled photons set fresh quantum computing record

From New Scientist, Oct. 23, 2012

Reusing old computer parts sounds like a terrible way to boost processing power, but it has enabled a quantum computer to set a new algorithmic record.

Anthony Laing and colleagues at the University of Bristol, UK, have used recycled quantum bits, or qubits, to carry out a quantum calculation known as Shor's algorithm on a larger number than ever before.
