JHU Particle Physics News Discovery of the Sigma_b Professor Petar Maksimovic and graduate student Jennifer Pursley along with their collaborators from New Mexico and Fermilab have discovered a new spin 1/2 baryon consisting of a b-quark and two light quarks. Their work has been reported in the CERN Courier and was the only particle physics entry in the APS Physics News for 2006. Polarization Puzzle in the Vector-Vector decays of B Mesons Professor Andrei Gritsan, graduate student Yanyan Gao and postdoc Zijin Guo have analyzed the decays of spin-0 B mesons into pairs of spin-1 (vector) mesons. They find the puzzling result that the daughter particles are much more likely to have their spins aligned with their decay directions than is naively expected. This work which is sensitive to an important class of virtual corrections is reported in a recent issue of SLAC Today. Penguins waddle in the decays of B Mesons Professor Andrei Gritsan, graduate student Yanyan Gao and UC Berkeley collaborator Yuri Kolomensky have observed the decays of B mesons into pairs of rho mesons. They find a surprising large signal which is sensitive to the effects of "penguin" processes. Understanding these is essential to the study of CP Violation in B meson decays. Their work is described in a recent issue of SLAC Today. The story of Randall and Sundrum The now famous work of Lisa Randall and JHU Professor Raman Sundrum on warped extra dimensions is described in a New York Times article . Some may be surprised by the role of high calorie desserts in the work. No one has ever said that elementary particle physics is a healthy profession!
