From Big to Small, BABAR Collaborations Work Together

Philippe Grenier, Peter Kim, Silke Nelson, Veronique Ziegler and Chris West are all breathing a sigh of relief after four months of exhausting analysis and peer review. This analysis group within the larger BABAR collaboration is celebrating last week's successful trip to the International Conference on High Energy Physics (ICHEP), where they announced the detection of the ηb particle (pronounced "eta-sub-b"). The paper announcing the ηb bottomonium results was accepted by the journal Physical Review Letters on July 15, 2008. Though most of the analysis was done by the five SLAC physicists, the author list goes on for two pages. For every one of BABAR's several-hundred collaborators, this is a job well done.

From a wide view, this large collaboration functions as a single entity. Over BABAR's eight-year run on the PEP-II ring at SLAC, every member of the collaboration has contributed to the tasks that keep an experiment of this size running. That includes working on the detector, and collecting and filtering data. But while the BABAR experiment requires support from a large number of scientists and engineers, it also relies on smaller groups within the collaboration to perform data analysis and peer review.  Read more...
