CDF Discovers Exotic New Baryons

Graduate student Christopher Marino and postdoc Anyes Taffard worked on the high speed digital processing system that made the discovery possible Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced the discovery of two rare types of particles, exotic relatives of the much more common proton and neutron.

Kevin Pitts, an associate professor of physics at Illinois, is one of the co-leaders of the CDF physics group performing this measurement.

"This is the first observation of the Sigma-sub-b [Σb], baryon, which is an extremely heavy cousin to the proton, much like an atom of iron is an extremely heavy cousin to an atom of hydrogen,” Pitts explained. “We have just added to the mankind’s knowledge of the ‘periodic table of baryons’.” Read more...
