Fermilab's CDF Observes Omega-sub-b Baryon
June 29, 2009
At a recent physics seminar at the U.S. Department of Energy's Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the Collider Detector at Fermilab (CDF) experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton, and has about six times the proton's mass.
