(DOE/Fermi National Accelerator Laboratory) Physicists of the DZero experiment at the US Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b.

The particle contains two strange quarks and a bottom quark. It is an exotic relative of the much more common proton and weighs about six times the proton mass.
