Caption: Once produced, the decay of the Omega-sub-b proceeds like fireworks. The particle travels about a millimeter before it disintegrates into two intermediate particles called J/Psi and Omega-minus. The J/Psi then promptly decays into a pair of muons. The Omega-minus baryon, on the other hand, can travel several centimeters before decaying into yet another unstable particle called a Lambda baryon along with a long-lived particle called kaon. The Lambda baryon, which has no electric charge, also can travel several centimeters prior to decaying into a proton and a pion.
