Fermilab Scientists Discover New Particle

An anonymous reader writes "Fermilab today announced that scientists working at the CDF (Collision Detector at Fermilab) experiment confirmed the observation of a new particle, the Xi-sub-b. The Xi-sub-b is categorized as a baryon, which are formed of three quarks. Commonly known baryons include the proton as well as the neutron."

Really new?

My guess is they've discovered an old particle.

Yes. Speaker cables.

We haven't decided whether Xi-sub-b free cables or cables with a surplus of Xi-sub-b will sell better. But we'll be ready when marketing figures it out.
