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."

    Favorite quotes from TFA:

    "existence of the Xi-sub-b has been predicted for some time"

    "the Xi-sub-b was observed in 25 instances among almost 500 trillion proton-antiproton collisions"

    Nope. They made them.

    It's possible, even likely, that something somewhere else (supernova, the big bang, etc.) made some in olden times. But these were brand-spankin' new.

    If you'd prefer a link to the actual release instead ofconceivablytech's take on it:

    does anyone have the arXiv link to the actual paper, not the PR fluff?
