A Hadron is a kind of particle, made of quarks. There are two kinds of hadrons, baryons (made out of three quarks) and mesons (made out of a quark and a quirky quark known as an antiquark).
The particle of interest is made up of an up quark, a strange quark, and a heavy bottom quark. I've known a few bluegrass bands that fit that description, but this particle is called the Xi-sub-b baryon.
The observation was made at the Collider Detector at Fermilab (CDF) .

The neutral Xi-sub-b belongs to the family of bottom baryons, which are about six times heavier than the proton and neutron because they all contain a heavy bottom quark. The particles are produced only in high-energy collisions, and are rare and very difficult to observe*.
