[QUOTE="Geek, post: 2574890, member: 246624"] 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.
