Three months ago the DZero experiment at the Tevatron collider, the most powerful particle accelerator machine currently operating, announced the discovery of the first baryon containing quarks from all three known generations of matter. This particle, the Xi_b (aka Cascade b), is make of a "beauty" quark, a "down" quark, and a "strange" quark, all combined together to create a strangely beautiful baryon. The discovery of this particle, along with the statistical techniques used in the discovery, will be presented in detail.
