Particle Physics Seminar: Exotic hadrons containing b and \bar{b} quarks

Abstract:

We review the status and recent results on exotic hadrons containing b\bar{b} quarks. Experimental data are provided by the BaBar, Belle and Belle II experiments. Any hadron with a structure more complex than q\bar{q} meson or qqq baryon is called exotic. The first unambiguous exotic hadron was observed in 2003; now a few tens of them are known. Some of the exotic hadrons have "molecular" structure: they are similar to nuclei in which nucleons are substituted by heavy mesons (D or B). Not all exotic hadrons can be explained by molecular models.
