Speaker: Thomas Mehen (Duke University)
Title: "Application of EFT to X(3872) and Doubly Charm Baryons"

Abstract: The last 17 years have witnessed the discovery of a plethora of novel hadrons. Many of these - the so-called XYZ States - are novel excitations of heavy quarkonia above the open heavy meson threshold which don't fit into the quark model picture of quarkonia. Other recently discovered states include doubly charmed baryons and charmed pentaquarks. I will give an overview of this field and then describe two recent applications of effective field theory to the physics of these particles: 1) X(3872) is widely believed to be a very weakly bound state of charmed mesons. I describe a recent calculation of its dominant decay mode which leads to a new way of extracting its binding energy and testing its molecular character; 2) a recent analysis of corrections to heavy quark-diquark symmetry predictions for hyperfine splittings in doubly heavy baryons.
