Title: Excited charm/charmonium mesons and exotics from lattice QCD
Abstract: I will discuss some recent progress in studying studying charm and charmonium mesons using lattice QCD. The spectroscopy and interactions of hadrons probe the strongly-interacting regime of QCD, and in recent years experiments have observed a number of puzzling hadrons that challenge our understanding of the strong interaction. Lattice QCD provides a method for performing first-principles computations of the properties of hadrons and hence a QCD-based understanding of the phenomena. However, the majority of hadrons decay strongly, i.e. they are resonances, and lattice calculations of these are challenging. I will present a selection of recent work that has advanced our understanding of hadrons including results relevant for the exotic doubly-charmed Tcc(3875) observed by LHCb, and scalar and tensor charmonium resonances.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
