Long Talk (20 mins) Lattice Physics


Daniel Yeo (University of Cambridge)


With perturbative QCD unable to explain the phenomenon of confinement and predict the spectrum/dynamics of hadrons that comes with it, an alternative framework must be used. Lattice QCD along with the two-particle finite-volume formalism can be used to obtain scattering amplitudes non-perturbatively, whose analytic structure yields information about hadronic resonances.
      In this talk, I will discuss my recent project using this formalism to investigate $DK$ scattering in the $J^P=0^+$ open-charm sector with $SU(3)$ flavour symmetry. By considering equal up, down, and strange quark masses, the pole structure of this sector can be resolved into different $SU(3)$ flavour irreps and studied. We find a pole in the conventional flavour irrep consistent with quark model predictions and interesting physics in an exotic flavour sector.
