Radiative decays of the $h_{c}$ meson from lattice QCD

Mischa Batelaan, Jozef J. Dudek, Robert G. Edwards

We explore, for the first time in lattice QCD, the radiative decays to $γ η$ and $γ η^{'}$ of the $J^{P C} = 1^{+-}$ charmonium state, $h_{c}$ . This work expands upon a previous calculation…

$D D ˉ$ interactions are weak near threshold in QCD

David J. Wilson, Jozef J. Dudek, Robert G. Edwards +1

We study near-threshold $D D ˉ$ scattering in $S$ and $D$ -wave to determine whether or not resonances or bound states are present. Working in the approximation where charm-annih…
