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 $I^^{3} I^\cdot$ and $I^^{3} I^\cdot^{'}$ of the $J^{P C} = 1^{+-}$ charmonium state, $h_{c}$ . This work expands upon a previous calculat…

$D D ˉ$ 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…

Isotensor $I ¨ I ¨ I ¨ $ scattering with a $I ¨ $ resonant subsystem from QCD

RaÃºl A. BriceÃ±o, Maxwell T. Hansen, Andrew W. Jackura +2

This work presents a lattice quantum chromodynamics (QCD) determination of $I ¨ I ¨ I ¨ $ scattering amplitudes for the isospin-2 channel with angular momentum and parity $J^{P} = 1^{+}$ .…

$I^\cdot$ and $I^\cdot^{'}$ production in $J / I ¨ $ radiative decays from quantum chromodynamics

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

We present a first principles calculation within quantum chromodynamics (QCD) of the radiative decays of the $J / I ¨ $ into the light pseudoscalar mesons $I^\cdot$ and $I^\cdot^{'}$ . Within a latt…

$I^\cdot$ and $I^\cdot^{'}$ meson production in $J / I ¨ $ radiative decays from lattice QCD

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

We report on the computation of amplitudes describing the radiative decay processes $J / I ¨ \to I^^{3} I^\cdot$ and $J / I ¨ \to I^^{3} I^\cdot^{'}$ from first principles via lattice QCD. Using lattices w…
