Lattice study of $cc u ˉ s ˉ$ tetraquark channel in $D^{()} D_{s}^{()}$ scattering

Tanishk Shrimal, Sara Collins, Priyajit Jana +2

We present the first lattice QCD determination of coupled $D D_{s}^{*}$ and $D^{*} D_{s}$ scattering amplitudes in the $J^{P} = 1^{+}$ channel and elastic $D D_{s}$ scattering amplitude in the $J…

Doubly heavy tetraquarks from lattice QCD: incorporating diquark-antidiquark operators and the left-hand cut

S. Prelovsek, E. Ortiz-Pacheco, S. Collins +3

Lattice studies of the doubly-charm tetraquark $T_{cc} = cc u ˉ d ˉ$ require the determination of the $D D^{*}$ scattering amplitude, which most often incorporate only meson-meson i…

$T_{cc}^{+}$ via the plane wave approach and including diquark-antidiquark operators

Ivan Vujmilovic, Sara Collins, Luka Leskovec +3

The determination of the $D D^{*}$ scattering amplitude from lattice QCD is complicated by long-range interactions. In particular, the Lüscher method is no longer applicable in the…
