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…

Doubly charm tetraquark channel with isospin $1$ from lattice QCD

Lu Meng, Emmanuel Ortiz-Pacheco, Vadim Baru +3

Experimentally, the doubly charm tetraquark channel $cc q ˉ q ˉ$ with $q = u, d$ features an exotic hadron, $T_{cc}$ , with isospin $I = 0$ near the $D D^{*}$ threshold, while n…

$T_{cc}^{+}$ 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 In particular, the LÃ¼scher method is no longer applicable in the…
