Electromagnetic form factors and structure of the $T_{bb}$ tetraquark from lattice QCD

Ivan Vujmilovic, Sara Collins, Luka Leskovec +1

We present the first lattice QCD determination of the electromagnetic form factors of the exotic tetraquark $T_{bb} (bb u ˉ d ˉ)$ with quantum numbers $I (J^{P}) = 0 (1^{+})$ …

Strange partner of $T_{cc}^{+}$ from lattice QCD in $D^{()} D_{s}^{()}$ scattering

Tanishk Shrimal, Sara Collins, Priyajit Jana +2

We report on our lattice QCD study of coupled $D D_{s}^{*} - D^{*} D_{s}$ scattering in the $J^{P} = 1^{+}$ channel and elastic $D D_{s}$ scattering in the $J^{P} = 0^{+}$ channel, aimed at investigating t…

Electromagnetic form factors and structure of the $T_{bb}$ tetraquark

Ivan Vujmilovic, Sara Collins, Luka Leskovec +1

We present the first lattice QCD calculation of electromagnetic form factors of a tetraquark, focusing on the $T_{bb} = bb u ˉ d ˉ$ with quantum numbers $I (J^{P}) = 0 (1^{+})$ . The…

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…

Charmoniumlike Channels $1^{+}$ with Isospin $1$ from Lattice and Effective Field Theory

Mitja Sadl, Sara Collins, Zhi-Hui Guo +3

Many exotic charmoniumlike mesons have already been discovered experimentally, of which the $Z_{c}$ mesons with $I = 1$ are prominent examples. We investigate $J^{P C} = 1^{+\pm}$ states…
