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…

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 $I (J^{P}) = 0 (1^{+})$ …

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 In particular, the Lüscher method is no longer applicable in the…

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…

Towards the quark mass dependence of $T_{cc}^{+}$ from lattice QCD

Sara Collins, Alexey Nefediev, M. Padmanath +1

The $D D^{*}$ scattering phase shifts in the $T_{cc}^{+} = cc u ˉ d ˉ$ channel are extracted from lattice QCD for five different charm quark masses and a fixed light-quark mass corr…

Doubly charmed tetraquark: isospin channels and diquark-antidiquark interpolators

Emmanuel Ortiz-Pacheco, Sara Collins, Luka Leskovec +2

We perform a lattice simulation to investigate the doubly charmed tetraquark $T_{cc}^{+}$ observed by the LHCb collaboration, slightly below the $D^{*+} D^{0}$ threshold, with flavor co…

Charmonia in moving frames

S. Prelovsek, G. Bali, S. Collins +4

Lattice simulation of charmonium resonances with non-zero momentum provides additional information on the two-meson scattering matrices. However, the reduced rotational symmetry in…
