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 $I (J^{P}) = 0 (1^{+})$ …

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…

$B \to I ¨ ℓ I^ˉ ½$ resonance form factors from $B \to I ¨ I ¨ ℓ I^ˉ ½$ in lattice QCD

Luka Leskovec, Stefan Meinel, Marcus Petschlies +3

The decay $B \to I ¨ ℓ I^ˉ ½$ is an attractive process for determining the magnitude of the smallest CKM matrix element, $∣ V_{u b} ∣$ , and can provide new insights into the origin…

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 In particular, the LÃ¼scher method is no longer applicable in the…
