Constraining $1 + J \to 2$ coupled-channel amplitudes in finite-volume

Raul A. Briceno, Jozef J. Dudek, Luka Leskovec

Whether one is interested in accessing the excited spectrum of hadrons or testing the standard model of particle physics, electroweak transition processes involving multi-hadron ch…

P-wave nucleon-pion scattering amplitude in the $Δ (1232)$ channel from lattice QCD

Giorgio Silvi, Srijit Paul, Constantia Alexandrou +9

We determine the $Δ (1232)$ resonance parameters using lattice QCD and the Lüscher method. The resonance occurs in elastic pion-nucleon scattering with $J^{P} = 3/ 2^{+}$ in the isospin $I…

Investigation of Doubly Heavy Tetraquark Systems using Lattice QCD

Martin Pflaumer, Luka Leskovec, Stefan Meinel +1

We search for possibly existent bound states in the heavy-light tetraquark channels with quark content $b ˉ b ˉ u d$ , $b ˉ b ˉ u s$ and $b ˉ c ˉ u d$ using lat…

$I = 1/2$ $S$ -wave and $P$ -wave $K π$ scattering and the $κ$ and $K^{*}$ resonances from lattice QCD

Gumaro Rendon, Luka Leskovec, Stefan Meinel +6

We present a lattice-QCD determination of the elastic isospin- $1/2$ $S$ -wave and $P$ -wave $K π$ scattering amplitudes as a function of the center-of-mass energy using Lüscher's meth…

Lattice QCD investigation of a doubly-bottom $b ˉ b ˉ u d$ tetraquark with quantum numbers $I (J^{P}) = 0 (1^{+})$

Luka Leskovec, Stefan Meinel, Martin Pflaumer +1

We use lattice QCD to investigate the spectrum of the $b ˉ b ˉ u d$ four-quark system with quantum numbers $I (J^{P}) = 0 (1^{+})$ . We use five different gauge-link ensembles wit…

Towards the P-wave nucleon-pion scattering amplitude in the $Δ (1232)$ channel

Srijit Paul, Giorgio Silvi, Constantia Alexandrou +9

We use lattice QCD and the Lüscher method to study elastic pion-nucleon scattering in the isospin $I = 3/2$ channel, which couples to the $Δ (1232)$ resonance. Our $N_{f} = 2 + 1$ flavor…
