Accessing the Wess-Zumino-Witten term using Lattice QCD
Fernando Romero-López, Stephen R. Sharpe
The Wess-Zumino-Witten interaction in chiral perturbation theory is a manifestation of chiral anomalies. One of its consequences is the presence of a nonvanishing $K \overline K \t…
Three-body study of the from lattice QCD
Herzallah Alharazin, André Baião Raposo, John Bulava +7
We discuss an ongoing first lattice study of the doubly-charmed tetraquark (3875) via a three-body approach. We investigate the system in the , sector, w…
Finite-volume formalism for at maximal isospin
Maxwell T. Hansen, Fernando Romero-López, Stephen R. Sharpe
We extend the relativistic field theoretic finite-volume formalism to scattering states at maximal isospin, . As in previous work using the relativistic field theory…
Comparison of integral equations used to study for a stable
Sebastian M. Dawid, Fernando Romero-López, Stephen R. Sharpe
We perform a detailed comparison between three formalisms used in recent studies of scattering, which aim to understand the properties of the doubly-charmed tetraquark, $T_{…
Two- and three-meson scattering amplitudes with physical quark masses from lattice QCD
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We study systems of two and three mesons composed of pions and kaons at maximal isospin using four CLS ensembles with fm, including one with approximately physica…
QCD predictions for physical multimeson scattering amplitudes
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We use lattice QCD calculations of the finite-volume spectra of systems of two and three mesons to determine, for the first time, three-particle scattering amplitudes with physical…
Finite- and infinite-volume study of scattering
Sebastian M. Dawid, Fernando Romero-López, Stephen R. Sharpe
We develop a comprehensive framework for extracting the pole position and properties of the doubly-charmed tetraquark from lattice QCD data using the relativis…
Three-particle formalism for multiple channels: the system in isosymmetric QCD
Zachary T. Draper, Stephen R. Sharpe
We generalize previous three-particle finite-volume formalisms to allow for multiple three-particle channels. For definiteness, we focus on the two-channel and $K \overline K…
The three-pion -matrix at NLO in ChPT
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3
The three-particle -matrix, , is a scheme-dependent quantity that parametrizes short-range three-particle interactions in the relativistic-field-the…
Incorporating effects and left-hand cuts in lattice QCD studies of the
Maxwell T. Hansen, Fernando Romero-López, Stephen R. Sharpe
We generalize the relativistic field-theoretic three-particle finite-volume scattering formalism to describe generic systems in the charm sector. This includes the isos…
