2-flavour gauge theory with exponential clover Wilson fermions
Laurence Sebastian Bowes, Vincent Drach, Patrick Fritzsch +2
Composite Higgs models are a class of models proposed to address the hierarchy and naturalness problems associated with the Standard Model fundamental scalar Higgs. with tw…
The from Lattice QCD: Determining the Finite-volume Spectra
John Bulava, Bárbara Cid-Mora, Andrew D. Hanlon +8
This work presents technical details of determining the finite-volume energy spectra for the scattering amplitude of the coupled-channel from lattice QCD data. The i…
Lattice QCD studies of the baryon resonance and the and meson resonances: the role of exotic operators in determining the finite-volume spectrum
John Bulava, Danny Darvish, Andrew D. Hanlon +7
Studies of the baryon resonance and the and meson resonances using lattice QCD for pion masses near 200 MeV are presented. The -wave sca…
Low-lying baryon resonances from lattice QCD
John Bulava, Barbara Cid-Mora, Andrew D. Hanlon +8
Recent results studying the masses and widths of low-lying baryon resonances in lattice QCD are presented. The -wave scattering lengths for both total isospins an…
Three-pion scattering: From the chiral Lagrangian to the lattice
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3
In recent years, detailed studies of three-pion systems have become possible in lattice QCD. This has in turn led to interest in 3-to-3 scattering of pions in the chiral perturbati…
Lattice quantum chromodynamics at large isospin density: 6144 pions in a box
Ryan Abbott, William Detmold, Fernando Romero-López +6
We present an algorithm to compute correlation functions for systems with the quantum numbers of many identical mesons from lattice quantum chromodynamics (QCD). The algorithm is n…
Lattice QCD study of scattering and the resonance
John Bulava, Bárbara Cid-Mora, Andrew D. Hanlon +8
A lattice QCD computation of the coupled channel scattering amplitudes in the region is detailed. Results are obtained using a single ensemble of gauge fiel…
Two-pole nature of the from lattice QCD
John Bulava, Bárbara Cid-Mora, Andrew D. Hanlon +8
This letter presents the first lattice QCD computation of the coupled channel scattering amplitudes at energies near . These amplitudes contain the r…
Constraint of pionless EFT using two-nucleon spectra from lattice QCD
William Detmold, Fernando Romero-López, Phiala E. Shanahan
Finite-volume pionless effective field theory (FVEFT) at next-to-leading order (NLO) is used to analyze the two-nucleon lattice QCD spectrum of Ref.~\cite{Amarasinghe:20…
Normalizing flows for lattice gauge theory in arbitrary space-time dimension
Ryan Abbott, Michael S. Albergo, Aleksandar Botev +11
Applications of normalizing flows to the sampling of field configurations in lattice gauge theory have so far been explored almost exclusively in two space-time dimensions. We repo…
The Present and Future of QCD
P. Achenbach, D. Adhikari, A. Afanasev +400
This White Paper presents the community inputs and scientific conclusions from the Hot and Cold QCD Town Meeting that took place September 23-25, 2022 at MIT, as part of the Nuclea…
The isospin-3 three-particle -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…
Three relativistic neutrons in a finite volume
Zachary T. Draper, Maxwell T. Hansen, Fernando Romero-López +1
We generalize the relativistic field-theoretic (RFT) three-particle finite-volume formalism to systems of three identical, massive, spin- fermions, such as three neutrons. Thi…
Interactions of , and systems at maximal isospin from lattice QCD
Zachary T. Draper, Andrew D. Hanlon, Ben Hörz +3
We study the interactions of systems of two and three nondegenerate mesons composed of pions and kaons at maximal isospin using lattice QCD, specifically , and…
Multi-hadron interactions from lattice QCD
Fernando Romero-López
First-principles calculations of multi-hadron dynamics are a crucial goal in lattice QCD. Significant progress has been achieved in developing, implementing, and applying theoretic…
