The structure of the pion at large
Isaac Zhu, Fernando Romero-López, Phiala E. Shanahan
We compute the pion quark momentum fraction in the large- limit using the Twisted Eguchi-Kawai (TEK) reduced model. Gauge configurations for different values of the lattice sp…
Quark-mass dependence of two-nucleon scattering
Jorge Baeza-Ballesteros, André Baião-Raposo, Davide Laudicina +13
Understanding how the properties of the visible Universe depend on the parameters of the Standard Model of particle physics requires \emph{ab initio} theoretical computations. To t…
Improving hadron creation operators for charmonium, glueballs and baryons
Juan Andrés Urrea-Niño, John Bulava, Nikolai Husung +5
Constructing hadron creation operators which properly sample the finite-volume energy spectrum is a fundamental step in lattice QCD spectroscopy and scattering calculations. Operat…
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…
Learning the generating functional for variance reduction in lattice QCD
Ryan Abbott, Yang Fu, Daniel C. Hackett +3
The generating functional in quantum field theory provides the natural framework for constructing correlation functions as derivatives with respect to source operators. We present…
as a precision test of a new four flavor Domain Wall Fermion action
Renwick J. Hudspith, Nicolas Garron, Zack Hall +12
We present a new set of lattice QCD ensembles with four flavors of smeared Möbius Domain Wall Fermions with good chiral symmetry and small fifth-dimensional extent. A modest amount…
Investigating the role of tetraquark operators in lattice QCD studies of the and resonances
Andrew D. Hanlon, Daniel Darvish, Sarah Skinner +7
The role of tetraquark operators in studying the isodoublet strange and isovector nonstrange scalar mesons in lattice QCD is examined using an ensemble with $m_π\app…
Variance reduction in lattice QCD observables via normalizing flows
Ryan Abbott, Denis Boyda, Yang Fu +5
Normalizing flows can be used to construct unbiased, reduced-variance estimators for lattice field theory observables that are defined by a derivative with respect to action parame…
