Isospin-1/2 Dπ scattering and the lightest D 0 ∗ $$ {D}_0^{\ast } $$ resonance from lattice QCD
Journal of High Energy Physics, 2021 Isospin-1/2 Dπ scattering amplitudes are computed using lattice QCD, working in a single volume of approximately (3.6 fm)3 and with a light quark mass corresponding to m π ≈ 239 MeV.

Gauge-equivariant flow models for sampling in lattice field theories with pseudofermions [PDF]
Physical Review D, 2022 This work presents gauge-equivariant architectures for flow-based sampling in fermionic lattice field theories using pseudofermions as stochastic estimators for the fermionic determinant.

Fermion-bag inspired Hamiltonian lattice field theory for fermionic quantum criticality [PDF]
Physical Review D, 2019 Motivated by the fermion-bag approach, we construct a new class of Hamiltonian lattice field theories that can help us to study fermionic quantum critical points, particularly those with four-fermion interactions.

Field Theory on a Supersymmetric Lattice [PDF]
, 1995 A lattice-type regularization of the supersymmetric field theories on a supersphere is constructed by approximating the ring of scalar superfields by an integer-valued sequence of finite dimensional rings of supermatrices and by using the differencial ...

The continuum and leading twist limits of parton distribution functions in lattice QCD
Journal of High Energy Physics, 2021 In this study, we present continuum limit results for the unpolarized parton distribution function of the nucleon computed in lattice QCD. This study is the first continuum limit using the pseudo-PDF approach with Short Distance Factorization for ...

Lattice field theory with torsion [PDF]
Physical Review D, 2019 Inspired by the duality between gravity and defects in crystals, we study lattice field theory with torsion. The torsion is realized by a line defect of a lattice, namely, a dislocation. For the first application, we perform the numerical computation for

Krylov complexity in quantum field theory, and beyond [PDF]
Journal of High Energy Physics, 2022 We study Krylov complexity in various models of quantum field theory: free massive bosons and fermions on flat space and on spheres, holographic models, and lattice models with a UV-cutoff.

Dilaton Effective Field Theory [PDF]
Universe, 2022 We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure.
