Quantum mean estimation for lattice field theory
Physical Review D, 2023 We demonstrate the quantum mean estimation algorithm on Euclidean lattice field theories. This shows a quadratic advantage over Monte Carlo methods which persists even in presence of a sign problem, and is insensitive to critical slowing down. The algorithm is used to compute $π$ with and without a sign problem, a toy U(1) gauge theory model, and the ...

Implementing the three-particle quantization condition for π + π + K + and related systems
Journal of High Energy Physics, 2022 Recently, the formalism needed to relate the finite-volume spectrum of systems of nondegenerate spinless particles has been derived. In this work we discuss a range of issues that arise when implementing this formalism in practice, provide further ...

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.

More on the flavor dependence of m ϱ /f π
Journal of High Energy Physics, 2021 In previous work, [ arXiv:1905.01909 ], we have calculated the m ϱ /fπ ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation.

Nucleon momentum fraction, helicity and transversity from 2+1-flavor lattice QCD
Journal of High Energy Physics, 2021 A detailed analysis of the systematic uncertainties in the calculation of the isovector momentum fraction, 〈x〉 u − d , helicity moment, 〈x〉Δu − Δd , and the transversity moment, 〈x〉 δu − δd , of the nucleon is presented using high-statistics data on ...

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 ...

Relativistic N-particle energy shift in finite volume
Journal of High Energy Physics, 2021 We present a general method for deriving the energy shift of an interacting system of N spinless particles in a finite volume. To this end, we use the nonrelativistic effective field theory (NREFT), and match the pertinent low-energy constants to the ...

The flavor dependence of m ϱ /f π
Journal of High Energy Physics, 2019 We calculate the m ϱ /f π ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation. Keeping all systematic effects under full control we find no statistically significant N f
