More on the flavor dependence of m ϱ /f π

open access: yesJournal 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

open access: yesJournal 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 ...

Isospin-1/2 Dπ scattering and the lightest D 0 ∗ $$ {D}_0^{\ast } $$ resonance from lattice QCD

open access: yesJournal 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.

The continuum and leading twist limits of parton distribution functions in lattice QCD

open access: yesJournal 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

open access: yesJournal 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 ...

Soliton quantization in lattice field theories [PDF]

open access: yesCommunications in Mathematical Physics, 1987
Quantization of solitons in terms of Euclidean region functional integrals is developed, and Osterwalder-Schrader reconstruction is extended to theories with topological solitons. The quantization method is applied to several lattice field theories with solitons, and the particle structure in the soliton sectors of such theories is analyzed.
