FLAG Review 2021

Y. Aoki et al.

Summary: In this review, lattice results related to pion, kaon, D-meson, B-meson, and nucleon physics are discussed, including determination of light-quark masses, form factor in semileptonic K -> pi transition, decay constant ratio, low-energy constants in Chiral Perturbation Theory, B-K parameter, heavy-quark quantities, strong coupling constant, and nucleon matrix elements.

Extraction of B-s -> D-s(()*()) form factors from N-f=2 lattice QCD

Benoit Blossier et al.

Summary: We report on a two-flavor lattice QCD study of B-s -> D-s and B-s -> D-s* decays, parametrized by the form factors G, h(A1), h(A2), and h(A3) in the heavy quark limit. The results of this study can provide experience and insights for future lattice QCD simulations with N-f > 2 and physical quark masses.

The renormalised O(a) improved vector current in three-flavour lattice QCD with Wilson quarks

Jochen Heitger et al.

Summary: In this study, non-perturbative determination of the improvement coefficient and renormalisation factor in three-flavour improved lattice QCD was conducted based on massive chiral Ward identities. The results showed significant differences between the improvement coefficient of the local vector current and one-loop perturbative estimates.

Ratio of flavour non-singlet and singlet scalar density renormalisation parameters in Nf=3 QCD with Wilson quarks: ALPHA Collaboration

Jochen Heitger et al.

Summary: In this study, the normalization factor rm equivalent to ZS/ZS0 was determined non-perturbatively using lattice QCD simulations. The calculation involved the computation of quark masses with Wilson fermions and the renormalization of nucleon matrix elements of scalar densities. The results cover gauge couplings corresponding to lattice spacings below 0.1fm.
