A strategy for B-physics observables in the continuum limit / Sommer, Rainer (DESY, Zeuthen ; Humboldt U., Berlin) ; Conigli, Alessandro (CSIC, Madrid ; Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Frison, Julien (DESY, Zeuthen) ; Fritzsch, Patrick (TCD, Dublin) ; Gérardin, Antoine (Marseille, CPT) ; Heitger, Jochen (U. Munster) ; Herdoiza, Gregorio (CSIC, Madrid) ; Kuberski, Simon (CERN ; Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Pena, Carlos (CSIC, Madrid) ; Simma, Hubert (DESY, Zeuthen)
In a somewhat forgotten paper [1] it was shown how to perform interpolations between relativistic and static computations in order to obtain results for heavy-light observables for masses from, say, mcharm to mbottom. All quantities are first continuum extrapolated and then interpolated in 1/mh=1/mheavy. [...]

FLAG Review 2021 / Flavour Lattice Averaging Group (FLAG) Collaboration
We review lattice results related to pion, kaon, D-meson, B-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factor f+(0) arising in the semileptonic Kπ transition at zero momentum transfer, as well as the decay constant ratio fK/fπ and its consequences for the CKM matrix elements Vus and Vud.

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure constant α and is broken down into pure QED, electroweak, and hadronic contributions. [...]

Non-Perturbative Renormalisation and Running of BSM Four-Quark Operators in Nf=2 QCD / Dimopoulos, Petros (Enrico Fermi Ctr., Rome ; Rome U., Tor Vergata) ; Herdoíza, Gregorio (Madrid, IFT ; Madrid, Autonoma U.) ; Papinutto, Mauro (INFN, Rome ; Rome U.) ; Pena, Carlos (Madrid, IFT ; Madrid, Autonoma U.) ; Preti, David (Madrid, IFT ; Madrid, Autonoma U. ; INFN, Turin) ; Vladikas, Anastasioss (INFN, Rome3 ; Rome U., Tor Vergata) /ALPHA Collaboration
We perform a non-perturbative study of the scale-dependent renormalisation factors of a complete set of dimension-six four-fermion operators. The renormalisation-group (RG) running is determined in the continuum limit for a specific Schr\"dinger Functional (SF) renormalisation scheme in the framework of lattice QCD with two dynamical flavours ( Nf=2 ).

B-physics computations from Nf=2 tmQCD / ETM Collaboration
We present an accurate lattice QCD computation of the b-quark mass, the B and Bs decay constants, the B-mixing bag-parameters for the full four-fermion operator basis, as well as estimates for \xi and f_{Bq}\sqrt{B_q} extrapolated to the continuum limit and the physical pion mass. We have used Nf = 2 dynamical quark gauge configurations at four values of the lattice spacing generated by ETMC. [...]

B-physics from Nf=2 tmQCD: the Standard Model and beyond / ETM Collaboration
We present a lattice QCD computation of the b-quark mass, the B and B_s decay constants, the B-mixing bag parameters for the full four-fermion operator basis as well as determinations for \xi and f_{Bq}\sqrt{B_i^{(q)}} extrapolated to the continuum limit and to the physical pion mass. We used N_f = 2 twisted mass Wilson fermions at four values of the lattice spacing with pion masses ranging from 280 to 500 MeV. [...]

We present a precise lattice QCD determination of the b-quark mass, of the B and Bs decay constants and first results for the B-meson bag parameters. For our computation we employ the so-called ratio method and our results benefit from the use of improved interpolating operators for the B-mesons. [...]

Non-perturbative renormalisation of Delta F=2 four-fermion operators in two-flavour QCD / Dimopoulos, P. (INFN, Rome2 ; Rome U., Tor Vergata) ; Herdoiza, G. (DESY) ; Palombi, F. (CERN) ; Papinutto, M. (CERN) ; Pena, C. (Madrid, Autonoma U.) ; Vladikas, A. (INFN, Rome2 ; Rome U., Tor Vergata) ; Wittig, H. (Mainz U., Inst. Kernphys.)
Using Schroedinger Functional methods, we compute the non-perturbative renormalisation and renormalisation group running of several four-fermion operators, in the framework of lattice simulations with two dynamical Wilson quarks. Two classes of operators have been targeted: (i) those with left-left current structure and four propagating quark fields/ (ii) all operators containing two static quarks. [...]
