Form factors for semileptonic B-decays with HISQ light quarks and clover b-quarks in Fermilab interpretation
/ Jeong, Hwancheol (Indiana U.) ; DeTar, Carleton (Utah U.) ; El-Khadra, Aida X. (Tata Inst. ; Bielefeld U. ; CERN ; Kaiserslautern U. ; Illinois U., Urbana) ; Gámiz, Elvira (CAFPE, Granada ; Granada U., Theor. Phys. Astrophys.) ; Gelzer, Zechariah (Tata Inst. ; Bielefeld U. ; CERN ; Kaiserslautern U. ; Illinois U., Urbana) ; Gottlieb, Steven (Indiana U.) ; Jay, William (MIT, Cambridge, CTP) ; Kronfeld, Andreas (Fermilab) ; Lytle, Andrew (Tata Inst. ; Bielefeld U. ; CERN ; Kaiserslautern U. ; Illinois U., Urbana) ; Vaquero, Alejandro (Zaragoza U.)
We compute the vector, scalar, and tensor form factors for the $B\to \pi$, $B\to K$, and $B_s\to K$ amplitudes, which are needed to describe semileptonic $B$-meson decay rates for both the charged and neutral current cases. We use the highly improved staggered quark (HISQ) action for the sea and light valence quarks. [...]

50 Years of Quantum Chromodynamics
/ Gross, Franz (Jefferson Lab ; William-Mary Coll.) ; Klempt, Eberhard (Bonn U., HISKP) ; Brodsky, Stanley J. (SLAC) ; Buras, Andrzej J. (TUM-IAS, Munich) ; Burkert, Volker D. (Jefferson Lab) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jakobs, Karl (Freiburg U.) ; Meyer, Curtis A. (Carnegie Mellon U.) ; Orginos, Kostas (Jefferson Lab ; William-Mary Coll.) ; Strickland, Michael (Kent State U.) et al.
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73 and following developments and results up to the present day. Topics include a review of the earliest theoretical and experimental foundations; the fundamental constants of QCD; an introductory discussion of lattice QCD, the only known method for obtaining exact predictions from QCD; methods for approximating QCD, with special focus on effective field theories; QCD under extreme conditions; measurements and predictions of meson and baryon states; a special discussion of the structure of the nucleon; techniques for study of QCD at high energy, including treatment of jets and showers; measurements at colliders; weak decays and quark mixing; and a section on the future, which discusses new experimental facilities or upgrades currently funded.

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 $K \to \pi$ transition at zero momentum transfer, as well as the decay constant ratio $f_K/f_\pi$ and its consequences for the CKM matrix elements $V_{us}$ and $V_{ud}$.

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 $\alpha$ and is broken down into pure QED, electroweak, and hadronic contributions. [...]

The scaling dimension of low lying Dirac eigenmodes and of the topological charge density
/ MILC Collaboration
As a quantitative measure of localization, the inverse participation ratio of low lying Dirac eigenmodes and topological charge density is calculated on quenched lattices over a wide range of lattice spacings and volumes. Since different topological objects (instantons, vortices, monopoles, and artifacts) have different co-dimension, scaling analysis provides information on the amount of each present and their correlation with the localization of low lying eigenmodes..
