Following updates in the compilation of $e^+e^-\rightarrow{\rm hadrons}$ data, this work presents re-evaluations of the hadronic vacuum polarisation contributions to the anomalous magnetic moment of the electron ($a_e$), muon ($a_\mu$) and tau lepton ($a_\tau$), to the ground-state hyperfine splitting of muonium and also updates the hadronic contributions to the running of the QED coupling at the mass scale of the $Z$ boson, $\alpha(M_Z^2)$. Combining the results for the hadronic vacuum… 
Leptoquark-vectorlike quark model for $m_W$ (CDF), $(g-2)_\mu$, $R_{K^{(\ast)}}$ anomalies and neutrino mass
Very recently, a substantial 7 σ deviation of the W -boson mass from the Standard Model (SM) prediction has been reported by the CDF collaboration. Furthermore, the Muon g-2 Experiment recently
Muon $(g-2)$ and Thermal WIMP DM in ${\rm U(1)}_{L_\mu-L_\tau} $ Models
U(1) L µ − L τ ≡ U(1) X model is anomaly free within the Standard Model (SM) fermion content, and can accommodate the muon ( g − 2) data for M Z (cid:48) ∼ O (10 − 100) MeV and g X ∼ (4 − 8) × 10 − 4
Next-to-leading-order QCD matching for ∆F = 2 processes in scalar leptoquark models
Abstract Leptoquarks provide viable solutions to the flavour anomalies, i.e. they can explain the tensions between the measurements and the Standard Model predictions of the anomalous magnetic
The tiny (g-2) muon wobble from small-μ supersymmetry
A new measurement of the muon anomalous magnetic moment, g μ − 2, has been reported by the Fermilab Muon g-2 collaboration and shows a 4 . 2 σ departure from the most precise and reliable calculation
Probing the dark axion portal with muon anomalous magnetic moment
We propose a new scenario of using the dark axion portal at one-loop level to explain the recently observed muon anomalous magnetic moment by the Fermilab Muon g-2 experiment. Both axion/axion-like
Hadronic light-by-light contribution to $$(g-2)_\mu $$ from lattice QCD: a complete calculation
We compute the hadronic light-by-light scattering contribution to the muon $$g-2$$ g - 2 from the up, down, and strange-quark sector directly using lattice QCD. Our calculation features

The MUonE experiment has been proposed to measure the differential cross section of μe elastic scattering, by colliding the 160 GeV muons of the CERN M2 beam with atomic electrons of thin target

This article reviews the status of lattice calculations of hadronic vacuum polarization and hadronic light-by-light scattering quantities, starting with the HVP, which has now reached sub-percent precision and requires a careful understanding of all sources of systematic errors.
