The standard model (SM) of particle physics is the mathematical description of the
fundamental constituents and interactions of matter. Its last missing particle, the Higgs …

The situation of the experimental data used in the dispersive evaluation of the hadronic
vacuum polarization contribution to the anomalous magnetic moment of the muon is …

We present details on a new measurement of the muon magnetic anomaly, a μ=(g μ-2)/2.
The result is based on positive muon data taken at Fermilab's Muon Campus during the …

Belle II has reported the first evidence for B+→ K+ ν ν¯ with a branching ratio 2.7 σ higher
than the standard model expectation. We explain this and the MiniBooNE and muon …

We present the first data-driven result for a μ win, lqc, the isospin-limit light-quark connected
component of the intermediate-window Hadronic-vacuum-polarization contribution to the …

The cross section of the process e+ e-→ π+ π-has been measured in the center-of-mass
energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider …

The precision with which hadronic vacuum polarization (HVP) is obtained determines how
accurately important observables, such as the muon anomalous magnetic moment a μ or the …

We present a new lattice QCD calculation of the leading order hadronic vacuum polarization
contribution to the muon anomalous magnetic moment $ a_\mu $. We reduce uncertainties …

The production of a pair of τ leptons via photon–photon fusion, γγ→ ττ, is observed for the
first time in proton–proton collisions, with a significance of 5.3 standard deviations. This …
