abstract

The cross section for the process $e^+e^-\to\pi^+\pi^-$ is measured in the c.m. energy range 1.04-1.38 GeV from 995 000 selected collinear events including 860000 $e^+e^-$ events, 82000 $\mu^+\mu^-$ events, and 33000 $\pi^+\pi^-$ events. The systematic and statistical errors of measuring the pion form factor are equal to 1.2-4.2 and 5-13%, respectively.

  1. Next-to-leading order FsQED corrections to radiative pion pair production

    hep-ph 2026-07 conditional novelty 6.0 of 10

    FsQED NLO structure-dependent corrections to radiative pion-pair production are at the permille (mass) to percent (angular/AFB) level, agree with GVMD, and are now in BabaYaga@NLO.

  2. Hadronic vacuum polarization in hydrogen-like atoms and ions amid the interplay of recoil and finite-size effects

    physics.atom-ph 2026-07 accept novelty 6.0 of 10

    The hVP contribution to the HFS in muonic hydrogen is 2.153(11) µeV, deviating from previous evaluations by ~10x the anticipated experimental precision, due to corrected recoil and finite-size interplay.

  3. The Muonic Portal to Vector Dark Matter:connecting precision muon physics, cosmology, and colliders

    hep-ph 2025-10 unverdicted novelty 6.0 of 10

    A new model with SU(2)_D symmetry and vector-like muons mediates vector dark matter, simultaneously addressing relic abundance and muon g-2 while identifying an off-resonance suppression mechanism for light DM and der...

  4. The anomalous magnetic moment of the muon in the Standard Model: an update

    hep-ph 2025-05 accept novelty 5.0 of 10

    The updated SM prediction for the muon anomalous magnetic moment is 116592033(62)×10^{-11}, showing no tension with the experimental average of 38(63)×10^{-11}.

  5. Searching for hadronic scale baryonic and dark forces at $(g-2)_\mu$'s lattice-vs-dispersion front

    hep-ph 2024-12 conditional novelty 5.0 of 10

    A flavor-universal GeV-scale vector boson's direct contribution to (g-2)_mu cancels against its on-shell contribution to the e+e- -> hadrons data when the data-driven HVP is used, redirecting the search to the lattice...

  6. New BaBar studies of high-order radiation and the new landscape of data-driven HVP predictions of the muon g-2

    hep-ex 2024-12 conditional novelty 4.0 of 10

    BaBar's higher-order radiation study suggests a Phokhara generator discrepancy that may bias KLOE and BESIII cross sections, reshaping the data-driven muon g-2 HVP landscape.

  7. The anomalous magnetic moment of the muon in the Standard Model

    hep-ph 2020-06 accept novelty 2.0 of 10

    The Standard Model value for the muon anomalous magnetic moment is 116591810(43)×10^{-11}, 3.7σ below the Brookhaven experimental measurement.
