BMW/DMZ calculation of the hadronic vacuum polarisation for the muon magnetic moment

Finn M. Stokes, Alessandro Cotellucci, Michel Davier +11

For twenty years, a persistent discrepancy between experimental measurements and theoretical calculations of the muon anomalous magnetic moment have provided tantalising hints of n…

GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1878

GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios $\sim 32$ and $\sim 69$ , respectively…

Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\%

A. Boccaletti, Sz. Borsanyi, A. Cotellucci +19

We present a new lattice QCD calculation of the leading order hadronic vacuum polarization (LO-HVP) contribution to the muon anomalous magnetic moment $a_{I^} ¼$ . We reduce uncertainti…

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

R. Aliberti, T. Aoyama, E. Balzani +232

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_{I^} ¼$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

Data-based form factor corrections between the two-pion $I ¨ $ and $e^{+} e^{-}$ spectral functions

Michel Davier, Bogdan Malaescu, Zhiqing Zhang

The $I ¨ $ spectral functions are an alternative to $e^{+} e^{-}$ cross-sections, where different measurements are not consistent, for computing the hadronic vacuum contribution to the mu…

A search for baryogenesis and dark matter in $B^{+} \to I^_{c}^{+} + invisible$ decays

BABAR Collaboration

A mechanism of baryogenesis and dark matter production via $B$ -meson oscillations and decays has recently been proposed to explain the observed dark matter abundance and matter-ant…
