Dispersive estimation of the LO hadronic contribution to the muon $g - 2$ : fitting incompatible $e^{+} e^{-}$ data

V. V. Bryzgalov, O. V. Zenin

Using an up-to-date compilation of $σ_{tot} (e^{+} e^{-} \to ha d r o n s)$ data we estimated the LO hadronic contribution to the muon anomalous magnetic moment, $a_{μ} (ha d, L O)$ . Incom…

A comment on the impact of CMD-3 $e^{+} e^{-} \to π^{+} π^{-}$ cross section measurement on the SM $g_{μ} - 2$ value

V. V. Bryzgalov, O. V. Zenin

We estimated an impact of the recent CMD-3 measurement of the $e^{+} e^{-} \to π^{+} π^{-}$ total cross section at $0.3 < s < 1.2$ GeV on the leading order hadronic contribution $a_μ^…

Ratios of helicity amplitudes for exclusive $ρ^{0}$ electroproduction on transversely polarized protons

The HERMES Collaboration, A. Airapetian, N. Akopov +74

Exclusive $ρ^{0}$ -meson electroproduction is studied by the HERMES experiment, using the 27.6 GeV longitudinally polarized electron/positron beam of HERA and a transversely polarized…
