dc.description.abstract | In this paper, we address the question of whether the almost four standard deviations difference between
theory and experiment for the muon anomalous magnetic moment aμ can be explained as a higher-order
Standard Model perturbation effect in the pion form factor measurements. This question has, until now,
remained open, obscuring the source of discrepancies between the measurements. We calculate the last
radiative corrections for the extraction of the pion form factor, which were believed to be potentially
substantial enough to explain the data within the Standard Model.We find that the corrections are too small
to diminish existing discrepancies in the determination of the pion form factor for different kinematical
configurations of low-energy BABAR, BES-III and KLOE experiments. Consequently, they cannot
noticeably change the previous predictions for aμ and decrease the deviations between theory and direct
measurements. To solve the above issues, new data and better understanding of low-energy experimental
setups are needed, especially as new direct aμ measurements at Fermilab and J-PARC will provide new
insights and substantially shrink the experimental error. | pl_PL |
