The anomalous magnetic moment of the muon in the Standard Model: an update Open
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_μ$, updating the first White Paper (WP20) [1]. The pure QED and electroweak contributions have been further consolidated, while hadronic contr…

Radiative corrections and Monte Carlo tools for low-energy hadronic cross sections in $e^+ e^-$ collisions Open
We present the results of Phase I of an ongoing review of Monte Carlo tools relevant for low-energy hadronic cross sections. This includes a detailed comparison of Monte Carlo codes for electron–positron scattering into a muon pair, pion p…

Pion pair production in e+e− annihilation at next-to-leading order matched to Parton Shower Open
A bstract The pion pair production in e + e − annihilation at flavour factories plays a crucial role in the determination of the hadronic contribution to the muon anomalous magnetic moment. The recent CMD-3 measurement of the pion form fac…

Lepton pair production in muon-nucleus scattering Open
The MUonE experiment aims at providing a novel determination of the leading hadronic contribution to the muon anomalous magnetic moment through the study of elastic muon-electron scattering. Since the initial-state electrons are bound in a…

A teaching-learning sequence on colour in the context of a motivational stage for high school students Open
In this article we present a Teaching-Learning Sequence (TLS) on colour performed in the non-formal setting of a vocational stage with a sample of N=38 18-year-old high school students. Based both on previous educational research and the a…

High precision calculations for the MUonE experiment Open
The anomalous magnetic moment of the muon \\(a_\\mu=(g-2)_\\mu/2\\) has been measured at the Brookhaven National Laboratory in 2001 and recently at the Fermilab Muon \\(g-2\\) Experiment. The results deviate by 4.2 \\(\\sigma\\) from the S…

Neutral pion production in muon-electron scattering at MUonE Open
The value of the anomalous magnetic moment of the muon, $a_\mu = (g-2)_\mu / 2$, is a fundamental quantity in particle physics. Its most precise experimental measurement yields a deviation of 4.2$\sigma$ from the theoretical prediction wit…
