Description
The development of radiative corrections and Monte Carlo tools for low-energy $e^+e^-$ experiments is relevant for high-precision tests of the Standard Model, such as the determination of the leading hadronic contribution to the muon $(g-2)$ or the electroweak precision fits.
Recently, there has been a renewed initiative to compare Monte Carlo tools. The main aim is to compare the available codes for benchmark scenarios relevant to both scan experiments (such as CMD) and radiative return experiments (such as KLOE). These codes include QED corrections at fixed order and/or resummation effects for $e^+e^- \rightarrow X^+X^- (\gamma) $ for $X\in \{e, μ, π\}$.
We will present their findings.
