RadioMonteCarLow 2 Phase I

RadioMonteCarLow 2 Phase I

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 pair, and electron pair, for scan and radiative-return experi...

Zusammenfassung: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 pair, and electron pair, for scan and radiative-return experiments. After discussing the various approaches that are used and effects that are included, we show differential cross sections obtained with AfkQed, BabaYaga@NLO, KKMC, MCGPJ, McMule, Phokhara, and Sherpa, for scenarios that are inspired by experiments providing input for the dispersive evaluation of the hadronic vacuum polarisation.
