Abstract For over 15 years, the “Radiative Corrections and Monte Carlo Generators for Low Energies” Working Group (Radio MonteCarLow WG) has been providing valuable support to the development of radiative corrections and Monte Carlo generators for low energy positron-electron data and tau-lepton decays. The Radio MonteCarLow WG held 20 meetings in which theorists and experimentalists, experts working in the field of positron-electron physics and partly also from the tau community, produced the higlhy-cited report “Quest for precision in hadronic cross sections at low energy: Monte Carlo tools vs. experimental data”. Recently, parts of the program have been included as a Joint Research Initiative in the group application of the European hadron physics community, STRONG2020, to the European Union. A specific goal of the working group is to create the annotated “PrecisionSM database” for low-energy hadronic cross sections in positron-electron collisions. The database will contain information about the reliability of the data sets, their systematic errors, and the treatment of Radiative Corrections. This proceeding reviews the results published by the Radio MonteCarLow WG and describes the status of the PrecisionSM database.
