Status of R(s) measurements by energy scan method
Abstract
The precise low-energy e+e- → hadrons cross section are used in SM prediction of various fundamental quantities, like the anomalous magnetic moment of the muon. Direct energy scan experiments were always one of the main tool to provide this information. Status of R(s) measurements using this method is presented, some of the most recent results are discussed in details.
