A study of muon-electron elastic scattering in a test beam

In 2018, a test run with muons in the North Area at CERN was performed, running parasitically downstream of COMPASS spectrometer. The aim to investigate elastic interactions on atomic electrons, an experimental configuration similar one proposed by project MUonE, which plans perform very precise measurement differential cross-section interactions. taking data 190 GeV pion beam, stopped tungsten beam dump: from these pions decays passed through setup including graphite target followed 10 planes Si tracker and BGO crystal electromagnetic calorimeter placed end tracker. scattering events were analysed, compared expectations MonteCarlo simulation.
