Description
The goal of the MUonE experiment at CERN is to help clarify the current picture of results concerning the anomalous magnetic moment of the muon, where tensions remain among Standard Model predictions based on different methods and inputs. The method is based on the precision measurement of the differential cross section of elastic μe scattering, obtained using the CERN SPS M2 muon beam, which delivers high‑intensity 160 GeV muons onto fixed targets made of light materials. The project has evolved over the past years through phases of increasing complexity. In the summer of 2025, a pilot run (Phase‑1) was carried out over two months of data taking, using a reduced but fully functional version of the detector. This setup consisted of three tracking stations, an electromagnetic calorimeter, a muon detector, a timing detector for measuring the muon arrival time, and a momentum spectrometer installed in the beamline upstream of the apparatus. The detectors were integrated into a new DAQ system performing event building and online selection on FPGAs at a frequency of 40 MHz. The results of the pilot run will be discussed, presenting preliminary findings on detector performance and future prospects.
