aMUSE financed by the European Community

The Frascati National Laboratory of INFN leads for the second time an H2020-MSCA-RISE European project, whose goal is to promote international and intersectoral collaborations by means of secondments of personnel. The new project aMUSE (advanced Muon Campus in US and Europe Contribution), selected among the 408 proposals submitted to the European Commission, it is an advanced upgrade of MUSE, 2016–2019. The total funding is of 1.9 MEuro, with 800 kEuro reserved to INFN. The Project will coordinate the activities of about 80 researchers from twelve European research institutes and industries participating to the search for New Physics in the muon sector and to the design of a new generation muon accelerators in high-profile US laboratories (Fermilab, BNL, SLAC).

The project involves the two Fermilab Muon Campus Experiments: Muon (g-2) and Mu2e.

Muon (g-2), which is taking data since 2016, will provide a factor of four improvement in the precision of the anomalous magnetic moment of the muon and will shed light on the discrepancy between this measurement and the Standard Model predictions. Mu2e is devoted to the search of the Charged Lepton Flavour Violation (CLFV), with the goal of improving by four orders of magnitude the discover sensitivity for the conversion of a muon to an electron, not yet observed. The high intensity of the muon beam will allow to explore mass scales up to 104 TeV/c2. The Mu2e data taking is currently planned for 2023. aMUSE proposes an ambitious extension of the activities already foreseen for the Muon Campus: an R&D program for innovative detectors for the Mu2e upgrade (Mu2e-II, with 10 times larger beam intensity) and the design of a new beamline for CLFV searches based on muon decays (μ→eγ, μ→3e) as an alternative to Mu2e-II. aMUSE will also constitute a launch pad for a European-USA network for the development of muon beams for low (CLFV) and high (muon collider) energy frontiers.

Dr. Simona Giovannella, LNF senior researcher, has coordinated the drafting and the organization of the project, and will act as International Coordinator of the aMUSE consortium. Giovannella participates to the KLOE/KLOE-2 experiment at LNF since its inception and is an active member of the Mu2e experiment since 2010, where she covers several responsibility roles.
