Neutrino physics at CERN

At CERN there has been recently a revival of neutrino physics. In 2018 a feasibility study was conducted which paved the way to the proposal of two neutrino experiments at the LHC, studying for the first time neutrinos with energies up to a few TeV. The FASER and SND@LHC experiments started their data taking with the Run3 of the LHC in 2022 and provided the first observation of collider neutrinos already one year after the start of data taking. This has set off the birth of a new era of collider neutrinos. In March 2024, CERN approved the construction of the Beam Dump Facility with the SHiP experiment to search for sterile neutrinos and to study all three neutrino flavours. SHiP will explore neutrino properties in an energy domain complementary to the LHC and will search for feebly interacting particles with unprecedented sensitivity as possible candidates to solve the open problems of the Standard Model.
