Hunting Hidden Particles at CERN

The projected sensitivity to dark photons, as mapped across mass and coupling strength, reveals that future experiments-including NA62Cortina with updated bremsstrahlung production, and potential rearrangements of existing NA62 detectors-offer complementary pathways to explore parameter space currently inaccessible, while sensitivity projections from experiments like DarkQuest, FASER, and LHCb are not displayed to maintain focus on the ECN3 landscape.

A new study details how relatively simple upgrades to the SPS at CERN could dramatically expand the search for feebly interacting particles beyond the Standard Model.
