From beam dumps to missing energy: the SPS search for hidden particles
For more than four decades, CERN’s Super Proton Synchrotron has served as a testing ground for new ways to search for particles that interact only feebly with ordinary matter. In a recent lecture, NA64 co-spokesperson Paolo Crivelli traced the evolution of this programme – from the first beam-dump experiments to missing-energy and missing-momentum searches, precision…

Closing the gap between beam dump and colliders ALPs searches with NA64
Closing the gap between beam dump and colliders ALPs searches with NA64 The axion was postulated to provide a solution to the “strong CP” problem. This pseudo-scalar particle emerges as a consequence of the breaking of the Peccei-Quinn (PQ) symmetry [1,2,3] (link to EP article on Axions). Typically, models of QCD axions predict a specific

Exploring dark sector with NA64: First results from the combined analysis of 2016-2018 runs
Exploring dark sector with NA64: First results from the combined analysis of 2016-2018 runs Searches for dark matter (DM) particles, an essential experimental goal for particle physics, are entering in an interesting stage. Despite the strong astrophysical evidence for dark matter, little is still known about the origin and dynamics of this substance of our

Exploring the dark sector with NA64
Exploring the dark sector with NA64 The field of dark matter (DM) particle physics is at an interesting stage, as key discoveries are anticipated. However, despite the intensive direct, indirect and LHC searches, the experiments have not yet yielded unambiguous Dark Matter (DM) signals. Though stringent constraints obtained on DM coupling to Standard Model (SM)
