First bounds on effective muon interactions using the NA64 experiment at CERN
Paolo Crivelli, Josu Hernandez-Garcia, Jacobo Lopez-Pavon +2
We analyze how NA64 can contribute to the global SMEFT program demonstrating that it can probe two effective four lepton operators completely unbounded so far and break one of…

High efficiency veto hadron calorimeter in the NA64 experiment at CERN
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +53
NA64 is a fixed-target experiment at the CERN SPS designed to search for Light particle Dark Matter (LDM) candidates with masses in the sub-GeV range. During the 2016-2022 runs, th…
