Updated E141 constraints on a long-lived vector boson
A. Celentano, A. Marini, L. Marsicano
Since its first observation by the ATOMKI experiment in 2018, the anomaly has attracted considerable interest within the dark sector community as it may indicate the exi…
Improved limits on a new in scenarios with the NA64 experiment at CERN
The NA64 Collaboration, Yu. M. Andreev, A. Antonov +53
Extensions of the Standard Model featuring an additional gauge symmetry provide a compelling framework linking the origin of neutrino masses to possible dark matter ca…
Design and characterization of the POKERINO prototype for the POKER/NA64 experiment at CERN
Andrei Antonov, Pietro Bisio, Mariangela Bondì +3
The NA64 experiment at CERN H4 beamline recently started a high-energy positron-beam program to search for light dark matter particles through a thick-target, missing-energy measur…
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…
