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…
Development and integration of the NA64-DTC automation controller for the CERN "DESY Table" motorized platform
A. Antonov, A. Celentano, A. Marini +1
We report on the development, construction, and integration of a remote automation controller \texttt{NA64-DTC} for the so-called ``DESY Table'' motorised platform widely used at C…
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…
50 GeV in, nothing out: a sensitive probe of invisible and decays with NA64h
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar and mesons in the NA64h experiment at the CERN SPS. Our n…
First constraints on the explanation of the muon anomaly from NA64- at CERN
Yu. M. Andreev, A. Antonov, D. Banerjee +58
The inclusion of an additional gauge symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this pa…
Development of the fully Geant4 compatible package for the simulation of Dark Matter in fixed target experiments
B. Banto Oberhauser, P. Bisio, A. Celentano +12
The search for new comparably light (well below the electroweak scale) feebly interacting particles is an exciting possibility to explain some mysterious phenomena in physics, amon…
