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…
Proof of principle for a light dark matter search with low-energy positron beams at NA64
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
Thermal light dark matter (LDM) with particle masses in the 1 MeV - 1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Univers…
Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +49
Since its approval in 2016, NA64 has pioneered light dark matter (LDM) searches with electron, positron, muon, and hadron beams. The experiment has successfully met its primary obj…
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…
Measurement of the hard exclusive muoproduction cross section at COMPASS
G. D. Alexeev, M. G. Alexeev, C. Alice +169
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality…
Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target
G. D. Alexeev, M. G. Alexeev, C. Alice +166
The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable , th…
