Charge-exchange reactions with pion and kaon beams in the NA64h experiment at CERN

Sergei N. Gninenko, Sergey Kuleshov, Valery E. Lyubovitskij +1

We discuss a new approach to search for dark sector coupled to quarks in the invisible decays and oscillations of light neutral mesons produced in the charge-exchange (CEX) reactio…

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…

Missing energy signatures of inelastic magnetic dipole DM at NA64e

Sergei N. Gninenko, N. V. Krasnikov, I. V. Voronchikhin +1

Some extensions of the Standard Model consider inelastic dark matter (iDM) as an attractive candidate for sub-GeV DM of thermal origin that could be detected at modern accelerators…

Constraints on dark axion portal: missing energy and fermion EDMs

Sergei N. Gninenko, N. V. Krasnikov, Valery E. Lyubovitskij +4

We study a model in which a new interactions between the Standard Model (SM) photon and both the dark photon ( and an ALP () are described by the dark axion portal operato…

Performance of the front-end electronics of the CMS electromagnetic calorimeter barrel for the High-Luminosity LHC

The CMS Electromagnetic Calorimeter Group

The performance of the CMS electromagnetic calorimeter upgraded readout electronics, developed for the High-Luminosity phase of the LHC, is discussed. Data collected in two beam te…

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…
