Charge-exchange reactions with pion and kaon beams in the NA64h experiment at CERN
Sergei N. Gninenko, Sergey Kuleshov, Valery E. Lyubovitskij +1
The paper presents calculations of charge‑exchange reaction cross sections for pion and kaon beams on nuclear targets, enabling searches for dark‑sector particles through invisible…
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 operat…
Probing millicharged particles with NA64 and LDMX
Sergei N. Gninenko, N. V. Krasnikov, Sergey Kuleshov +7
Millicharged particles emerge as compelling candidates in numerous theoretically well-motivated extensions of the Standard Model. These hypothetical particles, characterized by an…
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…
