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…
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…
Search for mirror hidden sector with neutral kaons at NA64
S. N. Gninenko, N. V. Krasnikov
Mirror matter from the dark hidden sector with the same particle content and gauge interactions as in the standard model is still an interesting candidate for dark matter. Several…
Probing leptophobic dark sector with a pseudoscalar portal in the NA64 experiment at CERN
Sergei N. Gninenko, Dmitry V. Kirpichnikov, Nikolai V. Krasnikov +3
We propose the possibility of discovering a light pseudoscalar particle , axion-like particle (ALP), interacting mainly with quarks using the electron and photon scattering reac…
