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…
Prospects of boosted magnetic dipole inelastic fermion dark matter at ILC-BDX
I. V. Voronchikhin, D. V. Kirpichnikov
In this work, we investigate the projected sensitivity of the Beam-Dump eXperiment at the International Linear Collider (ILC-BDX) to inelastic fermionic dark matter coupled to the…
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…
Examining scalar portal inelastic dark matter with lepton fixed target experiments
I. V. Voronchikhin, D. V. Kirpichnikov
Inelastic dark matter scenarios have attracted considerable attention in contemporary particle physics. In this study, we investigate the phenomenology of sub-GeV inelastic dark ma…
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…
