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…
On the internal inconsistency of the Wess-Zumino model
N. V. Krasnikov
We prove the internal inconsistency of the supersymmetric Wess-Zumino model. Our proof is based on three assumptions. The first assumption is that in the full theory the structure…
