Test of vector portal with dark fermions in the charge-exchange reactions in the NA64 experiment at CERN SPS
Sergei N. Gninenko, Dmitry V. Kirpichnikov, Sergey Kuleshov +2
We consider an experiment to search for dark sector particles in dark photon kinetic mixing model by analyze invisible and semi-invisible decays of neutral mesons , ,…
Probing invisible vector meson decay mode with hadronic beam in the NA64 experiment at SPS/CERN
Alexey S. Zhevlakov, Dmitry V. Kirpichnikov, Sergei N. Gninenko +2
We test a novel idea of using a beam in the fixed-target experiments to search for New Physics in the events with missing energy. Bounds for invisible vector meson decay…
Lepton flavor violating dark photon
Alexey S. Zhevlakov, Dmitry V. Kirpichnikov, Valery E. Lyubovitskij
We study possible impact of dark photons on lepton flavor phenomenology. We derive the constraints on non-diagonal dark photon couplings with leptons by analyzing corresponding con…
Measurement of the intrinsic hadronic contamination in the NA64 high-purity beam at CERN
Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +65
In this study, we present the measurement of the intrinsic hadronic contamination at the CERN SPS H4 beamline configured to transport electrons and positrons at 100 GeV/c momentum.…
