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…
Probing Hidden Leptonic Scalar Portals using the NA64 Experiment at CERN
A. Ponten, H. Sieber, B. Banto Oberhauser +7
In this study, we demonstrate the potential of the NA64 experiment at CERN SPS to search for New Physics processes involving transitions after the collision of 100…
Probing hidden sectors with a muon beam: implication of spin-0 dark matter mediators for muon anomaly and validity of the Weiszäcker-Williams approach
H. Sieber, D. V. Kirpichnikov, I. V. Voronchikhin +6
In addition to vector () type new particles extensively discussed previously, both CP-even () and CP-odd () spin-0 Dark Matter (DM) mediators can couple to muons and be pr…
Constraining Light Thermal Inelastic Dark Matter with NA64
Martina Mongillo, Asli Abdullahi, Benjamin Banto Oberhauser +5
A vector portal between the Standard Model and the dark sector is a predictive and compelling framework for thermal dark matter. Through co-annihilations, models of inelastic dark…
Probing Hidden Sectors with a muon beam: Total and differential cross-sections for vector boson production in muon bremsstrahlung
D. V. Kirpichnikov, H. Sieber, L. Molina Bueno +2
Vector bosons, such as Dark Photon or , can couple to muons and be produced in the bremsstrahlung reaction . Their possible subsequen…
