Experimental Demonstration of Soft-Tissue Muon Scattering Tomography
Dipanwita Banerjee, Benjamin Banto Oberhauser, Paolo Crivelli +1
Muons have fascinated physicists since their discovery in cosmic rays almost a century ago. Their large mass and relatively long lifetime allow relativistic muons to traverse large…
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…
Feasibility of Low-Energy True Muonium Photoproduction
Ivo Schulthess, Benjamin Banto Oberhauser, Paolo Crivelli
True muonium, the bound state of a muon and an antimuon, is a theoretically well-understood but experimentally unobserved exotic atom. Its purely leptonic nature makes it a sensiti…
Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +49
Since its approval in 2016, NA64 has pioneered light dark matter (LDM) searches with electron, positron, muon, and hadron beams. The experiment has successfully met its primary obj…
Proof of principle for a light dark matter search with low-energy positron beams at NA64
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
Thermal light dark matter (LDM) with particle masses in the 1 MeV - 1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Univers…
Shedding light on Dark Sectors with high-energy muons at the NA64 experiment at the CERN SPS
Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +54
A search for Dark Sectors is performed using the unique M2 beam line at the CERN Super Proton Synchrotron. New particles () could be produced in the bremsstrahlung-like reaction…
50 GeV in, nothing out: a sensitive probe of invisible and decays with NA64h
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar and mesons in the NA64h experiment at the CERN SPS. Our n…
First constraints on the explanation of the muon anomaly from NA64- at CERN
Yu. M. Andreev, A. Antonov, D. Banerjee +58
The inclusion of an additional gauge symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this pa…
Exploration of the Muon and Light Dark Matter explanations in NA64 with the CERN SPS high energy muon beam
Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +54
We report on a search for a new () vector boson performed at the NA64 experiment employing a high energy muon beam and a missing energy-momentum technique. Muons from…
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.…
Search for a light muon-philic with the NA64- experiment at CERN
Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +58
The extension of Standard Model made by inclusion of additional gauge symmetry can explain the difference between the measured and the predicted value of the muon…
