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…

Precision continuous-wave laser measurement of the interval in positronium

Lucas de Sousa Borges, Edward Thorpe-Woods, Evans Javary +1

We report a 4.9\,ppb measurement of the positronium interval using continuous-wave two-photon laser spec…

Axion Searches at the CERN SPS: From Their Dawn to Current Prospects

Paolo Crivelli, Martina Mongillo

This mini-review traces the evolution of axion searches at the CERN Super Proton Synchrotron (SPS), beginning with the early proposal by Guido Barbiellini in 1982 and culminating i…

Two-Photon Optical Ramsey-Doppler Spectroscopy of Positronium and Muonium

Evans Javary, Edward Thorpe-Woods, Irene Cortinovis +3

Positronium and muonium, as purely leptonic atoms without internal structure, provide ideal systems for high-precision tests of quantum electrodynamics (QED) and measurements of fu…
