The decay as a QCD axion search: comparing reinterpretation approaches
Merna Abumusabh, Giulio Dujany, Diego Guadagnoli +2
Two recent independent analyses of Belle II data yield limits on -- the two-body mode to a light invisible particle su…
Constraints on a Light Leptophilic Scalar from Dark-Sector Couplings
Marco Graziani, Giacomo Landini, Federico Mescia +2
We study a minimal framework where a Majorana fermion dark matter particle interacts with a light scalar mediator coupled mainly to electrons. We examine both freeze-out and freeze…
On the Atomki nuclear anomaly after the MEG-II result
Daniele Barducci, Davide Germani, Marco Nardecchia +2
Recent experimental results from the Atomki collaboration have reported the observation of anomalous effects in Beryllium, Helium and Carbon nuclear transitions that could hint at…
Illuminating the dark: mono- signals at NA62
D. Barducci, E. Bertuzzo, M. Taoso +2
Dipole interactions between dark sector states or between a Standard Model particle and a dark state can efficiently be searched for via high-intensity fixed-target facilities. We…
