Flavor-violating dark matter at MEG-II and Mu3e
Daniele Barducci, Giulio Marino, Paolo Panci +1
We investigate the potential of high-intensity muon experiments such as MEG~II and Mu3e to uncover dark matter (DM) through the lepton-flavor-violating decay . We…
Scalar Rayleigh Dark Matter: current bounds and future prospects
Daniele Barducci, Dario Buttazzo, Alessandro Dondarini +4
Dark Matter can interact with electroweak gauge bosons via higher-dimensional operators, in spite of being neutral under gauge interactions, much like neutral atoms interact with p…
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…
Neutrino dipole portal at a high energy collider
Daniele Barducci, Alessandro Dondarini
We study the phenomenology of dipole portal operators connecting active and sterile neutrinos at a futuristic muon collider. These operators can be the dominant portal betwee…
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…
