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…
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…
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…
Probing the dipole portal to heavy neutral leptons via meson decays at the high-luminosity LHC
Daniele Barducci, Wei Liu, Arsenii Titov +2
We consider the dipole portal to sterile neutrinos, also called heavy neutral leptons (HNLs). The dipole interaction with the photon leads to HNL production in meson decays, as wel…
A boosted muon collider
Daniele Barducci, Alessandro Strumia
A muon collider could produce the heavier Standard Model particles with a boost, for example in resonant processes such as or . We propose machine config…
Perturbative unitarity constraints on generic vector interactions
Daniele Barducci, Marco Nardecchia, Claudio Toni
We study perturbative unitarity constraints on generic interactions between fermion and vector fields, which are allowed to have generic quantum numbers under a $\prod_i SU(N_i) \o…
An updated view on the ATOMKI nuclear anomalies
Daniele Barducci, Claudio Toni
In view of the latest experimental results recently released by the ATOMKI collaboration, we critically re-examine the possible theoretical interpretation of the observed anomalies…
Probing right-handed neutrinos dipole operators
Daniele Barducci, Enrico Bertuzzo, Marco Taoso +1
We consider the minimal see-saw extension of the Standard Model with two right-handed singlet fermions with mass at the GeV scale, augmented by an effective dipole operat…
QED Meson Description of the X17 and Other Anomalous Particles
Cheuk-Yin Wong
The X17 particle, the E38 particle, and the anomalous soft photons are anomalous particles because they do not appear to belong to any known Standard Model families. We propose a Q…
The see-saw portal at future Higgs factories: the role of dimension six operators
Daniele Barducci, Enrico Bertuzzo
We study an extension of the Standard Model with electroweak scale right-handed singlet fermions that induces neutrino masses, plus a generic new physics sector at a higher sca…
Perturbative unitarity constraints on generic Yukawa interactions
Lukas Allwicher, Pere Arnan, Daniele Barducci +1
We study perturbative unitarity constraints on generic Yukawa interactions where the involved fields have arbitrary quantum numbers under an group. W…
Dark Photon bounds in the dark EFT
Daniele Barducci, Enrico Bertuzzo, Giovanni Grilli di Cortona +1
Dark photons are massive abelian gauge bosons that interact with ordinary photons via a kinetic mixing with the hypercharge field strength tensor. This theory is probed by a variet…
Gravitational tests of electroweak relaxation
Daniele Barducci, Enrico Bertuzzo, Martín Arteaga Tupia
We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is gener…
