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…
Implications of under Rank-One Flavor Violation hypothesis
David Marzocca, Marco Nardecchia, Alfredo Stanzione +1
We study the implications of the observed excess in under the assumption of Rank-One Flavour Violation, i.e. that New Physics couples to a single specific dire…
Closing in on new chiral leptons at the LHC
Daniele Barducci, Luca Di Luzio, Marco Nardecchia +1
We study the phenomenological viability of chiral extensions of the Standard Model, with new chiral fermions acquiring their mass through interactions with a single Higgs. We exami…
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…
Light vectors coupled to anomalous currents with harmless Wess-Zumino terms
Luca Di Luzio, Marco Nardecchia, Claudio Toni
We reconsider the case of light vectors coupled to anomalous fermionic currents, focussing on the interplay between UV and IR dynamics. Taking as a general framework the gauging of…
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…
