Reconciling axion quality with post-inflation cosmology
Luca Di Luzio, Samuele Di Valeriano, Marco Nardecchia +1
We address the axion quality/cosmology tension that often plagues QCD axion models in post-inflationary Peccei-Quinn (PQ) breaking scenarios. In the proposed framework, the PQ symm…
A framework for missing-energy searches with anomalous light vectors
Luca Di Luzio, Marco Nardecchia, Stefano Scacco +1
We study light spin-1 gauge bosons coupled to electroweak-anomalous currents. For generic charge assignments, anomaly cancellation requires new fermions (anomalons) that are chiral…
Gauged -lepton chiral currents and
Luca Di Luzio, Marco Nardecchia, Claudio Toni
We consider a class of theories with a gauge symmetry associated with leptonic chiral currents. The low-energy effective field theory includes a light spin- boson coupl…
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…
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…
