Dark neutrinos and a three-portal connection to the standard model (2020)
Journal Article
Ballett, P., Hostert, M., & Pascoli, S. (2020). Dark neutrinos and a three-portal connection to the standard model. Physical Review D, 101(11), Article 115025. https://doi.org/10.1103/physrevd.101.115025

We introduce a dark neutrino sector which respects a hidden Uð1Þ0 gauge symmetry, subsequently broken by the vacuum expectation value of a dark scalar. The model is a self-consistent realization of an extended hidden sector that communicates with the... Read More about Dark neutrinos and a three-portal connection to the standard model.

Heavy nearly-sterile neutrinos are a common ingredient in extensions of the Standard Model which aim to explain neutrino masses, like for instance in Type I seesaw models, or one of its variants. If the scale of the new Heavy Neutral Leptons (HNLs) i... Read More about Heavy Neutral Leptons from low-scale seesaws at the DUNE Near Detector.

Novel leptophilic neutral currents can be tested at upcoming neutrino oscillation experiments using two complementary processes, neutrino trident production and neutrino-electron (ν − e) elastic scattering. Considering generic anomaly-free Uð1Þ exten... Read More about Z's in neutrino scattering at DUNE.

Neutrino masses from a dark neutrino sector below the electroweak scale (2019)
Journal Article

We consider a minimal extension of the Standard Model which advocates a dark neutrino sector charged under a hidden U(1)′. We show that neutrino masses can arise radiatively in this model. The observed values are compatible with a light dark sector b... Read More about Neutrino masses from a dark neutrino sector below the electroweak scale.

Neutrino trident scattering at near detectors (2019)
Journal Article

Neutrino trident scattering is a rare Standard Model process where a charged-lepton pair is produced in neutrino-nucleus scattering. To date, only the dimuon final-state has been observed, with around 100 total events, while the other channels are as... Read More about Neutrino trident scattering at near detectors.

Nearly-sterile neutrinos with masses in the MeV range and below would be produced in the beam of the Short-Baseline Neutrino (SBN) program at Fermilab. In this article, we study the potential for SBN to discover these particles through their subseque...

Precision neutrino experiments vs the Littlest Seesaw (2017)
Journal Article

We study to what extent upcoming precision neutrino oscillation experiments will be able to exclude one of the most predictive models of neutrino mass and mixing: the Littlest Seesaw. We show that this model provides a good fit to current data, predi... Read More about Precision neutrino experiments vs the Littlest Seesaw.

Mixing angle and phase correlations from A5 with generalized CP and their prospects for discovery (2015)

The observed leptonic mixing pattern could be explained by the presence of a discrete flavor symmetry broken into residual subgroups at low energies. In this scenario, a residual generalized charge parity (CP) symmetry allows the parameters of the Po...

Small discrete family symmetries such as S4, A4 or A5 may lead to simple leading-order predictions for the neutrino mixing matrix such as the bimaximal, tribimaximal or golden ratio mixing patterns, which may be brought into agreement with experiment...
