A vector portal between the Standard Model and the dark sector is a predictive and compelling framework for thermal dark matter. Through co-annihilations, models of inelastic dark matter (iDM) and inelastic Dirac dark matter (i2DM) can reproduce t... Read More about Constraining light thermal inelastic dark matter with NA64.

The present and future status of heavy neutral leptons (2023)
Journal Article
Abdullahi, A. M., Barham Alzás, P., Batell, B., Beacham, J., Boyarsky, A., Carbajal, S., …Yu, J. (2023). The present and future status of heavy neutral leptons. Journal of Physics G: Nuclear and Particle Physics, 50(2), Article 020501. https://doi.org/10.1088/1361-6471/ac98f9

The existence of nonzero neutrino masses points to the likely existence of multiple Standard Model neutral fermions. When such states are heavy enough that they cannot be produced in oscillations, they are referred to as heavy neutral leptons (HNLs)....

Higher order initial conditions with massive neutrinos (2022)
Journal Article
Elbers, W., Frenk, C. S., Jenkins, A., Li, B., & Pascoli, S. (2022). Higher order initial conditions with massive neutrinos. Monthly Notices of the Royal Astronomical Society, 516(3), https://doi.org/10.1093/mnras/stac2365

The discovery that neutrinos have mass has important consequences for cosmology. The main effect of massive neutrinos is to suppress the growth of cosmic structure on small scales. Such growth can be accurately modelled using cosmological N-body simu... Read More about Higher order initial conditions with massive neutrinos.

Confronting SO(10) GUTs with proton decay and gravitational waves (2021)
Journal Article
King, S. F., Pascoli, S., Zhou, Y., & Turner, J. (2021). Confronting SO(10) GUTs with proton decay and gravitational waves. Journal of High Energy Physics, 2021(10), Article 225 (2021). https://doi.org/10.1007/jhep10%282021%29225

Grand Unified Theories (GUT) predict proton decay as well as the formation of cosmic strings which can generate gravitational waves. We determine which non-supersymmetric SO(10) breaking chains provide gauge unification in addition to a gravitational...

An optimal non-linear method for simulating relic neutrinos (2021)
Journal Article

Cosmology places the strongest current limits on the sum of neutrino masses. Future observations will further improve the sensitivity and this will require accurate cosmological simulations to quantify possible systematic uncertainties and to make pr...

FASERν is a newly proposed detector whose main mission is to detect the neutrino flux from the collision of the proton beams at the ATLAS Interaction Point (IP) during the run III of the LHC in 2022–2024. We show that this detector can also test cert... Read More about Discovery potential of FASERν with contained vertex and through-going events.

Gravitational Waves and Proton Decay: Complementary Windows into Grand Unified Theories (2021)
Journal Article

Proton decay is a smoking gun signature of grand unified theories (GUTs). Searches by Super-Kamiokande have resulted in stringent limits on the GUT symmetry-breaking scale. The large-scale multipurpose neutrino experiments DUNE, Hyper-Kamiokande, and... Read More about Gravitational Waves and Proton Decay: Complementary Windows into Grand Unified Theories.

Unravelling the richness of dark sector by FASERν (2020)
Journal Article

Dark neutrinos and a three-portal connection to the standard model (2020)
Journal Article

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.
