Three-flavored nonresonant leptogenesis at intermediate scales (2018)
Journal Article
Moffat, K., Pascoli, S., Petcov, S., Schulz, H., & Turner, J. (2018). Three-flavored nonresonant leptogenesis at intermediate scales. Physical Review D, 98(1), Article 015036. https://doi.org/10.1103/physrevd.98.015036

Leptogenesis can successfully explain the matter-antimatter asymmetry via out-of-equilibrium decays of heavy Majorana neutrinos in the early Universe. In this article, we focus on nonresonant thermal leptogenesis and the possibility of lowering its s... Read More about Three-flavored nonresonant leptogenesis at intermediate scales.

Dark matter-neutrino interactions through the lens of their cosmological implications (2018)
Journal Article
Olivares-Del Campo, A., Bœhm, C., Palomares-Ruiz, S., & Pascoli, S. (2018). Dark matter-neutrino interactions through the lens of their cosmological implications. Physical Review D, 97(7), Article 075039. https://doi.org/10.1103/physrevd.97.075039

Dark matter and neutrinos provide the two most compelling pieces of evidence for new physics beyond the Standard Model of particle physics, but they are often treated as two different sectors. The aim of this paper is to determine whether there are v... Read More about Dark matter-neutrino interactions through the lens of their cosmological implications.

A new smooth-k space filter approach to calculate halo abundances (2018)
Journal Article
Leo, M., Baugh, C. M., Li, B., & Pascoli, S. (2018). A new smooth-k space filter approach to calculate halo abundances. Journal of Cosmology and Astroparticle Physics, 2018(04), Article 010. https://doi.org/10.1088/1475-7516/2018/04/010

We propose a new filter, a smooth-k space filter, to use in the Press-Schechter approach to model the dark matter halo mass function which overcomes shortcomings of other filters. We test this against the mass function measured in N-body simulations.... Read More about A new smooth-k space filter approach to calculate halo abundances.

Baryogenesis via leptonic CP-violating phase transition (2018)
Journal Article
Pascoli, S., Turner, J., & Zhou, Y. (2018). Baryogenesis via leptonic CP-violating phase transition. Physics Letters B, 780, 313-318. https://doi.org/10.1016/j.physletb.2018.03.011

We propose a new mechanism to generate a lepton asymmetry based on the vacuum CP-violating phase transition (CPPT). This approach differs from classical thermal leptogenesis as a specific seesaw model, and its UV completion, need not be specified. Th...

The effect of thermal velocities on structure formation in N-body simulations of warm dark matter (2017)
Journal Article

We investigate the impact of thermal velocities in N-body simulations of structure formation in warm dark matter models. Adopting the commonly used approach of adding thermal velocities, randomly selected from a Fermi-Dirac distribution, to the gravi...

Long-baseline neutrino oscillation experiments, in particular the Deep Underground Neutrino Experiment (DUNE) and Tokai to Hyper-Kamiokande (T2HK), will lead the effort in the precision determination of the as yet unknown parameters of the leptonic m...

MeV-scale sterile neutrino decays at the Fermilab Short-Baseline Neutrino program (2017)
Journal Article

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.

Flavon-induced connections between lepton flavour mixing and charged lepton flavour violation processes (2016)
Journal Article

In leptonic flavour models with discrete flavour symmetries, couplings between flavons and leptons can result in special flavour structures after they gain vacuum expectation values. At the same time, they can also contribute to the other lepton-flav... Read More about Flavon-induced connections between lepton flavour mixing and charged lepton flavour violation processes.

The role of flavon cross couplings in leptonic flavour mixing (2016)

In models with discrete flavour symmetries, flavons are critical to realise specific flavour structures. Leptonic flavour mixing originates from the misalignment of flavon vacuum expectation values which respect different residual symmetries in the c...
