Leptogenesis in the Neutrino Option (2019)
Journal Article
Brivio, I., Moffat, K., Pascoli, S., Petcov, S., & Turner, J. (2019). Leptogenesis in the Neutrino Option. Journal of High Energy Physics, 2019(10), Article 59. https://doi.org/10.1007/jhep10%282019%29059

We examine the compatibility between the Neutrino Option, in which the electroweak scale is generated by PeV mass type I seesaw Majorana neutrinos, and leptogenesis. We find the Neutrino Option is consistent with resonant leptogenesis. Working within... Read More about Leptogenesis in the Neutrino Option.

Z's in neutrino scattering at DUNE (2019)
Journal Article
Ballett, P., Hostert, M., Pascoli, S., Perez-Gonzalez, Y. F., Tabrizi, Z., & Funchal, R. Z. (2019). Z's in neutrino scattering at DUNE. Physical Review D, 100(5), Article 055012. https://doi.org/10.1103/physrevd.100.055012

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.

Heavy neutrinos with dynamic jet vetoes: multilepton searches at √s = 14, 27, and 100 TeV (2019)
Journal Article
Pascoli, S., Ruiz, R., & Weiland, C. (2019). Heavy neutrinos with dynamic jet vetoes: multilepton searches at √s = 14, 27, and 100 TeV. Journal of High Energy Physics, 2019(6), Article 49. https://doi.org/10.1007/jhep06%282019%29049

Heavy neutrinos (N) remain one of most promising explanations for the ori-gin of neutrinos’ tiny masses and large mixing angles. In light of broad advances in un-derstanding and modeling of hadron collisions at large momentum transfers, we revisit th...

Neutrino masses from a dark neutrino sector below the electroweak scale (2019)
Journal Article
Ballett, P., Hostert, M., & Pascoli, S. (2019). Neutrino masses from a dark neutrino sector below the electroweak scale. Physical Review D, 99(9), Article 091701(R). https://doi.org/10.1103/physrevd.99.091701

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.

U(1) ′ mediated decays of heavy sterile neutrinos in MiniBooNE (2019)
Journal Article
Ballett, P., Pascoli, S., & Ross-Lonergan, M. (2019). U(1) ′ mediated decays of heavy sterile neutrinos in MiniBooNE. Physical Review D, 99(7), Article 071701(R). https://doi.org/10.1103/physrevd.99.071701

The MiniBooNE low-energy excess is a long-standing problem which has received further confirmation with a reanalysis using newly collected data, with the anomaly now at the 4.8σ level. In this paper we propose a novel explanation which advocates a lo... Read More about U(1) ′ mediated decays of heavy sterile neutrinos in MiniBooNE.

Leptogenesis from low energy CP violation (2019)
Journal Article
Moffat, K., Pascoli, S., Petcov, S., & Turner, J. (2019). Leptogenesis from low energy CP violation. Journal of High Energy Physics, 2019(3), Article 034. https://doi.org/10.1007/jhep03%282019%29034

We revisit the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix. We demonstrate the viability of thermal fla... Read More about Leptogenesis from low energy CP violation.

Leptogenesis via a varying Weinberg operator: a semi-classical approach (2019)
Journal Article
Pascoli, S., Turner, J., & Zhou, Y.-L. (2019). Leptogenesis via a varying Weinberg operator: a semi-classical approach. Chinese Physics C, 43(3), Article 033101. https://doi.org/10.1088/1674-1137/43/3/033101

In this paper, we introduce leptogenesis via a varying Weinberg operator from a semi-classical perspective. This mechanism is motivated by the breaking of an underlying symmetry which triggers a phase transition that causes the coupling of the Weinbe...

Neutrino trident scattering at near detectors (2019)
Journal Article
Ballett, P., Hostert, M., Pascoli, S., Perez-Gonzalez, Y. F., Tabrizi, Z., & Funchal, R. Z. (2019). Neutrino trident scattering at near detectors. Journal of High Energy Physics, 2019(1), Article 119. https://doi.org/10.1007/jhep01%282019%29119

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.
