Flavoured resonant leptogenesis at sub-TeV scales (2021)
Journal Article
Granelli, A., Moffat, K., & Petcov, S. (2021). Flavoured resonant leptogenesis at sub-TeV scales. Nuclear Physics B, 973, https://doi.org/10.1016/j.nuclphysb.2021.115597

We consider sub-TeV scale flavoured resonant leptogenesis within the minimal type-I seesaw scenario with two right-handed singlet neutrinos N1,2forming a pseudo-Dirac pair, concentrating on the case of masses of the pseudo-Dirac pair having values M1...

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.

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.

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.
