Physics Reports, 2008 Leptogenesis is a class of scenarios where the baryon asymmetry of the Universe is produced from a lepton asymmetry generated in the decays of a heavy sterile neutrino. We explain the motivation for leptogenesis. We review the basic mechanism, and describe subclasses of models.

Nuclear Physics B, 2023 We present a study of resonant leptogenesis in a radiative seesaw model. We consider the case where two quasi-degenerate right-handed neutrinos realize resonant leptogenesis, and the CP violation necessary to achieve leptogenesis occurs through the CP ...

Leptogenesis in the Neutrino Option
Journal of High Energy Physics, 2019 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 the

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 Very recently novel implementation of type‐II seesaw mechanism for neutrino mass has been proposed in SU(5) grand unified theory with a number of desirable new physical phenomena beyond the standard model. Introducing heavy right‐handed neutrinos and extra fermion singlets, in this work we show how the type‐I seesaw cancellation mechanism works in this

Leptogenesis from low energy CP violation
Journal of High Energy Physics, 2019 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.

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 The future long baseline experiments such as DUNE and T2HKK have promising prospects to determine the neutrino mass hierarchy and measuring standard CP phase δ. However, presence of possible nonstandard interactions of neutrinos with matter may intricate this picture and is the subject matter of the present work.

Long‐Baseline Oscillation Experiments as a Tool to Probe High Energy Flavor Symmetry Models
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We review the current status of neutrino oscillation experiments, mainly focusing on T2(H)K, NOνA, and DUNE. Their capability to probe high energy physics is found in the precision measurement of the CP phase and θ23. In general, neutrino mass models predict correlations among the mixing angles that can be used to scan and shrink their parameter space.

Neutrino Mass and the Higgs Portal Dark Matter in the ESSFSM
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We extend the standard model with three right‐handed singlet neutrinos and a real singlet scalar. We impose two Z2 and Z2′ symmetries. We explain the tiny neutrino mass‐squared differences with two Z2‐ and Z2′‐even right‐handed neutrinos using type I seesaw mechanism.

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Neutrino physics is a mature branch of science with all the three neutrino mixing angles and two mass squared differences determined with high precision. In spite of several experimental verifications of neutrino oscillations and precise measurements of two mass squared differences and the three mixing angles, the unitarity of the leptonic mixing ...
