We for the first time map the range of active-sterile neutrino mixing angles in which leptogenesis is possible in the type I seesaw model with three heavy neutrinos with Majorana masses between 50 MeV and 70 TeV, covering the entire experimentally accessib ...

Preheating in Palatini Higgs inflation on the lattice

Andrey Shkerin, Inar Timiryasov, Juraj Klaric, Adrien Florio

We study preheating following Higgs inflation in the Palatini formulation of gravity. We numerically evolve perturbations of the radial mode of the Higgs field and that of three scalars modeling the gauge bosons. We compare the two non-perturbative mechani ...

Low-scale leptogenesis with flavour and CP symmetries

Marco Drewes, Juraj Klaric, Yannis Georis

We consider a type-I seesaw framework endowed with a flavour symmetry, belonging to the series of non-abelian groups increment (3 n(2)) and increment (6 n(2)), and a CP symmetry. Breaking these symmetries in a non-trivial way results in the right-handed ne ...

The present and future status of heavy neutral leptons

Lesya Shchutska, Alexey Boyarsky, Oleg Ruchayskiy, Marco Drewes, Inar Timiryasov, Jean-Loup Tastet, Juraj Klaric

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). In th ...

Reconciling resonant leptogenesis and baryogenesis via neutrino oscillations

Inar Timiryasov, Juraj Klaric

Right-handed neutrinos offer an elegant solution to two well-established phenomena beyond the Standard Model (SM)-masses and oscillations of neutrinos, as well as the baryon asymmetry of the Universe. It is also a minimalistic solution, since it requires o ...

An allowed window for heavy neutral leptons below the kaon mass

Alexey Boyarsky, Oleg Ruchayskiy, Inar Timiryasov, Kyrylo Bondarenko, Juraj Klaric

The extension of the Standard Model with two gauge-singlet Majorana fermions can simultaneously explain two beyond-the-Standard-model phenomena: neutrino masses and oscillations, as well as the origin of the matter-antimatter asymmetry in the Universe. The ...

Uniting Low-Scale Leptogenesis Mechanisms

Inar Timiryasov, Juraj Klaric

In this Letter we demonstrate that what was previously considered as different mechanisms of baryon asymmetry generation involving two right-handed Majorana neutrinos with masses far below the Grand Unified Theory scale-leptogenesis via neutrino oscillatio ...

Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous studies invoking only two heavy neutrinos to the case of three heavy neutri ...

Springer2019

We study the perspective to observe lepton number violating signatures from heavy Majorana neutrino decays at colliders in view of the requirement to explain the light neutrino masses via the seesaw mechanism. In the minimal model with only two heavy neutr ...
