The present and future status of heavy neutral leptons

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

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 ...

Mapping the Viable Parameter Space for Testable Leptogenesis

Marco Drewes, Juraj Klaric, Yannis Georis

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 ...

Feebly-Interacting Particles:FIPs 2020 Workshop Report

Martin Bauer, Alexey Boyarsky, Oleg Ruchayskiy, Lesya Shchutska, Marco Drewes

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebl ...

MeV-scale seesaw and leptogenesis

Marco Drewes, Michele Lucente, Valerie Fiona Domcke

We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also by ...

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider

Marco Drewes, Jessica Prisciandaro, Matthieu Philippe Luther Marinangeli, Ennio Salvioni, Victor Coco, Manfredi Ronzani, Patrick Foldenauer, Yi Zhang, Federico Leo Redi, Marco Trovato, Ahmed Hammad, Jia Liu, Giorgia Rauco, Xiao Wang

Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far ...

On lepton number violation in heavy neutrino decays at colliders

Marco Drewes, Juraj Klaric

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 ...

Low-scale leptogenesis with three heavy neutrinos

Marco Drewes, Michele Lucente, Juraj Klaric, Valerie Fiona Domcke

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 ...

Neutrinoless double beta decay and low scale leptogenesis

Marco Drewes, Shintaro Eijima

The extension of the Standard Model by right handed neutrinos with masses in the GeV range can simultaneously explain the observed neutrino masses via the seesaw mechanism and the baryon asymmetry of the universe via leptogenesis. It has previously been cl ...

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (search for hidden particles) experiment is intended to hunt for new physics in the largely unexplored domain of very weakly interacting particles with masses below ...

Dark matter, baryogenesis and neutrino oscillations from right-handed neutrinos

Mikhail Chapochnikov, Laurent Canetti, Tibor Frossard, Marco Drewes

We show that, leaving aside accelerated cosmic expansion, all experimental data in high energy physics that are commonly agreed to require physics beyond the Standard Model can be explained when completing the model by three right-handed neutrinos that can ...

Sterile Neutrinos as the Origin of Dark and Baryonic Matter

Mikhail Chapochnikov, Laurent Canetti, Marco Drewes

We demonstrate for the first time that three sterile neutrinos alone can simultaneously explain neutrino oscillations, the observed dark matter, and the baryon asymmetry of the Universe without new physics above the Fermi scale. The key new point of our an ...

Matter and antimatter in the universe

Mikhail Chapochnikov, Laurent Canetti, Marco Drewes

We review observational evidence for a matter-antimatter asymmetry in the early universe, which leads to the remnant matter density we observe today. We also discuss bounds on the presence of antimatter in the present-day universe, including the possibilit ...
