Dirac vs. Majorana HNLs (and their oscillations) at SHiP

Inar Timiryasov

SHiP is a proposed high-intensity beam dump experiment set to operate at the CERN SPS. It is expected to have an unprecedented sensitivity to a variety of models containing feebly interacting particles, such as Heavy Neutral Leptons (HNLs). Two HNLs or mor ...

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, Valerie Fiona Domcke, Juraj Klaric

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 ...

Sensitivity of the SHiP experiment to Heavy Neutral Leptons

Aurelio Bay, Guido Haefeli, Lesya Shchutska, Elena Graverini, Maria Elena Stramaglia, Sun Hee Kim, Federico Leo Redi, Florian Maria Wurm, Mikhail Chapochnikov, Alexey Boyarsky, Oleg Ruchayskiy, Adriano Pastore, Nathalie Sophie Adeline Serra, Inar Timiryasov, Nikolaos Charitonidis, Jean-Loup Tastet, Ekaterina Kuznetsova, Johannes Richard Cornelis Geerit Kruis, Sargis Hakobyan, Erica Manfredi, Eirini Koukovini Platia

Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe an ...

Quasi-elastic neutrino reactions on carbon and lead nuclei

Soheyl Massoudi

We examine neutral-current quasi-elastic neutrino-nucleus reactions on C-12 and Pb-208 targets. We use the relativistic mean field theory approach to describe the nuclear dynamics. We compute the cross sections for the scattering of 150, 500 and 1000 MeV n ...

The bearable compositeness of leptons

Luca Vecchi

Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures. We then update the bounds from charg ...

Machine Learning in High Energy Physics Community White Paper

João Miguel das Neves Duarte, Siyuan Wang, Conor Thomas Fitzpatrick

Machine learning is an important applied research area in particle physics, beginning with applications to high-level physics analysis in the 1990s and 2000s, followed by an explosion of applications in particle and event identification and reconstruction ...
