Constraining New Physics models from observables in bottom-up EFT
Marco Ardu, Sacha Davidson, Stéphane Lavignac
Upcoming experiments will improve the sensitivity to processes by several orders of magnitude, and could observe lepton flavour-changing contact interactions for the first…
Constraining Non-Standard Interactions with Coherent Elastic Neutrino-Nucleus Scattering at the European Spallation Source
Sabya Sachi Chatterjee, Stéphane Lavignac, O. G. Miranda +1
The European Spallation Source (ESS), currently under construction in Sweden, will provide an intense pulsed neutrino flux allowing for high-statistics measurements of coherent ela…
Displaced Vertex signatures of a pseudo-Goldstone sterile neutrino
Stéphane Lavignac, Anibal D. Medina
Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Stan…
Flavor effects in leptogenesis
P. S. Bhupal Dev, Pasquale Di Bari, Bjorn Garbrecht +3
Flavor effects can have a significant impact on the final estimate of the lepton (and therefore baryon) asymmetry in scenarios of leptogenesis. It is therefore necessary to account…
Resurrecting the minimal renormalizable supersymmetric SU(5) model
Borut Bajc, Stéphane Lavignac, Timon Mede
It is a well-known fact that the minimal renormalizable supersymmetric SU(5) model is ruled out assuming superpartner masses of the order of a few TeV. Giving up this constraint an…
Flavour always matters in scalar triplet leptogenesis
Stéphane Lavignac, Benoît Schmauch
We present a flavour-covariant formalism for scalar triplet leptogenesis, which takes into account the effects of the different lepton flavours in a consistent way. Our main findin…
