Exploring asymmetries in three-body cLFV lepton decays: probing CP violation in HNL extensions of the SM
Adrian Darricau, Jonathan Kriewald, Ana M. Teixeira
In extensions of the Standard Model with Majorana sterile fermions, additional Dirac and Majorana CP-violating phases can have a significant impact on charged lepton flavour violat…
Exploring asymmetries in three-body cLFV lepton decays: probing CP violation in HNL extensions of the SM
Adrian Darricau, Jonathan Kriewald, Ana M. Teixeira
In the context of Standard Model extensions via Majorana sterile fermions, the presence of additional CP violating phases (Dirac and Majorana) has been shown to be at source of imp…
High-energy cLFV at TRISTAN: HNL extensions of the Standard Model
J. Kriewald, E. Pinsard, A. M. Teixeira
Within the context of heavy neutral lepton (HNL) extensions of the Standard Model, we compute the cross-sections for scattering, as well as several an…
Heavy neutral lepton corrections to SM boson decays: lepton flavour universality violation in low-scale seesaw realisations
A. Abada, J. Kriewald, E. Pinsard +2
We study lepton flavour universality violation in SM boson decays in low-scale seesaw models of neutrino mass generation, also addressing other electroweak precision observables. W…
LFV Higgs and -boson decays: leptonic CPV phases and CP asymmetries
A. Abada, J. Kriewald, E. Pinsard +2
Heavy neutral leptons are motivated by several extensions of the Standard Model and their presence induces modifications in the lepton mixing matrix, including new Dirac and Majora…

Indirect searches for New Physics via flavour observables
Jonathan Kriewald
Precision measures of electroweak and flavour observables, at both low and high energies, are highly complementary to direct searches for New Physics at high-energy colliders. Desp…
The role of leptonic CPV phases in cLFV observables
J. Kriewald, A. Abada, A. M. Teixeira
In models where the Standard Model is extended by Majorana fermions, interference effects due to the presence of CP violating phases have been shown to play a crucial role in lepto…
Flavour and CP symmetries in the inverse seesaw
C. Hagedorn, J. Kriewald, J. Orloff +1
We consider an inverse seesaw mechanism of neutrino mass generation in which the Standard Model is extended by (heavy) sterile states, and endowed with a flavour symmetry $G_…

A. Abada, J. Kriewald, A. M. Teixeira
In extensions of the Standard Model by Majorana fermions, the presence of additional CP violating phases has been shown to play a crucial role in lepton number violating processes.…
