Discovering Heavy Neutral Leptons with the Higgs Boson
Nicolás Bernal, Kuldeep Deka, Marta Losada
We study the dominant signatures that arise in Higgs physics at colliders when extending the Standard Model (SM) with a Yukawa interaction to heavy neutral leptons (HNL), while sup…
The flavor of a light charged Higgs
Nicolás Bernal, Marta Losada, Yosef Nir +1
The ATLAS Collaboration has recently reported a search for light-charged Higgs in decay, with . An excess with a local significance of approximately $3…
Time Dependent CP-even and CP-odd Signatures of Scalar Ultra-light Dark Matter in Neutrino Oscillations
Marta Losada, Yosef Nir, Gilad Perez +2
Scalar ultra-light dark matter (ULDM) interacting with neutrinos can induce, under certain conditions, time-dependent modifications to neutrino oscillation probabilities. The limit…
Parametric resonance in neutrino oscillations induced by ultra-light dark matter and implications for KamLAND and JUNO
Marta Losada, Yosef Nir, Gilad Perez +2
If ultra-light dark matter (ULDM) exists and couples to neutrinos, the neutrino oscillation probability might be significantly altered by a parametric resonance. This resonance can…
Probing scalar dark matter oscillations with neutrino oscillations
Marta Losada, Yosef Nir, Gilad Perez +1
If ultra-light dark matter (ULDM) exists and couples to neutrinos, it can be discovered via time-periodic variations in the neutrino mass and mixing parameters. We analyze the curr…
Analytic Techniques for Solving the Transport Equations in Electroweak Baryogenesis
Elina Fuchs, Marta Losada, Yosef Nir +1
We develop an efficient method for solving transport equations, particularly in the context of electroweak baryogenesis. It provides fully-analytical results under mild approximati…
