Heavy neutral leptons and top quarks in effective field theory
Rebeca Beltrán, Giovanna Cottin, Julian Günther +3
We study the phenomenology of heavy neutral leptons (HNLs) at the LHC in effective field theory, concentrating on operators with top quarks. Depending on the operator choice…

Long-lived particle phenomenology in one-loop neutrino mass models with dark matter
Carolina Arbeláez, Giovanna Cottin, Juan Carlos Helo +2
Neutrino masses and dark matter (DM) might have a common origin. The scotogenic model can be considered the proto-type model realizing this idea, but many other variants exist. In…
