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…
Probing Heavy Neutrino Magnetic Moments at the LHC using Long-Lived Particle Searches
Rebeca Beltrán, Patrick D. Bolton, Frank F. Deppisch +2
We explore long-lived particle (LLP) searches using non-pointing photons at the LHC as a probe for sterile-to-sterile and active-to-sterile transition magnetic dipole moments of st…
Heavy neutral leptons from kaons in effective field theory
Rebeca Beltrán, Julian Günther, Martin Hirsch +2
In the framework of the low-energy effective theory containing in addition to the Standard Model fields heavy neutral leptons (HNLs), we compute the decay rates of neutral and char…
Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
