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 Sterile Neutrinos at the LHC in Effective Field Theory
Jordy de Vries, Herbert K. Dreiner, Julian Y. Günther +2
We study the prospects of a displaced-vertex search of sterile neutrinos at the Large Hadron Collider (LHC) in the framework of the neutrino-extended Standard Model Effective Field…

R-parity Violation and Light Neutralinos at ANUBIS and MAPP
Herbert K. Dreiner, Julian Y. Günther, Zeren Simon Wang
In R-parity-violating supersymmetry the lightest neutralino can be very light, even massless. For masses in the range MeV GeV the neutra…
