RUIZ Richard (IPPP, Durham)
Jet Vetoes and Heavy Neutrinos at Current and Future Hadron Colliders

(Interactions fondamentales, Astroparticules et Cosmologie)


Sommaire:

Heavy neutrinos that couple appreciably to Standard Model particles are a common prediction of low-scale neutrino mass models. If kinematically accessible, such hypothetical particles can be produced copiously at the Large Hadron Collider, and its potential successors, and shed light on the mysterious origin of tiny neutrino masses [1]. In this seminar, the results of a newly proposed search methodology for heavy neutrinos at hadron colliders are presented. The analysis proposal focuses on an unusual (but "safe" [2]) implementation of jet vetoes to separate signal from background. Nontrivial increases in sensitivity at the High-Luminosity LHC and potential successor hadron colliders are discussed.
