Nested Disappearing-Track plus Displaced-Vertex Topology at the HL-LHC: A Dual Long-Lived-Particle Signature of the Scotogenic Model

Renjie Wang

The scotogenic model generates sub-eV neutrino masses radiatively through small Yukawa couplings $\sim \mathcal{O}(10^{-3})$ that also set the decay length of the heavy neutral ferm…
