Long-lived particles within the dark sector: promising signatures for dark matter searches at LHC

16.02.2018 11:30 – 12:30

Many particle physics models for dark matter (DM) predict signatures at collider in the form of monojet. However, if the dark sector also contains long-lived particles (LLPs), less usual signatures can arise. In this talk I will discuss this possibility by considering two different models: the "pseudo-Dirac model", which predicts displaced vertices, and the "chromo-electric dipole model", which is characterized by composite states referred to as R-hadrons, by analogy to what happens in supersymmetry. In both cases, these unusual signatures can be complementary, or even competitive, with standard searches.
