Abstract: Many beyond the Standard Model theories introduce sterile neutrinos in order to provide solutions to several open problems in particle physics and cosmology. Among the different ways of probing their existence, searches for collider signatures with displaced vertices are particularly appealing due to their low SM backgrounds. Interestingly, sterile neutrinos of few GeV with mixings that are allowed by present constraints can lead to displaced vertices. We revisit the potential of the LHC for this kind of signatures, paying special attention to the role of flavor and different kinematic configurations.
