`Sterile Neutrinos at the LHC' Abstract: One of the simplest extensions of the Standard Model to explain the non-zero neutrino masses is to introduce sterile neutrinos. In this talk, after a brief discussion of the model-building aspects, we will review the existing experimental constraints on the masses and mixing of these sterile neutrinos. We will then discuss their ongoing searches at the LHC and will conclude with some remarks on their future prospects.
