Abstract | Heavy neutral leptons (HNLs) are introduced in extensions of the standard model (SM) of particle physics to explain the nonzero neutrino masses via the seesaw mechanism. They can also be a dark matter candidate, or provide a mechanism for the generation of the matter-antimatter asymmetry in the universe. At the CERN Large Hadron Collider (LHC), HNLs could be produced in proton-proton collisions through various processes. The ATLAS and CMS experiments have performed HNL searches covering a wide mass range from a few GeV to several TeV. Here, a selection of recent results is presented that are based on the full pp collisions data set at 13 TeV recorded during Run 2 of the LHC (2015-2018). |
