The origin of neutrino mass has been a longstanding question in high energy particle physics. One possible solution arises through the seesaw mechanism if neutrinos have a Majorana mass term. The most conclusive proof of Majorana neutrinos may be their detection from direct production of heavy right-handed neutrinos at the LHC. Limits on the existence of heavy right-handed neutrinos are placed through two searches performed by the Compact Muon Solenoid Collaboration. Each search targets the final state containing two same-flavor leptons and two jets. While the first search targets the production of right-handed neutrinos through mixing with the Standard Model W boson, the second search focuses on right-handed neutrinos produced through a heavy right-handed W boson consistent with the left-right symmetric extension of the Standard Model.
