Search for doubly charged Higgs boson production in multi-lepton final states using 139 fb - 1 of proton–proton collisions at √s = 13 TeV with the ATLAS detector

A search for pair production of doubly charged Higgs bosons (H-+/-+/-), each decaying into a pair of prompt, isolated, and highly energetic leptons with the same electric charge, is presented. The search uses a proton-proton collision data sample at a cen
