Searches for doubly charged Higgs bosons with the ATLAS detector

Doubly charged Higgs bosons ($H^{\pm\pm}$) appear in several beyond the Standard Model extensions, aimed to explain the mechanism for neutrino mass generation. The $H^{\pm\pm}$ either decays into pairs of leptons or $W$ bosons being, in either case, of same sign. Two complementary searches are performed using the ATLAS detector, exploring the two stated $H^{\pm\pm}$ decay patterns. This contribution discusses the methodologies used in the two searches and, eventually, the results obtained from data collected by the ATLAS detector at a center-of-mass energy of $\sqrt{s}=13$ TeV.
