Abstract: Current searches for doubly charged Higgs bosons (${H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}$) at the Fermilab Tevatron are sensitive to single production of ${H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}$, although the pair production mechanism $q\overline{q}\ensuremath{\rightarrow}{H}^{++}{H}^{--}$ is assumed to be dominant. In the context of a Higgs Triplet Model we study the mechanism ${q}^{\ensuremath{'}}\overline{q}\ensuremath{\rightarrow}{H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}{H}^{\ensuremath{\mp}}$ at the Tevatron and CERN Large Hadron Collider, and show that its inclusion can significantly improve the search potential for ${H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}$. Moreover, assuming that the neutrino mass is generated solely by the triplet field Yukawa coupling to leptons, we compare the branching ratios of ${H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{l}^{\ifmmode\pm\else\textpm\fi{}}{l}^{\ifmmode\pm\else\textpm\fi{}}$ and ${H}^{\ifmmode\pm\else\textpm\fi{}\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{H}^{\ifmmode\pm\else\textpm\fi{}}{W}^{*}$ for the cases of a normal hierarchical, inverted hierarchical, and degenerate neutrino mass spectrum.
