Prospects for the Search for a Doubly-Charged Higgs in the Left-Right Symmetric Model with ATLAS

We estimate the potential for observation at the LHC of a doubly charged Higgs boson, as predicted in Left-Right symmetric models. Single production by vector boson fusion, $W^{+}{W}^{+}\to {\mathrm{\Delta }}_{L,R}^{++}$ and pair production by the Drell-Yan process $q\bar{q}\to {\mathrm{\Delta }}_{L,R}^{++}{\mathrm{\Delta }}_{L,R}^{--}$ are considered. Various decay channels are investigated: dileptons, including pairs of $\tau$’s, as well as $WW$
