Leptonic signatures of doubly charged Higgs boson production at the LHC

Understand

The production of doubly charged Higgs bosons (H^{\pm\pm}) at the CERN LHC can give rise to distinctive multi-lepton signatures.

• The discovery potential of H^{\pm\pm} can be optimized by considering a search strategy which is sensitive to both of the dominant production mechanisms, q\bar q\to H^{++}H^{--} and q\bar {q'}\to H^{\pm\pm}H^{\mp}.
• We compare the discovery potential for the signatures of exactly four leptons and at least three leptons in the final state, using the same set of cuts.
• We have carried out fast detector simulations at the LHC for both signal and backgrounds for a wide range of values of the charged Higgs mass.
