Doubly charged Higgs bosons and three-lepton signatures in the Higgs Triplet Model

Understand

Doubly charged Higgs bosons, H^{\pm\pm}, are being searched for in the Tevatron experiments.

• The most recent search by the D0 collaboration seeks three muons (mu^\pm\mu^\pm\mu^\mp), which are assumed to originate from the pair-production process, q\overline q\to H^{++}H^{--}, followed by the decay H^{\pm\pm} \to \mu^\pm \mu^\pm.
• In this three-lepton (3l) channel there are six distinct signatures for l=e or \mu.
• In the context of the Higgs Triplet Model, we quantify the dependence of the event numbers for the 3l channels on the parameters of the neutrino mass matrix.
