Search for doubly charged Higgs bosons using the same-sign diboson mode at the LHC

Understand

Doubly charged Higgs bosons are predicted in many new physics models with an extended Higgs sector that contains a Higgs triplet field.

  • Current experimental searches have been focusing mainly on the scenario in which the same-sign dilepton decay modes are the dominant ones.
  • We study the scenario where the vacuum expectation value of the triplet field is sufficiently large so that the associated charged Higgs bosons decay dominantly to a pair of weak gauge bosons instead.
  • A detailed simulation of the signal and the backgrounds is performed for the CERN Large Hadron Collider at the collision energy of 8 TeV and 14 TeV.
