Searching for Doubly-Charged Higgs Bosons at Future Colliders

摘要

Doubly-charged Higgs bosons (Delta--/Delta++) appear in several extentions to the Standard Model and can be relatively light. We review the theoretical motivation for these states and present a study of the discovery reach in future runs of the Fermilab Tevatron for pair-produced doubly-charged Higgs bosons decaying to like-sign lepton pairs. We also comment on the discovery potential at other future colliders.
