Searching for doubly-charged Higgs bosons at future colliders

摘要

Doubly-charged Higgs bosons ((Delta)(sup --)/(Delta)(sup ++)) appear in several extensions 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. 16 refs., 3 figs., 1 tab.
