Abstract

The doubly charged Higgs boson (H±±) is a theoretical non-Standard Model scalar boson with both Drell-Yan and vector boson fusion production mechanisms. The dark photon (γd) is a theoretical dark matter non-SM gauge boson in the dark sector with Higgs and SUSY production mechanisms. We present our findings on triboson background events for doubly charged

Higgs bosons and dark photons in four-lepton final state event signatures

(l± l± l± l±l = e, μ). We analyze triboson behavior from PYTHIA models of

triple vector boson scatterings and their prevalent decay channels

(VVV → l± l± l± l±, V = W,Z). The triboson background events exhibit a

frequency that is relatively constant over increasing values of pT, displaying

a different behavior from the other sources of background. Our research provides insight into future, more efficient, pT background cuts in searches for dark photons and doubly charged Higgs bosons.
