Abstract

Abstract In certain new physics scenarios, a singly charged Higgs boson can couple to both fermions and W ± Z at tree level. We develop new strategies beyond current experimental searches using ppjjH ±, H ±tb at the Large Hadron Collider (LHC). With the effective H ± W Z and H ± tb couplings we perform a model-independent analysis at the collision energy $$ \sqrt{s}=13 $$ s = 13 TeV with the integrated luminosity of 3 ab−1. We derive the discovery prospects and exclusion limits for the charged Higgs boson in the mass range from 200 GeV to 1 TeV. With |F WZ |, |A t | ∼ 0.5–1.0 and 300 GeV ≲ $$ {m}_{H^{\pm }} $$ m H ± ≲ 400 GeV, we point out that a discovery significance of 5σ can be achieved. The constraints and projected sensitivities are also discussed in a realistic model, i.e., the modified Georgi-Machacek model without custodial symmetry. Our proposed search would provide direct evidence for a charged Higgs boson H ± that couples to W ± Z and tb, and has better sensitivity to the couplings of H ± W Z and H ± tb than current searches.
