Abstract

We suggest a resonant c b → H⁺ production search, followed by bosonic H⁺ → W⁺ H weak decay at the Large Hadron Collider (LHC). In the general two-Higgs-doublet model (G2HDM) that has flavor-changing neutral Higgs couplings, H⁺ is resonantly produced via the top-charm ρ_tc V_tb coupling at tree level, while H⁺ → W⁺ H weak decay occurs within the exotic second doublet, leading eventually to same-sign dilepton signals. We perform a signal-to-background analysis at the 14 TeV LHC and show that discovery seems possible with LHC Run 2 data already at hand.
