Abstract

We suggest a resonant cb¯→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 ρtcVtb 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.
