abstract

We suggest searching for the charged Higgs boson at the Large Hadron Collider (LHC) via $cg \to b H^+ \to b t \bar b$. In the general two Higgs Doublet Model, extra top Yukawa couplings $\rho_{tc}$ and $\rho_{tt}$ can drive the disappearance of antimatter from the Universe, while $\bar cbH^+$ and $\bar tbH^+$ couple with strength $\rho_{tc}V_{tb}$ and $\rho_{tt}V_{tb}$, respectively. For $\rho_{tc},\, \rho_{tt} \sim 0.5$ and $m_{H^+} \sim 300$--500 GeV, evidence could emerge from LHC Run 2 data at hand, and discovery by adding Run 3 data in the near future.

  1. Dark Matter in the General 2HDM with Extra Top Yukawa Couplings

    hep-ph 2026-07 conditional novelty 5.0 of 10

    G2HDM plus a Z2-odd real scalar singlet yields viable top-window dark matter and six LHC benchmarks, including flavor-violating mono-top production of invisible H→SS.
