Charged-Higgs collider signals with or without flavor

A charged Higgs boson is a clear signal for an extended Higgs sector, as, for example, predicted by supersymmetry. Squark mixing can significantly change the pattern of charged-Higgs production and most notably circumvent the chiral suppression for single Higgs production. We evaluate the CERN LHC discovery potential in the light of flavor physics, in the single-Higgs production channel and in association with a hard jet for small and moderate values of tanβ. Thoroughly examining current flavor constraints we find that nonminimal flavor structures can have a sizable impact but tend to predict moderate production rates. Nevertheless, charged-Higgs searches will probe flavor structures not accessible to rare kaon, bottom, or charm experiments and can invalidate the assumption of minimal flavor violation
