Abstract

We compute and analyze the Flavor-Changing Neutral Current (FCNC) interactions of Minimal Supersymmetric Standard Model Higgs bosons ( h ≡ h0, H0, A0 ) with heavy quarks (top and bottom), focusing on the strongly-interacting sector. We correlate the Higgs bosons production cross-section at the LHC with the FCNC decay branching ratios and find the maximum allowed values of the production rates, σ ( p p → h → q q′ ) ≡ σ ( p p → h ) × B ( h → q q′ ) ( q q′ ≡ t c or b s ) after taking into account limits from low energy data on flavor-changing interactions. We single out the top quark channel, with a maximum production rate of σmax ( p p → h → t c ) ≃ 10-3 - 10-2 pb, as the most promising FCNC channel to be detected at the LHC. © 2006 Elsevier B.V.
