SUSY Higgs boson flavor-changing neutral currents at the LHC

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, 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(pp→h→tc)≃10−3−10−2pb, as the most promising FCNC channel to be detected at the LHC.
