The differential distributions in rapidity and angles of the secondary lepton\nin the associated production of the top quark pair and higgs boson in\nproton-proton collisions at the LHC are quite sensitive to the top-higgs\ncoupling. However, the effects of anomalous couplings of the most general t\nanti-t h interaction with operators of dimension-six that are clearly visible\nin the signal of the associated production of the top quark pair and higgs\nboson are to large extent obscured by the background sub-processes with the\nsame final state. This means that analyses of such effects, in addition to\nhigher order corrections that are usually calculated for the on-shell top\nquarks and higgs boson, should include their decays and possibly complete off\nresonance background contributions to the corresponding exclusive reactions.\n
