A minimal set of top-Higgs anomalous couplings Aguilar Saavedra, Juan Antonio Higgs boson LHC (Large Hadron Collider) We use the equations of motion to simplify the general form of fermion-fermion-Higgs interactions generated by dimension-six gauge-invariant effective operators. After removing redundant operators it is found that the most general H f_i f_j vertex for off-shell fermions f_i, f_j and an off-shell Higgs boson only involves scalar and pseudo-scalar terms, without derivatives. Examples are presented for the Htt and Htq interactions, where q=u,c, giving the explicit expressions of the vertices in terms of gauge-invariant operators. The new operator equalities obtained here also reduce the number of operators relevant for the Ztq vertices, although the general form of these interactions is not simplified with respect to previous results. 2014-02-27T11:48:01Z 2014-02-27T11:48:01Z 2009 info:eu-repo/semantics/article Aguilar-Saavedra, J.A.
