We compute the Higgs plus two-quark and one-gluon amplitudes ( H→qq¯g ) and Higgs plus three-gluon amplitudes ( H→3g ) in the Higgs effective theory with a general class of operators. By changing the quadratic Casimir C F to C A , the maximally transcendental parts of the H→qq¯g amplitudes turn out to be equivalent to that of the H→3g amplitudes, which also coincide with the counterparts in =4 SYM. This generalizes the so-called maximal transcendentality principle to the Higgs amplitudes with external quark states, thus the full QCD theory. We further verify that the correspondence applies also to two-loop form factors of more general operators, in both QCD and scalar-YM theory. Another interesting relation is also observed between the planar H→qq¯g amplitudes and the minimal density form factors in =4 SYM.
