| 英文摘要 | We compute the Higgs plus two-quark and one-gluon amplitudes (H -> q (q) over barg) 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 -> q (q) over barg amplitudes turn out to be equivalent to that of the H -> 3g amplitudes, which also coincide with the counterparts in N = 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 -> q (q) over barg amplitudes and the minimal density form factors in N = 4 SYM. |
