We calculate the single-spin-dependent cross section formula for the D-meson production and the direct-photon production in the pp collision induced by the twist-3 triple-gluon correlation functions in the transversely polarized nucleon. We also present a model calculation for the asymmetries in comparison with the preliminary data given by RHIC, showing the impact of the correlation functions on the asymmetries.
