Abstract

We construct the quark-antiquark chiral odd distribution amplitudes including twist-four mass contributions for tensor mesons. We also give quark-antiquark-gluon distribution amplitudes, where we calculate the input parameters with QCD sum rules. With the help of equations of motion, we determine the twist-three and twist-four distribution amplitudes including SU(3) breaking terms. We use QCD ...
