Abstract：

QCD predicts that the hadron mass comes from not only the quark through the Higgs coupling, but also the massless gluon through the trace anomaly of QCD energy momentum tensor. It is a highly non-trivial prediction since the gluon trace anomaly matrix element will be different by an order of magnitude in the pion and nucleon. I will show our present progress on the lattice QCD calculation of the trace anomaly, and some non-trivial observations.
