Description
The trace anomaly is one of the most non-trivial property of QCD which violates the scale invariance from the traceless QCD Energy momentum tensor, and then give non-zero mass to nucleon in the chiral limit. It has been predicted by QCD for over forty years, and will be verified by the EIC/EicC experiments in the near future.
I will present several procedures and the related lattice calculation of the trace anomaly contribution to the hadron mass, including pion and nucleon.
