The 1-loop correction of the QCD energy momentum tensor with the overlap   fermion and HYP smeared Iwasaki gluon
  We present the 1-loop renormalization of the energy momentum tensor using the overlap fermion and a HYP-smeared Iwasaki gauge action. We also calculate the 1-loop matching coefficient that convert the lattice simulation results renormalized in the RI/MOM scheme to the $\overline{\textrm{MS}}$ scheme. The dependence of the renormalization on the gauge action and the number of HYP smearing steps are also investigated.
