Query: A novel scheme for the wave function renormalization of the composite
  operators   We propose a novel renormalization scheme for the hadronic operators. The
renormalization factor of the operator in this scheme is normalized by the
correlation function at tree level in coordinate space. If we focus on the
pseudo scalar operator, then its renormalization factor is related to the mass
renormalization factor of the fermion through the partially conserved
axial-vector current (PCAC) relation. Using the renormalization factor for the
pseudo scalar operator in our scheme, we obtain the mass anomalous dimension of
the SU(3) gauge theory coupled to N_f=12 massless fundamental fermions, which
has an infrared fixed point (IRFP). The mass anomalous dimension at the IRFP is
estimated as gamma_m^*= 0.044_{-0.024}^{+0.025} (stat.)_{-0.032}^{+0.057}
(syst.).
