    Abstract:

    We study infrared conformality of the twelve-flavor QCD on the lattice. Utilizing a HISQ type action which is useful to study the continuum physics, we analyze the lattice data of the mass and the decay constant of a pseudoscalar meson and the mass of a vector meson as well at several values of lattice spacing and fermion mass. Our result is consistent with the conformal hypothesis for the mass anomalous dimension γm ∼ 0.4 – 0.5.
