“…Though all loop diagrams contain divergent integrals, it was proved that gauge theories are renormalizable [19,20,21,22,23]. To remove the divergence, it is necessary to renormalize the theory by rescaling the fields and redefining the masses and coupling constant.…”

All one-loop renormalization constants for Non-Abelian gauge theory are computed in details by using the symmetry-preserving Loop Regularization method proposed in [1,2]. The resulting renormalization constants are manifestly shown to satisfy Ward-Takahaski-Slavnov-Taylor identities, and lead to the well-known one loop β function for Non-Abelian gauge theory of QCD [3]. The loop regularization method is realized in the dimension of original field theories, it maintains not only symmetries but also divergent behaviors of original field theories with the introduction of two energy scales. Such two scales play the roles of characterizing and sliding energy scales as well as ultraviolet and infrared cutoff energy scales. An explicit Check of those identities provides a clear demonstration how the symmetry-preserving Loop Regularization method can consistently be applied to non-Abelian gauge theories.

“…Here we report our results on depth profiling of the microwave surface resistance (R S ), one of the most important transport properties of superconductors especially for accelerator cavities and mobile communication systems [16][17][18], for GdBCO CCs with the I C as high as 794 A cm −1 at 77 K [5]. We use an 8.5 GHz TE 011 -mode rutile resonator for measuring the R S of the specimens.…”

We study depth profiling of the microwave surface resistance (RS) of GdBa2Cu3O7−δ (GdBCO) coated conductors (CCs) grown using the reactive co-evaporation by deposition and reaction (RCE-DR) method, a method enabling extremely high deposition rate. GdBCO CCs with the critical current (IC) of more than 790 A cm−1 at 77 K in self-field are used for the study. The RS of the GdBCO CCs is measured at temperatures of 10–80 K using a 8.5 GHz TE011-mode rutile resonator, which is compared with that of YBa2Cu3O7−δ films and GdBCO films epitaxially grown on single crystal substrates. It turns out that there is significant inhomogeneity in the RS over the thickness of the GdBCO layer, with the RS value of the top part at 30 K being almost two times higher than the corresponding one of the bottom part. A transmission electron microscopy study reveals that Gd2O3 grains coexist with GdBCO grains with the average Gd2O3 grain sizes being ∼150 nm at the top and ∼100 nm at the bottom of the GdBCO layer. We relate the inhomogeneity in the RS of the GdBCO layer with the positional dependence of the Gd2O3 grain size, for which effects of the dielectric losses from the Gd2O3 grains on the measured RS of the GdBCO layer are considered. Our results imply that the critical current density, another important transport property of superconductors, could be inhomogeneous over the thickness of the GdBCO layer grown using the RCE-DR method.
