One-loop mixing matrix of the N=1 SYM Supercurrent operator upon renormalization on the Lattice using stout-smeared Links
We extend the perturbative investigation of the renormalization and mixing patterns of the supercurrent operator in lattice ${\cal N}=1$ supersymmetric Yang-Mills (SYM) theory, using stout-smeared gauge links. We employ the SLiNC action for gluinos and a family of Symanzik improved gauge actions for gluons. Building upon previous studies employing clover-improved fermions and the Wilson gauge action, we compute the one-loop mixing matrix of the supercurrent operator among gauge-invariant and gauge-variant operators. Particular emphasis is placed on the structure of operator mixing in the presence of stout smearing parameters. Our results contribute toward refining fine-tuning strategies necessary for the restoration of supersymmetry in the continuum limit, and provide a stepping stone for future perturbative and nonperturbative investigations in supersymmetric theories on the lattice.
