The perturbative computation of the gradient flow coupling for the twisted Eguchi-Kawai model with the numerical stochastic perturbation theory
Hironori Takei, Ken-Ichi Ishikawa, Masanori Okawa
The gradient flow method is a renormalization scheme in which the gauge field is flowed by the diffusion equation. The gradient flow scheme has benefits that the observables compos…

Perturbative gradient flow coupling of the twisted Eguchi-Kawai model with the numerical stochastic perturbation theory
Ken-Ichi Ishikawa, Masanori Okawa, Hironori Takei
The gradient flow scheme has emerged as a prominent nonperturbative renormalization scheme on the lattice, where flow time is introduced to define the renormalization scale. In thi…
