More on the infrared renormalon in $S U (N)$ QCD(adj.) on $R^{3} \times S^{1}$

Masahiro Ashie, Okuto Morikawa, Hiroshi Suzuki +1

We present additional observations to previous studies on the infrared (IR) renormalon in $S U (N)$ QCD(adj.), the $S U (N)$ gauge theory with $n_{W}$ -flavor adjoint Weyl fermions on~$\m…

Identification of perturbative ambiguity canceled against bion

Okuto Morikawa, Hiromasa Takaura

It was conjectured that bions, semi-classical objects found in a compactified spacetime, are responsible for the cancellation of the so-called renormalon ambiguities. Contrary to t…

Vacuum energy of the supersymmetric $C P^{N - 1}$ model on $R \times S^{1}$ in the $1/ N$ expansion

Kosuke Ishikawa, Okuto Morikawa, Kazuya Shibata +1

By employing the $1/ N$ expansion, we compute the vacuum energy~ $E (δ ε)$ of the two-dimensional supersymmetric (SUSY) $C P^{N - 1}$ model on~ $R \times S^{1}$ with $\mathb…

Renormalon structure in compactified spacetime

Kosuke Ishikawa, Okuto Morikawa, Kazuya Shibata +2

We point out that the location of renormalon singularities in theory on a circle-compactified spacetime $R^{d - 1} \times S^{1}$ (with a small radius $R Λ ≪ 1$ ) can differ fr…

Infrared renormalon in $S U (N)$ QCD(adj.) on $R^{3} \times S^{1}$

Masahiro Ashie, Okuto Morikawa, Hiroshi Suzuki +2

We study the infrared renormalon in the gluon condensate in the $S U (N)$ gauge theory with $n_{W}$ -flavor adjoint Weyl fermions (QCD(adj.)) on~ $R^{3} \times S^{1}$ with the $\math…

Numerical study of ADE-type $N = 2$ Landau--Ginzburg models

Okuto Morikawa

At an extremely low-energy scale, it is believed that the two-dimensional $N = 2$ Wess--Zumino model becomes an $N = 2$ superconformal field theory (SCFT). We study…
