Convergent perturbative nuclear effective field theory
Koji Harada, Hirofumi Kubo, Tatsuya Sakaeda +1
We consider the nuclear effective field theory including pions in the two-nucleon sector in the S waves up to including the next-to-next-to-leading order (NNLO) terms according to…
Wilsonian renormalization group analysis of nonrelativistic three-body systems without introducing dimerons
Koji Harada, Hirofumi Kubo, Issei Yoshimoto
Low-energy effective field theory describing a nonrelativistic three-body system is analyzed in the Wilsonian renormalization group (RG) method. No effective auxiliary field (dimer…
Pions are neither perturbative nor nonperturbative: Wilsonian renormalization group analysis of nuclear effective field theory including pions
Koji Harada, Hirofumi Kubo, Yuki Yamamoto
Pionful nuclear effective field theory (NEFT) in the two-nucleon sector is examined from the Wilsonian renormalization group point of view. The pion exchange is cut off at the floa…
Vacuum Structures of Supersymmetric Noncompact Gauge Theory
Kenzo Inoue, Hirofumi Kubo, Naoki Yamatsu
We consider models with a noncompact symmetry in the framework of supersymmetry. Contrary to the conventional approach, the noncompact symmetry is realized linearly…
Apparently noninvariant terms of nonlinear sigma model in the one-loop approximation
Koji Harada, Hirofumi Kubo, Yuki Yamamoto
We show how the Apparently Noninvariant Terms (ANTs), which emerge in perturbation theory of nonlinear sigma models, are consistent with the nonlinearly realized symmetry by employ…
Apparently non-invariant terms of nonlinear sigma models in lattice perturbation theory
Koji Harada, Nozomu Hattori, Hirofumi Kubo +1
Apparently non-invariant terms (ANTs) which appear in loop diagrams for nonlinear sigma models (NLSs) are revisited in lattice perturbation theory. The calculations have been done…
