Update of kaon semileptonic form factor using PACS10 configurations
Takeshi Yamazaki, Ken-ichi Ishikawa, Naruhito Ishizuka +4
We calculate the form factors for the kaon semileptonic decay process using the PACS10 configurations, whose physical volume is more than (10 fm) very close to the physical poi…
Tensor renormalization group study of (1+1)-dimensional O(3) nonlinear sigma model with and without finite chemical potential
Xiao Luo, Yoshinobu Kuramashi
We study (1+1)-dimensional O(3) nonlinear sigma model using the tensor renormalization group method with the infinite limit of the bond dimension . A…
Tensor renormalization group study of (1+1)-dimensional U(1) gauge-Higgs model at with Lüscher's admissibility condition
Shinichiro Akiyama, Yoshinobu Kuramashi
We investigate the phase structure of the (1+1)-dimensional U(1) gauge-Higgs model with a term, where the U(1) gauge action is constructed with Lüscher's admissibility conditio…
Quantum phase transition of (1+1)-dimensional O(3) nonlinear sigma model at finite density with tensor renormalization group
Xiao Luo, Yoshinobu Kuramashi
We study the quantum phase transition of the (1+1)-dimensional O(3) nonlinear sigma model at finite density using the tensor renormalization group method. This model suffers from t…
Discretization effects on nucleon root-mean-square radii from lattice QCD at the physical point
Ryutaro Tsuji, Yasumichi Aoki, Ken-Ichi Ishikawa +4
We present results for the axial-vector coupling and root-mean-square (RMS) radii of the nucleon obtained from 2+1 flavor lattice QCD at the physical point with a large spatial ext…
