semileptonic decays in lattice QCD with domain-wall heavy quarks
T. Kaneko, Y. Aoki, B. Colquhoun +5
We calculate the form factors in 2+1 flavor relativistic lattice QCD by employing the Möbius domain-wall action for all quark flavors. Our simulations are ca…
2+1 flavor fine lattice simulation at finite temperature with domain-wall fermions
Sinya Aoki, Yasumichi Aoki, Hidenori Fukaya +4
Simulations for the thermodynamics of the 2+1 flavor QCD are performed employing chiral fermions. The use of Möbius domain-wall fermions with stout-link smearing is more effective…
A physicist-friendly reformulation of the Atiyah-Patodi-Singer index (on a lattice)
Hidenori Fukaya
The Atiyah-Singer index theorem on a closed manifold is well understood and appreciated in physics. On the other hand, the Atiyah-Patodi-Singer index, which is an extension to a ma…
Chiral fermion on curved domain-wall
Shoto Aoki, Hidenori Fukaya
We consider a massive fermion system having a curved domain-wall embedded in a square lattice. In a similar way to the conventional flat domain-wall fermion, chiral massless modes…
A physicist-friendly reformulation of the mod-two Atiyah-Patodi-Singer index
Hidenori Fukaya, Mikio Furuta, Yoshiyuki Matsuki +4
Gauge anomaly in 4-dimensions can be viewed as a current inflow into an extra-dimension, where the total phase of the fermion partition function is given in a gauge invariant way b…
FLAG Review 2021
Y. Aoki, T. Blum, G. Colangelo +34
We review lattice results related to pion, kaon, -meson, -meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communi…
What is chiral susceptibility probing?
JLQCD collaboration, S. Aoki, Y. Aoki +4
In the early days of QCD, the axial anomaly was considered as a trigger for the breaking of the symmetry through topological excitations of gluon fie…
Understanding the index theorems with massive fermions
Hidenori Fukaya
The index theorems relate the gauge field and metric on a manifold to the solution of the Dirac equation on it. In the standard approach, the Dirac operator must be massless in ord…
Role of axial U(1) anomaly in chiral susceptibility of QCD at high temperature
S. Aoki, Y. Aoki, H. Fukaya +3
The chiral susceptibility, or the first derivative of the chiral condensate with respect to the quark mass, is often used as a probe for the QCD phase transition since the chiral c…
