Lattice study of meson correlators in the epsilon-regime of two-flavor QCD
JLQCD Collaboration, H. Fukaya, S. Aoki +7
We calculate mesonic two-point functions in the epsilon-regime of two-flavor QCD on the lattice with exact chiral symmetry. We use gauge configurations of size 16^3 32 at the latti…
Finite-volume Correction to the Pion Decay Constant in the Epsilon-Regime
Poul H. Damgaard, Thomas DeGrand, Hidenori Fukaya
In the chiral limit of QCD, the pion decay constant F can be extracted from lattice gauge theory by means of a coupling to isospin chemical potential. Here we compute the leading c…
Theta vacuum physics from QCD at fixed topology
Sinya Aoki, Hidenori Fukaya, Shoji Hashimoto +1
We propose a method to obtain physical quantities in the theta vacuum from those at fixed topology, which are different by finite size effects. Extending the work by Brower et al.,…
Lattice simulation of 2+1 flavors of overlap light quarks
JLQCD collaboration, S. Hashimoto, S. Aoki +6
We report on the status of the dynamical overlap QCD simulation project by the JLQCD collaboration. After completing two-flavor QCD simulation on a 16^3x32 lattice at lattice spaci…
Pion form factor from all-to-all propagators of overlap quarks
JLQCD collaboration, T. Kaneko, H. Fukaya +5
We report on our calculation of the pion electromagnetic form factor with two-flavors of dynamical overlap quarks. Gauge configurations are generated using the Iwasaki gauge action…
Pion mass difference from vacuum polarization
JLQCD Collaboration, E. Shintani, H. Fukaya +5
We calculate the electromagnetic contribution to the pion mass difference, , in the chiral limit through the type vacuum polarization using Das-…

JLQCD Collaboration, N. Yamada, S. Aoki +6
We report on a calculation of with two-flavor dynamical overlap fermions on a lattice at fm. The results are compared with the PQChPT prediction…
Topological susceptibility in two-flavor lattice QCD with exact chiral symmetry
S. Aoki, T. W. Chiu, H. Fukaya +8
We determine the topological susceptibility in two-flavor QCD using the lattice simulations at a fixed topological sector. The topological charge density is unambiguously def…
Numerical results of two-dimensional N=(2,2) super Yang-Mills theory
Hidenori Fukaya, Issaku Kanamori, Hiroshi Suzuki +1
We report the results of a numerical simulation of a lattice formulation of the two-dimensional N=(2,2) super Yang-Mills theory proposed by Suzuki and Taniguchi. We measure the 1-p…
Partially quenched chiral perturbation theory in the epsilon-regime
Poul H. Damgaard, Hidenori Fukaya
We calculate meson correlators in the epsilon-regime within partially quenched chiral perturbation theory. The valence quark masses and sea quark masses can be chosen arbitrary and…
Finite volume QCD at fixed topological charge
Sinya Aoki, Hidenori Fukaya, Shoji Hashimoto +1
In finite volume the partition function of QCD with a given is a sum of different topological sectors with a weight primarily determined by the topological susceptibility. If a…
Two-flavor lattice QCD in the epsilon-regime and chiral Random Matrix Theory
JLQCD, TWQCD collaboration, : +10
The low-lying eigenvalue spectrum of the QCD Dirac operator in the epsilon-regime is expected to match with that of chiral Random Matrix Theory (ChRMT). We study this correspondenc…
The chiral limit in lattice QCD
Hidenori Fukaya
It has been a big challenge for lattice QCD to simulate dynamical quarks near the chiral limit. Theoretically, it is well-known that the naive chiral symmetry cannot be realized on…
Two-flavor lattice QCD simulation in the epsilon-regime with exact chiral symmetry
JLQCD collaboration, H. Fukaya, S. Aoki +9
We perform lattice simulations of two-flavor QCD using Neuberger's overlap fermion, with which the exact chiral symmetry is realized at finite lattice spacings. The epsilon-regime…
