Analysis of short-distance current correlators using OPE
M. Tomii, G. Cossu, B. Fahy +3
We investigate the correlators of flavor non-singlet bilinear operators calculated on the lattice at short distances. In the continuum theory, non-perturbative effects are encoded…
On the axial symmetry at finite temperature
JLQCD Collaboration, Guido Cossu, Hidenori Fukaya +3
We study the anomaly in two-flavor lattice QCD at finite temperature with the Möbius domain-wall Dirac operator. We generate gauge configurations in the temperature range…
Extracting the meson mass from gluonic correlators in lattice QCD
JLQCD collaboration, H. Fukaya, G. Cossu +2
Calculation of the eta-prime meson mass is a notoriously difficult problem, as it requires evaluation of the disconnected diagram which is costly and noisy. In this work, we use a…
Violation of chirality of the Möbius domain-wall Dirac operator from the eigenmodes
JLQCD collaboration, Guido Cossu, Hidenori Fukaya +2
We investigate the effects of the violation of the Ginsparg-Wilson (GW) relation in the Möbius domain-wall fermion formulation on the lattice with finite fifth dimension. Using a d…
Renormalization of two-dimensional XQCD
Hidenori Fukaya, Ryo Yamamura
Recently, Kaplan proposed an interesting extension of QCD named Extended QCD or XQCD with bosonic auxiliary fields [1]. While its partition function is kept exactly the same as tha…
meson mass from topological charge density correlator in QCD
JLQCD collaboration, H. Fukaya, S. Aoki +4
The flavor-singlet component of the eta prime meson is related to the topological structure of the SU(3) gauge field through the chiral anomaly. We perform a 2+1-flavor lattice QCD…
