The sigma meson () at finite temperature with truncated overlap fermions
S. Date, Y. Murakami, M. Sekiguchi +2
We study the temperature dependence of meson screening masses in two-flavour lattice QCD using dynamical truncated overlap fermions, a type of lattice chiral fermions. The screenin…
Interglueball potential in lattice SU(N) gauge theories
Nodoka Yamanaka, Atsushi Nakamura, Masayuki Wakayama
The dynamics of the glueballs is important in the context of the experimental search as well as for understanding the non-Abelian gauge theory. The glueballs of the dark …
Spectroscopy of mesons from lattice QCD with the truncated overlap fermions
Masayuki Wakayama, Yuko Murakami, Atsushi Nakamura +2
We study the ground state and next radial excitation of the mesons from a quenched lattice QCD simulation with the truncated overlap fermions formalism based on domain wall f…
Interglueball potential in SU(N) lattice gauge theory
Nodoka Yamanaka, Hideaki Iida, Atsushi Nakamura +1
We report on our calculation of the interglueball potentials in SU(2), SU(3), and SU(4) lattice Yang-Mills theories using the indirect (so-called HAL QCD) method. We use the cluste…
Glueball scattering cross section in lattice SU(2) Yang-Mills theory
Nodoka Yamanaka, Hideaki Iida, Atsushi Nakamura +1
We calculate the scattering cross section between two glueballs in Yang-Mills theory on lattice at , and 2.5 using the indirect (HAL QCD) me…
Search of QCD phase transition points in the canonical approach of the NJL model
Masayuki Wakayama, Atsushi Hosaka
We study the Lee-Yang zeros in the canonical approach to search phase transition points at finite temperature and density in the Nambu-Jona-Lasinio (NJL) model as an effective mode…

Yuko Murakami, Shin Muroya, Atsushi Nakamura +4
We study the meson using a quenched lattice quantum chromodynamics simulation with the truncated overlap fermions formalism based on the domain wall fermions. The obtained li…
Lee-Yang zeros in lattice QCD for searching phase transition points
M. Wakayama, V. G. Bornyakov, D. L. Boyda +5
We report Lee-Yang zeros behavior at finite temperature and density. The quark number densities, <n>, are calculated at the pure imaginary chemical potential, where no sign problem…
Lattice QCD at finite baryon density using analytic continuation
V. G. Bornyakov, D. L. Boyda, V. A. Goy +6
We simulate lattice QCD with two flavors of Wilson fermions at imaginary baryon chemical potential. Results for the baryon number density computed in the confining and deconfining…
Chiral Symmetry and hadron properties at finite temperature -A numerical experiment
Teiji Kunihiro, Shin Muroya, Atsushi Nakamura +4
We study the hadron properties at finite temperature from measurement of the screening masses, using two-flavor full QCD of the hybrid Monte Carlo (HMC) algorithm with the renormal…
Lattice QCD study of four-quark components of the isosinglet scalar mesons: Significance of disconnected diagrams
Masayuki Wakayama, Teiji Kunihiro, Shin Muroya +4
We study the possible significance of four-quark states in the iso-singlet scalar mesons (, ) by performing two-flavor full lattice QCD simulations on an $8^3 \…
Analysis of the scalar mesons on the Lattice
Masayuki Wakayama, Chiho Nonaka
We study the possibility that the scalar mesons exist as four-quark states. The energy shift of two pseudoscalar mesons as a function of spatial lattice size makes a distinction be…
