Determination of light quark masses from the electromagnetic splitting of pseudoscalar meson masses computed with two flavors of domain wall fermions
Thomas Blum, Takumi Doi, Masashi Hayakawa +2
We determine the light quark masses from lattice QCD simulations incorporating the electromagnetic interaction of valence quarks. The meson masses are calculated on lattice QCD con…
Five-quark picture of Lambda(1405) in anisotropic lattice QCD
Noriyoshi Ishii, Takumi Doi, Makoto Oka +1
Five-quark (5Q) picture of Lambda(1405) is studied using quenched lattice QCD with an exotic 5Q operator of N\bar{K} type. To discreminate mere N\bar{K} and Σπscattering states, Hy…
The vector-scalar mixing in nuclear medium and the two quark component of scalar meson from QCD sum rules
Su Houng Lee, Takumi Doi
We derive the QCD sum rules for the vector and scalar meson mixing in nuclear medium, using a two quark interpolating field for both mesons. Modeling the mixing via a nucleon hole…
Theoretical Status of Pentaquarks
Takumi Doi
We review the current status of the theoretical pentaquark search from the direct QCD calculation. The works from the QCD sum rule and the lattice QCD in the literature are careful…
J/Ψat high temperatures in anisotropic lattice QCD
Hideaki Iida, Takumi Doi, Noriyoshi Ishii +1
J/Ψand η_c above the QCD critical temperature T_c are studied in anisotropic quenched lattice QCD, considering whether the c\bar c systems above T_c are compact quasi-bound states…
