The topological charge is measured on gauge configurations generated with a renormalization group improved gauge action and a mean field improved clover quark action at three values of β=6/g 2 with four sea quark masses at each β. The lattice spacings at these β ’s are a≈0.22, 0.16 and 0.11 fm at the physical up and down quark mass, which are fixed by the physical ρ meson mass. The study is supplemented by simulations of pure SU(3) gauge theory with the same gauge action at 5 values of β with lattice spacings 0.09 fm≲a≲0.27 fm. We employ a field-theoretic definition of the topological charge together with cooling. For the topological susceptibility in the continuum limit of pure SU(3) gauge theory we obtain χ 1/4 t =197 +13 -16 MeV where the error shows statistical and systematic ones added in quadrature. In full QCD χ t at heavy sea quark masses is consistent with that of pure SU(3) gauge theory. A decrease of χ t toward light quark masses, as predicted by the anomalous Ward-Takahashi identity for U(1) chiral symmetry, becomes clearer for smaller lattice spacings. The cross over in the behavior of χ t from heavy to light sea quark masses is discussed.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者",
