Simulations are made at three values of lattice spacing a=0.22,0.16,0.11 fm and four values of sea quark mass in the range m PS /m V ≈0.8-0.6. Our provisional estimate for the continuum values of the decay constants are f Bd =208(10)(29) MeV, f Bs =250(10)(35)( +8 -0 ) MeV, f Dd =225(14)(40) MeV, f Ds =267(13)(48)( +10 -0 ) MeV for N f =2 where the statistical and systematic errors are separately listed, and the third error for f Bs and f Ds shows the uncertainty of the determination of the strange quark mass. We also carry out a set of quenched simulations using the same action to make a direct examination of sea quark effects. Taking the ratio of results for N f =2 and N f =0, we obtain f N f =2 Bd /f N f =0 Bd =1.11(6),f N f =2 Bs /f N f =0 Bs =1.14(5),f N f =2 Dd /f N f =0 Dd =1.03(6),f N f =2 Ds /f N f =0 Ds =1.07(5).

抄録
内容記述タイプ Abstract
内容記述 We present a calculation of the B and D meson decay constants in lattice QCD with two (N f =2) flavors of light dynamical quarks, using an O(a)-improved Wilson action for both light and heavy quarks and a renormalization-group improved gauge action. Simulations are made at three values of lattice spacing a=0.22,0.16,0.11 fm and four values of sea quark mass in the range m PS /m V ≈0.8-0.6. Our provisional estimate for the continuum values of the decay constants are f Bd =208(10)(29) MeV, f Bs =250(10)(35)( +8 -0 ) MeV, f Dd =225(14)(40) MeV, f Ds =267(13)(48)( +10 -0 ) MeV for N f =2 where the statistical and systematic errors are separately listed, and the third error for f Bs and f Ds shows the uncertainty of the determination of the strange quark mass. We also carry out a set of quenched simulations using the same action to make a direct examination of sea quark effects. Taking the ratio of results for N f =2 and N f =0, we obtain f N f =2 Bd /f N f =0 Bd =1.11(6),f N f =2 Bs /f N f =0 Bs =1.14(5),f N f =2 Dd /f N f =0 Dd =1.03(6),f N f =2 Ds /f N f =0 Ds =1.07(5). They show a 10–15 % increase in the N f =2 results over those of N f =0 for the B meson decay constants, while evidence for such a trend is statistically less clear for the D meson decay constants.
