Title: Constraining renormalon effects in lattice determination of heavy quark mass

Abstract

The Borel summation technique of infrared renormalons is applied to the lattice determination of heavy-quark mass. With Borel summation a physical heavy-quark pole mass and binding energy of a heavy-light meson can be defined in a rigorous and calculable manner. A notable feature of the Borel summation, compared to the usual perturbative cancellation of IR renormalons, is an automatic scale isolation. The two approaches of handling renormalon divergence are compared in the B-meson as well as in an (imaginary) heavy-light meson with a mass much larger than the inverse of the lattice spacing.

  • We study Polyakov loop correlations and spatial Wilson loop at finite temperature in two-flavor QCD simulations with the RG-improved gluon action and the clover-improved Wilson quark action on a 16{sup 3}x4 lattice. From the line of constant physics at m{sub PS}/m{sub V}=0.65 and 0.80, we extract the heavy-quark free energies, the effective running coupling g{sub eff}(T) and the Debye screening mass m{sub D}(T) for various color channels of heavy quark-quark and quark-antiquark pairs above the critical temperature. The free energies are well approximated by the screened Coulomb form with the appropriate Casimir factors at high temperature. The magnitude and themore » temperature dependence of the Debye mass are compared to those of the next-to-leading-order thermal perturbation theory and to a phenomenological formula in terms of g{sub eff}(T). We make a comparison between our results with the Wilson quark action and the previous results with the staggered quark action. The spatial string tension is also studied in the high temperature phase and is compared to the next-to-next-leading-order prediction in an effective theory with dimensional reduction.« less
  • We study the operator product expansion of the plaquette (gluon condensate) and the self-energy of an infinitely heavy quark. We first compute their perturbative expansions to order α{sup 35} and α{sup 20}, respectively, in the lattice scheme. In both cases we reach the asymptotic regime where the renormalon behavior sets in. Subtracting the perturbative series, we obtain the leading non-perturbative corrections of their respective operator product expansions. In the first case we obtain the gluon condensate and in the second the binding energy of the heavy quark in the infinite mass limit. The results are fully consistent with the expectationsmore » from renormalons and the operator product expansion.« less
  • A new iterative procedure in fitting data is proposed which can properly correct small nonlinear effects. Applying this procedure to fit the Polyakov loop correlation functions previously obtained in lattice QCD simulations, we are able to eliminate the finite-size boundary effects and obtain the quark potential functions themselves, instead of just parameters for the potentials. The quality of the fits is improved significantly. The potential functions obtained at {beta}=6.0--6.2 scale in fine detail, providing important further support of the scaling. The improved estimates of the string tension satisfy the asymptotic scaling within 97%. In comparison with experiments, the obtained valuemore » {radical}{sigma} /{Lambda}{sub {ital L}}=79{plus minus}3 indicates {Lambda}{sub MS}=449{plus minus}17 MeV, where MS denotes the minimal subtraction scheme. The coupling constant {alpha}=0.43{plus minus}0.03 agrees very well with experiments, and is also in excellent agreement with the theoretical value {pi}/8=0.39, assuming that the long-distance behavior of QCD can be effectively described by the Neveu-Schwarz string theory.« less
  • Recent results from lattice QCD simulations provide a realistic picture, based upon first principles, of [Upsilon] physics. We combine these results with the experimentally measured mass of the [Upsilon] meson to obtain an accurate and reliable value for the [ital b] quark's pole mass. We use two different methods, each of which yields a mass consistent with [ital M][sub [ital b]]=5.0(2) GeV. This corresponds to a bare mass of [ital M][sub [ital b]][sup 0]=4.0(1) GeV in our lattice theory and an [bar M][bar S] mass of [ital M][sub [ital b]][sup [bar M][bar S]]([ital M][sub [ital b]])=4.0(1) GeV. ([bar M][bar S]more » denotes the modified minimal-subtraction scheme). We discuss the implications of this result for the [ital c]-quark mass.« less
  • We report on recent efforts to incorporate Lattice QCD data on the mixing of open-flavor mesons and heavy quarkonia states into quarkonium phenomenology. We investigate the implications of this data for decay widths and for the manifestation of open threshold effects in heavy quarkonium spectroscopy.
