The Light Quark Masses from Lattice Gauge Theory

Brian J. Gough, George M. Hockney, Aida X. El-Khadra +5

We investigate the masses of the light quarks with lattice QCD. We show that most of the large dependence on the lattice spacing, a, observed in previous determinations using Wilso…

Light Quark Masses with an O(a)-Improved Action

T. Onogi, A. X. El-Khadra, B. J. Gough +5

We present the recent Fermilab calculations of the masses of the light quarks, using tadpole-improved Sheikholeslami-Wohlert (SW) quarks. Various sources of systematic errors are s…

Effects of Improvement: $f_{π}$ and $m_{q}$

Brian Gough, Tetsuya Onogi, Jim Simone

We present a study of the effects of improvement on light-quark physics using the Fermilab formalism. The calculations were performed at three different lattice spacings, with the…

Form Factors for B -> pi l nu-bar_l and B -> K* gamma Decays on the Lattice

UKQCD Collaboration, D. R. Burford, H. D. Duong +5

We present a unified method for analysing form factors in B -> pi l nu-bar_l and B -> K* gamma decays. The analysis provides consistency checks on the q^2 and 1/M extrapolations ne…

Probing with Penguins: A lattice calculation of the branching ratio for some of the exclusive modes of $b \to s γ$

K. C. Bowler

We calculate the leading-order matrix element for exclusive decays of $b \to s γ$ in the quenched approximation of lattice QCD on a $2 4^{3} \times 48$ lattice at $β = 6.2$ , using an O(a)-…

$B \to K^{*} γ$ : Penguins on the Lattice

UKQCD Collaboration

We calculate the leading-order matrix element for the decay $B \to K^{*} γ$ in the quenched approximation of lattice QCD on a $2 4^{3} \times 48$ lattice at $β = 6.2$ , using an O(a)-impro…
