In the context of a recent CTEQ6.6 global analysis, we review a new technique for studying correlated theoretical uncertainties in hadronic observables associated with imperfect knowledge of parton distribution functions (PDFs). The technique is based on the computation of correlations between the predicted values of physical observables in the Hessian matrix method. It can be used, for example...

Pseudofermion methods for extracting all-point quark propagators are reviewed, with special emphasis on techniques for reducing or eliminating autocorrelations induced by low eigenmodes of the quark Dirac operator. Recent applications, including high statistics evaluations of hadronic current correlators and the pion form factor, are also described.

The joint extraction of m s and V us from hadronic τ decay data We discuss the simultaneous determination of ms and Vus from flavor-breaking hadronic τ decay sum rules, focussing on weight choices designed to better control problems associated with the slow convergence of the relevant integrated D = 2 OPE series. The results are found to display improved stability and consistency relative to th...
