dc.description.abstract Using the recent four-loop calculations of the QCD p-function and the three-loop matching coefficients we study the induced errors in alpha(s)(m(Z)) obtained from alpha(s)(M-tau) due to the evolution procedure. We show that, when consistent matching and running is used at this order, these errors are pushed below 0.0005 in alpha(s)(m(Z)).
