Abstract

The Bjorken sum rule and R ratio are constructed to O(a4) in the Landau gauge in the three momentum subtraction schemes of Celmaster and Gonsalves where a=g2/(16π2). We aim to examine the issue of convergence for observables in the various schemes as well as to test ideas on whether using the discrepancy in different scheme values is a viable and more quantum field theoretic alternative to current ways of estimating the theory error on a measurable.
