Matching functions for heavy particles
S. D. Bass, R. J. Crewther, F. M. Steffens +1
We introduce matching functions as a means of summing heavy-quark logarithms to any order. Our analysis is based on Witten's approach, where heavy quarks are decoupled one at a tim…

Heavy-quark axial charges to non-leading order
S. D. Bass, R. J. Crewther, F. M. Steffens +1
We combine Witten's renormalization group with the matching conditions of Bernreuther and Wetzel to calculate at next-to-leading order the complete heavy-quark contribution to the…
