N1 - Funding Information:
We thank Howard Trottier for his help with testing M.N.’s automated perturbation theory code, in particular by checking our Asqtad vertices and propagators. This work was supported in part by the DOE under grant no. DE-FG02-91ER40677 and by the Junta de Andalucía [P05-FQM-437 and P06-TIC-02302]. The numerical calculations for this work were carried out on the Fermilab lattice QCD clusters, which are a computing resource of the USQCD collaboration and are funded by the DOE. We are grateful to the Fermilab Computing Divisions for operating and maintaining the clusters. Fermilab is operated by Fermi Research Alliance, LLC, under Contract No. DE-AC02-07CH11359 with the United States Department of Energy.

N2 - We present results of a perturbative matching calculation performed at one-loop for heavy-light currents. We use the Fermilab action for the heavy quarks, the Asqtad action for the light quarks, and an improved gluon action. We also present results for heavy-heavy currents with Fermilab heavy quarks and improved glue.
