Perturbative matching of heavy-light currents at one-loop

Presenter: Aida El-Khadra — University of Illinois

A. El-Khadra, E. Gamiz, A. Kronfeld and M. Nobes,

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.
