摘要：We present a new (and general) algorithm for deriving lattice Feynman rules which is capable
of handling actions as complex as the Highly Improved Staggered Quark (HISQ) action. This
enables us to perform a perturbative calculation of the influence of dynamical HISQ fermions
on the perturbative improvement of the gluonic action in the same way as we have previously
done for asqtad fermions. We find the fermionic contributions to the radiative corrections in the
Lüscher-Weisz gauge action to be somewhat larger for HISQ fermions than for asqtad.
