Automated Lattice Perturbation Theory and Decays of Heavy Quarkonia — •G.M. von Hippel1, R.R. Horgan1, and A.G. Hart21DAMTP, University of Cambridge, England — 2University of Edinburgh, Scotland

We present a method for the automated generation of vertices in perturbative Lattice QCD using a Python script, which due to its modular structure can easily be adapted for pure gauge theory, staggered fermions, or other fermionic actions, including NRQCD.

As an example, we show how to compute the matching coefficients for S-wave decays of heavy quarkonia between Lattice NRQCD and continuum QCD to Os v2) using our methods.
