Automated One-loop Computation in Quarkonium Process within NRQCD Framework

In last decades, it has been realized that the next-to-leading order corrections may become very important, and sometimes requisite, for some processes involving quarkoinum production or decay, e.g., e+e− → J/ψ + ηc and J/ψ → 3γ. In this article, we review some basic steps to perform automated one-l...
