I am going to review some common loop computation techinques which we have used in our recent works, including using QGraf to generate the Feynman diagram and amplitutes, especially in those process involving gauge-links, e.g., gluon fragmentation functions into heavy quarkonium, and some our observations in the numerical computations using the Sector Decompostion method. I will also report some results in our recent works involving heavy qarkonium production and decay process, as well as gluon fragmentation function into heavy quarkoium within NRQCD framework.
