On Series and Integral Representations of Some NRQCD Master Integrals

We consider new ways of obtaining series and integral representations for master integrals arising in the process of matching of QCD to NRQCD. The latter results are exact in space-time dimension d. In addition, we discuss series expansion of the obtained results at fixed values of d.
