What is the relationship between pQCD and NRQCD?
Is it that pQCD is for high energy/short-distance regime, e.g. quark gluon plasma? And NRQCD is for low energy/long-distance regime, e.g. quarkonium ?
And what is relation between heavy quark effective theory and pQCD and that between heavy quark effective theory and NRQCD ?
Thanks in advance.
