Abstract
We briefly summarize some results obtained by potential NRQCD in the non perturbative regime: 1) a systematic procedure to obtain the heavy quarkonium potential in the 1/m expansion (with explicit expressions up to O(1/m^2) in terms of Wilson loops), and 2) a description of the heavy quarkonium inclusive decays to light particles, and of the NRQCD matrix elements (also the octet ones), in terms of the wave-function at the origen and some gluonic field-strength correlators.
