The static Q\bar Q interaction at small distances and OPE violating terms
PACS: 11.15.Tk
Nonperturbative contribution to the one-gluon exchange produces a universal linear term in the static potential at small distances AV ~ 6Ncasar/2ir. Its role in the resolution of long-standing discrepancies in the fine splitting of heavy quarkonia and improved agreement with lattice data for static potentials is discussed, as well as implications for operator product expansion (OPE) violating terms in other processes.
