Quark-antiquark potential and Q2 duality

Keiji Igi, Ken Ichi Hikasa

Research output: Contribution to journalArticlepeer-review


A detailed study is made of Q2 duality for the bb system and the hypothetical heavy tt system using several potentials which include the perturbative QCD results for short distances. It turns out that the QCD corrections are essential in order that the sum rule holds. The Coulomb-type correction should not be neglected, and the gluonic correction to the leptonic width is also important.
