Abstract
If the long-distance properties of pure gauge theories are described by thin strings, then quantum fluctuations induce a long-range spin-spin potential between widely separated heavy quarks. This potential falls off as the fifth power of the distance between the quarks and may be important in heavy-quark phenomenology.Keywords
