The $l=1$ Hyperfine Splitting in Bottomium as a Precise Probe of the QCD Vacuum

Phys.Lett. B351 (1995) 541-545 By relating fine and hyperfine spittings for l=1 states in bottomium we can factor out the less tractable part of the perturbative and nonperturbative effects. Reliable predictions for one of the fine splittings and the hyperfine splitting can then be made calculating...
