Rigourous QCD Evaluation of Spectrum and Other Properties of Heavy Quarkonium Systems; II Bottomium with n=2, l=0,1

We calculate the Lamb, fine and hyperfine shifts in \(b\bar b\) with \(n=2\), \(l=0,1\). Radiative corrections as well as leading nonperturbative corrections (known to be due to the gluon condensate) are taken into account. The calculation is parameter-free, as we take \(\Lambda\), \({\langle \alpha...
