Non-relativistic bottonium in the physical vacuum of QCD. Mass of the 1P level
Description
The phenomenological analysis of b anti b quarkonium states is presented. Certain matrix elements of the nonrelativistic imaginary time propagator, contributed by S and P waves are calculated for a heavy quarkonium. Effects of interaction of the quarkonium with nonperturbative fluctuations of the gluonic field in the physical vacuum of QCD are taken into account as well as those due to the short-distance Coulomb like gluon exchange. The results for the S wave are found to be in agreement with the data on γ and γ' resonances. It is shown that the γ(9.46) mass is definitely below are bare quark threshold: 2msub(b)-Msub(γ)=130+-50 MeV. Mass of the 1P level is calculated: Msub(1P)-Msub(γ)=370+-30 MeV
