چکیده
A systematic study of a wide class of nonrelativistic models of bb quarkonia is described. It is found that the potential V (r) = 0.706380(√ r − 0.460442 r) + 8.81715 (all in GeV) with the b-quark mass m b = 4.80303 GeV gives a satisfactory description of the experimental data below the threshold for strong decays (χ 2 /DF = 6.5/7). Limitations and implications of this observation are discussed.

A model based on a nonrelativistic potential supplemented by spin dependent terms of the Breit-Fermi type is described. This model reproduces the known masses of the bb quarkonia within 1MeV and the known masses of the cc quarkonia within 5MeV. Many predictions are made, some of them, e.g. for the fine splittings of the high L states of the bb quarkonia and of the mass spectrum of the bc quarko...

A nonrelativistic Hamiltonian with plausible spin dependent corrections is proposed for the quarkonia below their respective strong decay thresholds. With only six free parameters this model reproduces the nine known masses of the bottomonia within about 1 MeV, the six known masses of the charmonia within a few MeV and the five known leptonic decay widths of the 3 S 1 states within about 20 %. ...

We consider a general scheme for calculating the leptonic constant of heavy quarkonium ¯ QQ in the framework of nonrelativistic quantum chromodynamics, NRQCD, operating as the effective theory of nonrelativistic heavy quarks. We explore the approach of statitic potential in QCD, which takes into account both the evolution of effective charge in the three-loop approximation and the linearly rais...

متن کاملA Systematic Study on Nonrelativistic Quarkonium Interaction
A recently proposed strictly phenomenological static quark-antiquark potential belonging to the generality V (r) = −Ar+κr+V0 is tested with heavy quarkonia in the context of the shifted large N-expansion method. This nonrelativistic potential model fits the spin-averaged mass spectra of the cc, bb and cb quarkonia within a few MeV and also the five experimentally known leptonic decay widths of ...
