“…at the origin |ϕ n (0)| 2 , i.e., to the behaviour of the GE potential (or the vector coupling α st (r)) at small distances, not only in the AF region (r < ∼ 0.1 fm) but also in the region 0.1 fm < ∼ r < ∼ 0.3 fm, which in [39] called the intermediate region. This behavior is known quite well for the perturbative part, where Λ QCD is well known (for n f = 5 Λ For HL mesons with R > ∼ 0.6 fm this effect is becoming less important (for more discussion of the influence of the HF interaction see [51]).…”

Meson Green's functions and decay constants f Γ in different channels Γ are calculated using the Field Correlator Method. Both, spectrum and f Γ , appear to be expressed only through universal constants: the string tension σ, α s , and the pole quark masses. For the S-wave states the calculated masses agree with the experimental numbers within ±5 MeV. For the D and D s mesons the values of f P (1S) are equal to 210(10) and 260(10) MeV, respectively, and their ratio f Ds /f D =1.24(3) agrees with recent CLEO experiment. The values f P (1S) = 182, 216, 438 MeV are obtained for the B, B s , and B c mesons with the ratio f Bs /f B =1.19(2) and f D /f B =1.14(2). The decay constants f P (2S) for the first radial excitations as well as the decay constants f V (1S) in the vector channel are also calculated. The difference of about 20% between f Ds and f D , f Bs and f B directly follows from our analytical formulas.

“…where m is the current quark mass taken here to be equal to zero (m = 0). The potential V (r) contains in the general case both a perturbative part, the Coulomb interaction V C (r), and the nonperturbative string potential V NP (r) with a string tension that is in general dependent on the separation r [7]:…”

Light meson radial Regge trajectories

A new physical mechanism is suggested to explain the universal depletion of high meson excitations. It takes into account the appearance of holes inside the string world sheet due to qq pair creation when the length of the string exceeds the critical value R 1 Ӎ1.4 fm. It is argued that a delicate balance between large N c loop suppression and a favorable gain in the action, produced by holes, creates a new metastable ͑predecay͒ stage with a renormalized string tension which now depends on the separation r. This results in smaller values of the slope of the radial Regge trajectories, in good agreement with the analysis of experimental data of Anisovich, Anisovich, and Sarantsev.

The hyperfine splittings in heavy quarkonia are studied using new experimental data on the di-electron widths. The smearing of the spinspin interaction is taken into account, while the radius of smearing is fixed by the known J/ψ − η c (1S) and ψ(2S) − η ′ c (2S) splittings and appears to be small, r ss ≈ 0.06 fm. Nevertheless, even with such a small radius an essential suppression of the hyperfine splittings (∼ 50%) is observed in bottomonium. For the nS bb states (n = 1, 2, ...6) the values we predict (in MeV) are 28, 12, 10, 6, 6, and 3, respectively. In single-channel approximation for the 3S and 4S charmonium states the splittings 16(2) MeV and 12(4) MeV are obtained.
