The shift of the p-wave D s meson mass due to coupling to the DK channel is calculated using a QCD string model and the chiral Lagrangian. As a result the original Q q mass, 2.490 MeV, generically calculated in the relativistic quark models is shifted down to the experimental value 2317 MeV. With the same Lagrangian the shift of the radial excited 1 ÿ level is much smaller, while the total width ÿ > 100 MeV and the width ratio is in contradiction with the D 2632 state observed by SELEX Collaboration.

Two-and three-body decays of Υ(5S) into BB,BB * , B * B * , B s B s , B s B * s , B * s B * s and BB * π, B * B * π are evaluated using the theory, developed earlier for dipion bottomonium transitions. The theory contains only two parameters, vertex masses M br and M ω , known from dipion spectra and width. Predicted values of Γ tot (5S) and six partial widths Γ k (5S), k = BB, BB * , ... are in agreement with experiment. The decay widths Γ 5S (πBB * ) and Γ 5S (πB * B * ) are also calculated and found to be of the order of 10 keV.
