Coulomb effects in the decays $Υ(4S) \rightarrow B\bar B$

Abstract:A simple exactly solvable model is proposed for describing the decays Υ(4S) → B 0 B0 and Υ(4S) → B + B − . Our predictions agree with available experimental data. Using this model, we analyze the Coulomb effects in the spectra of these decays. It is shown that the frequently used assumption of factorization of Coulomb effects is not fulfilled. The Coulomb interaction leads to the difference in the positions and heights of the peaks corresponding to the charged and neutral modes. As a result, the ratio of proba… Show more
