Strong decays and dipion transitions of Γ(5S)

Dipion transitions of gamma(nS) with n = 5, n' = 1, 2, 3 are studied using the Field Correlator Method, applied previously to dipion transitions with it = 2, 3, 4, The only two parameters of effective Lagrangian were fixed in that earlier Study, and total widths Gamma(pi pi) (5,n') as well as pionless decay widths Gamma(B B)(5S), Gamma(B) (B*) (5S), Gamma(B* B*) (5S) and Gamma(K K) (5, n') were calculated and are in a reasonable agreement with experiment. The experimental pi pi spectra for (5, 1) and (5, 2) transitions are well reproduced taking into account FSI in the pi pi. (C) 2008 Elsevier B.V. All rights reserved.
