Abstract

Analyzing Y(nS) decays acquired with the CLEO detector operating at the CESR e+e- collider, we measure for the first time the product branching fractions B[Y(nS)→YX bJ((n-1)P)]B[X bJ(n-1)P)→Xi] for n=2 and 3, where Xi denotes, for each i, one of the 14 exclusive light-hadron final states for which we observe significant signals in both X bJ(1P) and X bJ(2P) decays. We also determine upper limits for the electric dipole (E1) transitions Y(3S)→YX bJ(1P).
