InclusiveχbJ(nP)decays toD0X

Using {upsilon}(2S) and {upsilon}(3S) data collected with the CLEO III detector we have searched for decays of {chi}{sub bJ} to final states with open charm. We fully reconstruct D{sup 0} mesons with p{sub D{sup 0}}>2.5 GeV/c in three decay modes (K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup 0}, and K{sup -}{pi}{sup -}{pi}{sup +}{pi}{sup +}) in coincidence with radiative transition photons that tag the production of one of the {chi}{sub bJ}(nP) states. Significant signals are obtained for the two J=1 states. Recent nonrelativistic QCD (NRQCD) calculations of {chi}{sub bJ}(nP){yields}ccX depend on one nonperturbative parameter per {chi}{sub bJ} triplet. The extrapolation from the observed D{sup 0}X rate over a limited momentum range to a full ccX rate also depends on these same parameters. Using our data to fit for these parameters, we extract results which agree well with NRQCD predictions, confirming the expectation that charm production is largest for the J=1 states. In particular, for J=1, our results are consistent with ccg accounting for about one-quarter of all hadronic decays.
