The recent measurements by CLEO Collaboration for the inclusive J/Psi andPsi(2S) production in Upsilon(1S) decay and our previous calculation areanalyzed. The J/Psi momentum spectrum and the production ratio of Psi(2S)versus J/Psi favour Upsilon to J/Psi(Psi(2S)) + ccbar g as the dominantcontribution. We point out that the differences between the experimental dataand our previous results are mainly originated from the setting of theparameter charm quark mass. We further suggest the associate strange particleenhancement as a probe for the open charm particles in Upsilon to J/Psi(Psi(2S)) + ccbar g.Comment: minor corrections during proof-readin
