Abstract

A study of charm fragmentation into D * and D in e e annihilations at √s=10.5 GeV is presented. This study using 4.72±0.05 fb of CLEO II data reports measurements of the cross sections σ(D * ) and σ(D ) in momentum regions above x=0.44, where x is the D momentum divided by the maximum kinematically allowed D momentum. The D vector to vector plus pseudoscalar production ratio is measured to be P (x(D )>0.44)=0.44±0.04. ©2000 The American Physical Society. s s s s s s s V s + + + - -1 + + +
