Measurements of charm fragmentation into D <inf>s</inf> * + and D <inf>s</inf>+ in e + e - annihilations at s=10.5 GeV

A study of charm fragmentation into D s * + and D s+ in e + e - annihilations at s=10.5 GeV is presented. This study using 4.720.05 fb -1 of CLEO II data reports measurements of the cross sections (D s * + ) and (D s+ ) in momentum regions above x=0.44, where x is the D s momentum divided by the maximum kinematically allowed D s momentum. The D s vector to vector plus pseudoscalar production ratio is measured to be P V (x(D s+ )>0.44)=0.440.04. 2000 The American Physical Society.
