Abstract

Astronomy & Astrophysics Physical Sciences Physics Physics, Particles & Fields Science & Technology
A study of charm fragmentation into D-s(*+) and D-s(+) in e(+)e(-) annihilations at root s = 10.5 GeV is presented. This study using 4.72 +/- 0.05 fb(-1) of CLEO II data reports measurements of the cross sections sigma(D-s(*+))) and sigma(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) = 0.44 +/- 0.04.
