Available in PDF, EPUB and Kindle. Book excerpt: The authors present a new determination of f{sub D{sub s}} using 5 million ee− c{bar c} events obtained with the CLEO II detector. Their value is derived from their new measured ratio?(D{sub s}+ →?+?)/?(D{sub s}+ →??+) = 0.173 ± 0.021 ± 0.031. Using?(D{sub s}+ →??+) = (3.6 ± 0.9)%, they extract f{sub D{sub s}} = (280 ± 17 ± 25 ± 34) MeV. They compare this result with various model calculations.
