A measurement of the inclusive semileptonic decay fraction of charmed hadrons

Technical Report:

Abstract

Using the ARGUS detector at the DORIS-II storage ring at DESY, we have measured the inclusive semileptonic branching ratio of charmed hadrons produced in e{sup +}e{sup -} annihilation at {radical}s=10GeV to be BR(c{yields}er{sub e}X)=(9.8 {+-} 0.9 {+-} {sup 0.6} {sub 0.5})% and BR (c{yields}ur{sub u}X)=(8.6 {+-}1.7{+-}{sup 0.8}{sub 0.7})%. (orig.).
