Extraction of the width of the W boson from measurements of [formula presented] and [formula presented] and their ratio

Journal Article

We report on measurements on inclusive cross sections times branching fractions into electrons for W and Z bosons produced in (Formula presented) collisions at (Formula presented) From an integrated luminosity of 84.5 (Formula presented) recorded in 1994–1995 using the DØ detector at the Fermilab Tevatron, we determine (Formula presented) and (Formula presented) From these, we derive (Formula presented) (Formula presented) and (Formula presented) We use the latter to set a 95% confidence level upper limit on the partial decay width of the W boson into nonstandard model final states, (Formula presented) of 0.213 GeV. Combining these results with those from the 1992–1993 data gives (Formula presented) (Formula presented) and a 95% C.L. upper limit on (Formula presented) of 0.191 GeV. Using a sample with a luminosity of 505 (Formula presented) taken at (Formula presented) we measure (Formula presented) © 2000 The American Physical Society.
