Combination of CDF and D0 results on the W boson mass and width Academic Article uri icon

abstract

  • The results based on 1992–95 data (Run 1) from the CDF and D0 experiments on the measurements of the [Formula Presented] boson mass and width are presented, along with the combined results. We report a Tevatron collider average [Formula Presented]. We also report the Tevatron collider average of the directly measured [Formula Presented] boson width [Formula Presented]. We describe a new joint analysis of the direct [Formula Presented] mass and width measurements. Assuming the validity of the standard model, we combine the directly measured [Formula Presented] boson width with the width extracted from the ratio of [Formula Presented] and [Formula Presented] boson leptonic partial cross sections. This combined result for the Tevatron is [Formula Presented]. Finally, we use the measurements of the direct total [Formula Presented] width and the leptonic branching ratio to extract the leptonic partial width [Formula Presented]. © 2004 The American Physical Society.
