TL;DR
This paper reports a precise measurement of the W-boson mass using data from the ALEPH detector at LEP, combining new data with previous results to improve accuracy.
Contribution
It presents a new combined measurement of the W-boson mass incorporating 1998 data with earlier results, enhancing the precision of this fundamental parameter.
Findings
W-boson mass measured as 80.411 GeV/c2
Total uncertainty reduced through data combination
Results consistent with Standard Model predictions
Abstract
The W-boson mass has been measured using the ALEPH detector at LEP. Preliminary results from data taken in 1998 are added to previous measurements to give mW = 80.411 +- 0.064(stat.) +- 0.037(syst.) +- 0.022(BE-CR) +- 0.018(LEP) GeV/c2.
