W Mass results from Tevatron and LHC

TL;DR

This paper reviews recent $W$ boson mass measurements from Tevatron and LHC experiments, highlighting their methods, challenges, and future prospects for precision in high-energy physics.

Contribution

It provides a comprehensive comparison of $W$ mass measurements at Tevatron and LHC, including challenges and future outlook, which is novel in synthesizing these results.

Findings

Tevatron achieved $W$ mass measurements with 0.2 and 1.0 fb^{-1} data.

LHC experiments collected data at 7 TeV before Summer 2011 for $W$ properties.

Challenges at LHC differ from Tevatron, affecting $W$ mass measurement precision.

Abstract

Most recent results of $W$ boson mass measurements from Tevatron experiments (CDF and D0) in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ GeV are reported, using $0.2 fb^{-1}$ and $1.0 fb^{-1}$ data collected at CDF and D0, respectively. The measurements of $W$ boson properties at LHC experiments (ATLAS, CMS, and LHCb) in $pp$ collisions at $\sqrt{s}=7$ TeV, using data collected before Summer 2011, are presented. These measurements are essential at the preparation stage of the $W$ boson mass measurements at LHC. Challenges for $W$ mass measurement at the LHC in comparison with the Tevatron are outlined. Prospects for $W$ mass precision with upcoming measurements and its implications are discussed.
