W Mass results from Tevatron and LHC

Most recent results of W boson mass measurements from Tevatron experiments (CDF and DØ) in pp¯ $par p$ collisions at √s = 1.96 GeV are reported, using 0.2 fb−1 and 1.0 fb−1 data collected at CDF and DØ, respectively. The measurements of W boson properties at LHC experiments (ATLAS, CMS, and LHCb) in pp collisions at √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.
