The W mass measurement has been considered one of the hardest measurements in particle physics. It took the Tevatron 12 years to produce the current very impressive result of 80387 +- 16 MeV, which is expected to be a legacy of the Tevatron. The LHC experiments will naturally try to improve on this precision, but the question is if this is feasible with the high pileup at LHC. The one major advantage of the LHC is the high statistics especially of the Z-decays, and the question is now, if this statistical power can be used to harness the systematic uncertainties especially in connection with the missing transverse energy, and also control the theoretical systematic uncertainties. Some of us believe that it is possible...
