Title: Electroweak Precision Measurements at Hadron Colliders

Abstract: The electroweak precision measurement is amoung the most
important topics in experimental physics. In the past decades, many
milestones in particle physics, including the discovery of the W and Z
bosons, the top quark and the Higgs boson, benifit from the electroweak
precision measurement and corresponding global fitting. From the
beginning of this century, electroweak precision measurement has been
performed at hadron colliders. After the discovery of the top quark and
Higgs boson, it becomes important to help searching the beyond standard
model phenomenon (especially for the situation that we did not have
clear clue for new physics by direct searching at the LHC). To provide
high precision for fundamental parameters in the electroweak theory (the
W boson mass and the effective weak mixing angle), multiple topics have
to be studied., including one order of magnitude improvement on the
lepton reconstruction, better modelling of the PDF and calculation in
QCD, and study on the strategy of performing such measurements at high
instantaneous luminosity colliders. The reporter will discuss the
highlights in the electroweak precision measurement at the Fermilab’s
Tevatron, and introduce the current status of measurements at the CERN LHC.
