Parity and CP violation in W boson decay are discussed. It is shown that CP test is possible by measuring the angular distribution in a W boson non-suppressed two-body decay mode without the polarization measurement of the final state fermions. We found that LEP200 and next linear collider (NLC) have non-trivial sensitivity on the right-handed coupling and CP violation. LEP200 will slightly improve the present limit on the right-handed coupling in the [Formula: see text] coupling, and have sensitivity on the relative magnitude of the CP violation to the P violation up to 8×10−2. NLC will improve the former by some factor or even an order of magnitude, and have sensitivity on the latter up to 10−3–10−2.

Integrated Luminosity

This review presents the world's most precise measurement of the W-boson mass mW using data corresponding to ≈ 2.2 fb-1 integrated luminosity collected with the CDF II detector at Fermi National Accelerator Laboratory (Fermilab). With samples of 470,126 W → eν candidates and 624,708 W → μν candidates, mW is measured to be 80387±12 stat ± 15 syst = 80387 ± 19 MeV [Phys. Rev. Lett.108, 151803 (2012)]. This result significantly exceeds the precision of all previous measurements and improves the world averaged precision by 30%.
