Measurement Of Angular Coefficients Of Drell-Yan E(+) E(-) Pairs In Ppbar Collisions At Square Root Of Center Of Mass Energy Of 1.96 Tev.
… we present the status of the measurement of angular distributions of final state electrons in ppbar → γ*/Z → e+ e− + X events produced in the Z boson mass region at square root of center of mass energy of 1.96 TeV at the Tevatron. For this analysis, we have used the Run IIb2 dataset collected …

Measurement of the Differential Angular Distribution of the W Boson Produced in Association With Jets in Proton -Antiproton Collisions at Center of Mass Energy = 1.8 TeV
… present the Standard Model prediction for the W angular coefficients Ai as a function of pWT , using a W+jet Monte Carlo event generator, which includes gluon loops. The prediction for three of the angular coefficients (A1, A4 and A6) is presented for the first time.

Measurement of the differential angular distribution of the W boson produced in association with jets in proton-antiproton collisions at sqrt (s)= 1.8 TeV
… unpolarized cross section we end up with eight angular coefficients (A0 - A7), which describe theW decay distribution. At low W transverse momentum, only one of the angular coefficients is non-zero. In order to study all the coefficients, we need to study the production of the W at high …

Precision Physics with W-bosons at the Large Hadron Collider
… how polarisation quantities, in particular, angular coefficients, are instrumental in precise W-boson mass measurements which aim to reach 0.01% level of precision. Aiming to fill the gap for precise theoretical input, we provide NNLO + NLO EW predictions, and comment on their effects and …
