Electroweak corrections to the angular coefficients in finite-$p_T$ $Z$-boson production and dilepton decay

Understand

We present next-to-leading order (NLO) electroweak corrections to the dominant five angular coefficients parametrizing the Drell-Yan process in the $Z$-boson mass peak range for finite-$p_T$ vector boson production.

• The results are presented differentially in the vector boson transverse momentum.
• The Lam-Tung violating difference $A_0-A_2$ is examined alongside the coefficients.
• A single lepton transverse momentum cut is needed in the case of electroweak corrections to avoid a double singularity in the photon induced diagrams, and the dependence on the value of this cut is examined.
