Description
We investigate the transverse momentum dependence of the angular distribution in the Drell-Yan process, incorporating $\gamma/Z^0$ interference in the dilepton decay. Our partonic-level analytical calculations are performed in perturbative QCD using collinear factorization at order $\alpha_s$. We analytically calculate the partonic-level T-even helicity structure functions and subsequently convolve them numerically with parton distribution functions to obtain hadronic-level observables, including angular coefficients and the forward-backward asymmetry.
