Description
The Drell Yan process serves as standard candle in order to identify beyond Standard Model signatures. In this talk, we plan to focus on the virtual correction to the Z-production at the order $\mathcal{O}(\alpha_s^2\alpha)$, which constitute a subset of the factorizable electroweak-QCD corrections to Drell-Yan at resonance. Our results are complete analytic, which offers advantages in multiple ways. The introduction of one electroweak gauge boson complicates the situation in many ways, from the rapid growth of the number of MIs, their evaluation to the very large analytic expression and their simplification and renormalization. Furthermore, the singlet contribution introduces different types of trace orderings, which needs very careful treatment. The talk aims to discuss the evaluation of the form-factors along with the required renormalization. Lastly we discuss the phenomenological implication of the results and outline future directions.
