The Large Hadron Collider, being a hadronic machine, has an immense potential to test the Standard Model to unprecedented accuracy and also to probe physics beyond the Standard Model. Precision studies at the Large Hadron Collider are one of the most important goals in high energy physics. In order to make the detailed comparison with the experimental results, higher order predictions from perturbative Quantum Chromodynamics play important role. We propose to undertake the task of computing higher order radiative corrections from Quantum Chromodynamics to the production of pair of vector bosons such as Zs and Ws. In particular, we will focus on the differential distributions at second order in perturbation theory. We will also systematically include threshold effects in particular for the transverse momentum distributions. This requires setting up a formalism as well as computation of various universal anomalous dimensions in perturbation theory. Our predictions will be important to understand the results at the Large Hadron Collider.
