Description
Threshold resummation is often used to improve the theoretical accuracy of inclusive cross sections at hadron colliders. However, when differential distributions are considered, we acquire sensitivity to more energy scales which triggers the appearance of different types of logarithms. In these situations a joint resummation formalism becomes relevant. The general framework for joint threshold and $q_T$ resummation has existed for some time, but has only ever been applied at NLL accuracy. In this presentation we discuss an extension of the method for joint resummation to NNLL accuracy and apply it to Z-boson production at Tevatron and LHC as well as the heavier Z' production at LHC.
