The D0 collaboration has introduced new variables (called aT and phi*) to
accurately probe the low transverse momentum region of Z boson production at
hadron colliders. I present a state-of-the-art analytical calculation of these
new variables that contains the resummation of large logarithms up to next-to
next-to leading logarithmic accuracy, matched to a full next-to leading order
calculation. Theoretical predictions are performed accounting for the
experimental cuts introduced by the D0 collaboration and it is compared to the
data.
