Query: Threshold resummation of the rapidity distribution for Drell-Yan
  production at NNLO+NNLL   We consider the production of pairs of lepton through the Drell-Yan process
at the LHC and present the most accurate prediction on their rapidity
distribution. While the fixed order prediction is already known to
next-to-next-to-leading order in perturbative QCD, the resummed contribution
coming from threshold region of phase space up to next-to-next-to-leading
logarithmic (NNLL) accuracy has been computed in this article. The formalism
developed in [1-3] has been used to resum large threshold logarithms in the two
dimensional Mellin space to all orders in perturbation theory. We have done a
detailed numerical comparison against other approaches that resum certain
threshold logarithms in Mellin-Fourier space. Our predictions at NNLL level are
close to theirs even though at leading logarithmic and next-to-leading
logarithmic level we differ. We have also investigated the impact of these
threshold logarithms on the stability of perturbation theory against
factorisation and renormalisation scales. While the dependence on these scales
does not get better with resummed results, the convergence of the perturbative
series shows a better trend compared to the fixed order predictions. This is
evident from the reduction in the K-factor for the resummed case compared to
fixed order. We also present the uncertainties on the predictions resulting
from parton distribution functions.
