Transverse-Momentum Resummation for Gauge Boson Pair Production at the Hadron Collider
We perform the transverse-momentum resummation for , , and
pair productions at the next-to-next-to-leading logarithmic accuracy
using soft-collinear effective theory for and
at the LHC, respectively. Especially, this is the
first calculation of transverse-momentum resummation. We also
include the non-perturbative effects and discussions on the PDF uncertainties.
Comparing with the next-to-leading logarithmic results, the
next-to-next-to-leading logarithmic resummation can reduce the dependence of
the transverse-momentum distribution on the factorization scales significantly.
Finally, we find that our numerical results are consistent with data measured
by CMS collaboration for the production, which have been only reported by
the LHC experiments for the unfolded transverse-momentum distribution of the
gauge boson pair production so far, within theoretical and experimental
uncertainties.Comment: 22 pages, 6 figures, re-versio
