Transverse-Momentum Resummation for Gauge Boson Pair Production at the Hadron Collider

الأصل · EN

We perform the transverse-momentum resummation for W⁺W⁻, ZZ, and W±Z pair productions at the next-to-next-to-leading logarithmic accuracy using soft-collinear effective theory for √S=8 TeV and √S=14 TeV at the LHC, respectively. Especially, this is the first calculation of W±Z 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 ZZ 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.
