Hadronic production ofWandZbosons at large transverse momentum

We introduce a modified factorization formalism in quantum chromodynamics for hadronic production of $W$ and $Z$ bosons at large transverse momentum ${p}_{T}$. When ${p}_{T}$ is much larger than the invariant mass $Q$ of the vector boson, this new factorization formalism systematically resums the large fragmentation logarithms, ${\ensuremath{\alpha}}_{s}^{m}{\mathrm{ln}}^{m}({p}_{T}^{2}/{Q}^{2})$, to all orders in the strong coupling ${\ensuremath{\alpha}}_{s}$. Using our modified factorization formalism, we present the next-to-leading-order (NLO) predictions for $W$ and $Z$ boson production at high ${p}_{T}$ at the CERN Large Hadron Collider and at a future 100 TeV proton-proton collider. Our NLO results are about 5% larger in normalization, and they show improved convergence and moderate reduction of the scale variation compared to the NLO predictions derived in a conventional fixed-order perturbative expansion.
