/ Abdul Khalek, Rabah (Vrije U., Amsterdam ; Nikhef, Amsterdam) ; Forte, Stefano (INFN, Milan ; Milan U.) ; Gehrmann, Thomas (Zurich U.) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Giani, Tommaso (U.

(Nikhef, Amsterdam) ; Pires, Joao (CMAF, Lisbon) ; Rojo, Juan (Vrije U., Amsterdam ; Nikhef, Amsterdam) et al.
We present a systematic investigation of jet production at hadron colliders from a phenomenological point of view, with the dual aim of providing a validation of theoretical calculations and guidance to future determinations of parton distributions (PDFs). We account for all available inclusive jet and dijet production measurements from ATLAS and CMS at 7 and 8 TeV by including them in a global PDF determination, and comparing to theoretical predictions at NNLO QCD supplemented by electroweak (EW) corrections.

The transverse momentum spectrum of weak gauge bosons at N$^3$LL$+$NNLO

(Durham U., IPPP)
We present accurate QCD predictions for the transverse momentum pT spectrum of electroweak gauge bosons at the LHC for 13 TeV collisions, based on a consistent combination of a NNLO calculation at large pT and N3LL resummation in the small pT limit. The inclusion of higher order corrections leads to substantial changes in the shape of the differential distributions, and the residual perturbative uncertainties are reduced to the few percent level across the whole transverse momentum spectrum.

Jet cross sections at the LHC and the quest for higher precision
/ Bellm, Johannes (Lund U.) ; Buckley, Andy (Glasgow U.) ; Chen, Xuan (Zurich U.) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Pires, Joao (Lisbon, CFTP) ; Höche, Stefan (SLAC ; Fermilab) ; Huston, Joey (Michigan State U.) et al.
We perform a phenomenological study of $Z$ plus jet, Higgs plus jet and di-jet production at the Large Hadron Collider. We investigate in particular the dependence of the leading jet cross section on the jet radius as a function of the jet transverse momentum. [...]

NNLO predictions for jets and V+jet at the LHC
/ Huss, Alexander Yohei (CERN) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Thomas, Gehrmann (Zurich U.) ; Nigel, Glover (Durham U.) ; James, Currie (Durham U.) ; Duncan, Walker (Durham U.) ; Joao, Pires (Lisbon, CFTP)
The production of jets and electroweak gauge bosons in association with a jet, V+jet, constitute two important classes of standard-candle processes at the LHC. Owing to the large event rate and the direct sensitivity to the strong coupling constant and the gluon PDF, they provide an ideal testing ground for our understanding of perturbative QCD in a hadron-collider environment.

NNLO QCD Corrections to W+jet Production in NNLOJET
/ Gehrmann-De Ridder, Aude (Zurich, ETH ; Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander Yohei (CERN) ; Walker, Duncan (Durham U., IPPP)
We give an overview of our calculation of the next-to-next-to-leading order (NNLO) QCD corrections to W + jet production in hadronic collisions. Phenomenological results for multiple differential distributions are compared to CMS data for 8 TeV proton-proton collisions. [...]

Jet cross sections at the LHC with NNLOJET

We review the status of NNLO calculations for jet cross sections at the LHC. In particular, we describe how perturbative stability and convergence can be used as criteria to select the most appropriate scales in the theoretical description of di-jet and single jet inclusive production..

Infrared sensitivity of single jet inclusive production at hadron colliders
/ Currie, James (Durham U., IPPP) ; Gehrmann-De Ridder, Aude (ETH, Zurich (main) ; Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, E.W. Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Pires, João (Lisbon, CFTP)
Jet production at hadron colliders is a benchmark process to probe the dynamics of the strong interaction and the structure of the colliding hadrons. One of the most basic jet production observables is the single jet inclusive cross section, which is obtained by summing all jets that are observed in an event. [...]

Fiducial distributions in Higgs and Drell-Yan production at N$^3$LL+NNLO
/ Bizoń, Wojciech (Oxford U., Theor. Phys.) ; Chen, Xuan (Zurich U.) ; Gehrmann-De Ridder, Aude (Zurich U. ; Zurich, ETH) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (CERN ; Annecy, LAPTH) ; Rottoli, Luca (Oxford U., Theor. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin)
The perturbative description of certain differential distributions across a wide kinematic range requires the matching of fixed-order perturbation theory with resummation of large logarithmic corrections to all orders. We present precise matched predictions for transverse-momentum distributions in Higgs boson (H) and Drell-Yan pair (DY) production as well as for the closely related ${\phi^{*}_\eta}$ distribution at the LHC.
