Jet cross sections at the LHC with NNLOJET
/ Currie, James (Durham U., IPPP) ; Gehrmann-De Ridder, Aude (Zurich, ETH ; Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Pires, Joao (Lisbon, CFTP)
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..

This talk discusses recent results for next-to-next-to-leading order (NNLO) QCD corrections to jet cross sections and transverse momentum distributions. The results are obtained in the NNLOJET code framework, which provides an implementation of the antenna subtraction method for the handling of infrared singular contributions at NNLO. [...]

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. [...]

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. [...]

Associated production of a Higgs boson decaying into bottom quarks and a weak vector boson decaying leptonically at NNLO in QCD
/ Gauld, R. (Nikhef, Amsterdam) ; Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Huss, A. (CERN) ; Majer, I. (Zurich, ETH)
We present the calculation of next-to-next-to-leading order (NNLO) corrections in perturbative QCD for the production of a Higgs boson decaying into a pair of bottom quarks in association with a leptonically decaying weak vector boson: $\mathrm{pp} \to V \mathrm{H} + X \to \ell\bar{\ell}\;\mathrm{b\bar{b}} + X$. We consider the corrections to both the production and decay sub-processes, retaining a fully differential description of the final state including off-shell propagators of the Higgs and vector boson.

The triple differential di-jet cross section at the LHC
/ Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U.) ; Huss, A. (CERN) ; Pires, J. (Lisbon, CFTP ; LIP, Lisbon)
The measurement of the triple-differential dijet production cross section as a function of the average transverse momentum $p_{T,\textrm{avg}}$, half the rapidity separation $y^{*}$, and the boost $y_{b}$ of the two leading jets in the event enables a kinematical scan of the underlying parton momentum distributions. We compute for the first time the second-order perturbative QCD corrections to this triple-differential dijet cross section, at leading color in all partonic channels, thereby enabling precision studies with LHC dijet data.

Calculations for deep inelastic scattering using fast interpolation grid techniques at NNLO in QCD and the extraction of $\alpha_s$ from HERA data

The extension of interpolation-grid frameworks for perturbative QCD calculations at next-to-next-to-leading order (NNLO) is presented for deep inelastic scattering (DIS) processes. A fast and flexible evaluation of higher-order predictions for any a posteriori choice of parton distribution functions (PDFs) or value of the strong coupling constant is essential in iterative fitting procedures to extract PDFs and Standard Model parameters as well as for a detailed study of the scale dependence.

NNLO QCD Corrections for Higgs-plus-jet Production in the Four-lepton Decay Mode
/ Chen, Xuan (Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U.) ; Huss, Alexander (CERN)
We present the computation of Higgs boson production in association with a jet at the LHC including QCD corrections up to NNLO. The calculation includes the subsequent decay of the Higgs boson into four leptons, allowing for the full reconstruction of the final-state kinematics. [...]

Vector Boson Production in Association with a Jet at Forward Rapidities
/ Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Huss, A. (CERN) ; Walker, D.M. (Durham U., IPPP)
Final states with a vector boson and a hadronic jet allow one to infer the Born-level kinematics of the underlying hard scattering process, thereby probing the partonic structure of the colliding protons. At forward rapidities, the parton collisions are highly asymmetric and resolve the parton distributions at very large or very small momentum fractions, where they are less well constrained by other processes.

Jet cross sections at the LHC and the quest for higher precision

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. [...]
