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. [...]

Isolated photon and photon+jet production at NNLO QCD accuracy
/ Chen, Xuan (Zurich U.) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Höfer, Marius (Zurich U.) ; Huss, Alexander (CERN)
We describe the calculation of the next-to-next-to-leading order (NNLO) QCD corrections to isolated photon and photon-plus-jet production, and discuss how the experimental hadron-level photon definition and isolation criteria can be approximated in the theoretical parton-level calculation. The NNLO corrections lead to a considerable reduction of the theory uncertainty on the predictions, typically to less than five per cent, and enable an improved description of experimental measurements from ATLAS and CMS..

Top-quark mass effects in $H$+jet and $H$+2 jets production
/ Chen, X. (KIT, Karlsruhe ; KIT, Karlsruhe, TP ; Zurich U.) ; Huss, A. (CERN) ; Jones, S.P. (Durham U., IPPP) ; Kerner, M. (KIT, Karlsruhe ; KIT, Karlsruhe, TP ; Zurich U.) ; Lang, J.-N. (Zurich U.) ; Lindert, J.M. (Sussex U.) ; Zhang, Hantian (Zurich U. ; KIT, Karlsruhe, TTP)
We present calculations of Higgs boson production via gluon-gluon fusion in association with one or two additional jets at next-to-leading order in QCD. The calculation of H+jet is exact in the treatment of the top-quark mass, whereas for the $H+$2 jets calculation the two-loop virtual amplitudes are approximated via a reweighting with leading-order mass effects, while keeping all top-quark mass effects in the real radiation contributions.

A comparative study of Higgs boson production from vector-boson fusion
/ Buckley, A. (Glasgow U.) ; Chen, X. (Zurich U. ; KIT, Karlsruhe, TP ; KIT, Karlsruhe, SCC) ; Cruz-Martinez, J. (INFN, Milan ; Milan U.) ; Ferrario Ravasio, S. (Oxford U., Ctr.

(Sussex U.) et al.
The data taken in Run II at the LHC have started to probe Higgs boson production at high transverse momentum. Future data will provide a large sample of events with boosted Higgs boson topologies, allowing for a detailed understanding of electroweak Higgs boson plus two-jet production, and in particular the vector-boson fusion mode (VBF).

NNLO QCD predictions for Z-boson production in association with a charm jet within the LHCb fiducial region
/ Gauld, R. (Munich, Max Planck Inst.) ; Gehrmann-De Ridder, A. (ETH, Zurich (main) ; Zurich U.) ; Glover, E.W. N. (Durham U., IPPP ; Durham U.) ; Huss, A. (CERN) ; Garcia, A. Rodriguez (ETH, Zurich (main)) ; Stagnitto, G. (Zurich U.)
We compute next-to-next-to-leading order (NNLO) QCD corrections to neutral vector boson production in association with a charm jet at the LHC. This process is studied in the forward kinematics at $\sqrt{s}=13$ TeV, which may provide valuable constraints on the intrinsic charm component of the proton. [...]

NNLO interpolation grids for jet production at the LHC
/ Britzger, D. (Munich, Max Planck Inst.) ; Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Gehrmann, T. (Zurich U.) ; Glover, E.W. N. (Durham U., IPPP) ; Gwenlan, C. (Oxford U.) ; Huss, A. (CERN) ; Pires, J. (LIP, Lisbon ; Lisbon U.) ; Rabbertz, K. (KIT, Karlsruhe, ETP ; CERN) ; Savoiu, D. (Hamburg U.) ; Sutton, M.R. (Sussex U.) et al.
Fast interpolation-grid frameworks facilitate an efficient and flexible evaluation of higher-order predictions for any choice of parton distribution functions or value of the strong coupling $\alpha_s$. They constitute an essential tool for the extraction of parton distribution functions and Standard Model parameters, as well as studies of the dependence of cross sections on the renormalisation and factorisation scales.

Single Photon Production at Hadron Colliders at NNLO QCD with Realistic Photon Isolation
/ Chen, X. (KIT, Karlsruhe, TP ; KIT, Karlsruhe, IAP) ; Gehrmann, T. (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP) ; Höfer, M. (Munich U., ASC) ; Huss, A. (CERN) ; Schürmann, R. (Zurich U.)
Isolated photons at hadron colliders are defined by permitting only a limited amount of hadronic energy inside a fixed-size cone around the candidate photon direction. This isolation criterion admits contributions from collinear photon radiation off QCD partons and from parton-to-photon fragmentation processes. [...]
