Next-to-leading-order QCD Corrections to Higgs Production in association with a Jet
/ Bonciani, Roberto (Rome U.) ; Del Duca, Vittorio (INFN, Rome ; Zurich U. ; Frascati) ; Frellesvig, Hjalte (Bohr Inst.) ; Hidding, Martijn (Uppsala U.) ; Hirschi, Valentin (CERN) ; Moriello, Francesco (Unlisted, CH) ; Salvatori, Giulio (Princeton, Inst. Advanced Study) ; Somogyi, Gábor (Wigner RCP, Budapest) ; Tramontano, Francesco (Naples U. ; INFN, Naples)
We compute the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC, with exact dependence on the mass of the quark circulating in the heavy-quark loops. The NLO corrections are presented including the top-quark mass, and for the first time, the bottom-quark mass as well. [...]

Higgs boson cross sections for the high-energy and high-luminosity LHC: cross-section predictions and theoretical uncertainty projections
/ Calderon Tazon, Alicia (Universidad de Cantabria and CSIC (ES)) ; Caola, Fabrizio (University of Durham (GB)) ; Campbell, John (Fermilab (US)) ; Francavilla, Paolo (Universita & INFN Pisa (IT)) ; Marchiori, Giovanni (Centre National de la Recherche Scientifique (FR)) ; Becker, Kathrin (Albert Ludwigs Universitaet Freiburg (DE)) ; Bertella, Claudia (Chinese Academy of Sciences (CN)) ; Bonvini, Marco (Sapienza Universita e INFN, Roma I (IT)) ; Chen, Xuan (Zuerich University (CH)) ; Frederix, Rikkert (Technische Universität Muenchen (DE)) et al.
This note summarizes the state-of-the-art predictions for the cross sections expected for Higgs boson production in the 27 TeV proton-proton collisions of a high-energy LHC, including a full theoretical uncertainty analysis. It also provides projections for the progress that may be expected on the timescale of the high-luminosity LHC and an assessment of the main limiting factors to further reduction of the remaining theoretical uncertainties..

Constraining anomalous gluon self-interactions at the LHC: a reappraisal
/ Hirschi, Valentin (Zurich, ETH) ; Maltoni, Fabio (Louvain U., CP3) ; Tsinikos, Ioannis (Louvain U., CP3 ; Munich, Tech. U.) ; Vryonidou, Eleni (CERN)
Anomalous self-interactions of non-abelian gauge fields can be described by higher dimensional operators featuring gauge-invariant combinations of the field strengths. In the case of QCD, the gluon self-interactions start to be modified at dimension six by operators of the type $GGG$, with $G$ the gluon field strength tensor, possibly leading to deviations in all observables and measurements that probe strong interactions at very small distances. [...]

The complete NLO corrections to dijet hadroproduction
/ Frederix, Rikkert (Munich, Tech. U.) ; Frixione, Stefano (INFN, Genoa) ; Hirschi, Valentin (SLAC) ; Pagani, Davide (Munich, Tech. U. ; Louvain U., CP3) ; Shao, Hua-Sheng (CERN) ; Zaro, Marco (UPMC, Paris (main) ; Paris, LPTHE)
We study the production of jets in hadronic collisions, by computing all contributions proportional to $\alpha_S^n\alpha^m$, with $n+m=2$ and $n+m=3$. These correspond to leading and next-to-leading order results, respectively, for single-inclusive and dijet observables in a perturbative expansion that includes both QCD and electroweak effects.

NLO predictions for the production of a spin-two particle at the LHC
/ Das, Goutam (Saha Inst.) ; Degrande, Celine (Durham U., IPPP) ; Hirschi, Valentin (SLAC) ; Maltoni, Fabio (Louvain U., CP3) ; Shao, Hua-Sheng (CERN)
We obtain predictions accurate at the next-to-leading order in QCD for the production of a generic spin-two particle in the most relevant channels at the LHC: production in association with coloured particles (inclusive, one jet, two jets and $t\bar t$), with vector bosons ($Z,W^\pm,\gamma$) and with the Higgs boson. We present total and differential cross sections as well as branching ratios as a function of the mass and the collision energy also considering the case of non-universal couplings to standard model particles.
