Precise predictions for boosted Higgs production
/ Becker, Kathrin (Freiburg U.) ; Caola, Fabrizio (Oxford U., Theor. Phys.) ; Massironi, Andrea (CERN ; INFN, Milan Bicocca) ; Mistlberger, Bernhard (MIT) ; Monni, Pier Francesco (CERN) ; Chen, Xuan (Zurich U.) ; Frixione, Stefano (INFN, Genoa) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Hamilton, Keith (University Coll. London) et al.
Inclusive Higgs boson production at large transverse momentum is induced by different production channels. We focus on the leading production through gluon fusion, and perform a consistent combination of the state of the art calculations obtained in the infinite-top-mass effective theory at next-to-next-to-leading order (NNLO) and in the full Standard Model (SM) at next-to-leading order (NLO).

Two-Loop QCD Corrections for Three-Photon Production at Hadron Colliders
/ Abreu, Samuel (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; De Laurentis, Giuseppe (PSI, Villigen) ; Ita, Harald (PSI, Villigen ; Zurich U.) ; Klinkert, Maximillian (Freiburg U.) ; Page, Ben (CERN) ; Sotnikov, Vasily (Zurich U. ; Michigan State U.)
We complete the computation of the two-loop helicity amplitudes for the production of three photons at hadron colliders, including all contributions beyond the leading-color approximation. We reconstruct the analytic form of the amplitudes from numerical finite-field samples obtained with the numerical unitarity method. [...]

Robust Independent Validation of Experiment and Theory: Rivet version 3
/ Bierlich, Christian (DARK Cosmology Ctr. ; Lund U.) ; Buckley, Andy (Glasgow U.) ; Butterworth, Jonathan (University Coll. London) ; Christensen, Christian Holm (Bohr Inst.) ; Corpe, Louie (Imperial Coll., London) ; Grellscheid, David (Bergen U.) ; Grosse-Oetringhaus, Jan Fiete (CERN) ; Gutschow, Christian (University Coll. London) ; Karczmarczyk, Przemyslaw (CERN ; Warsaw U.) ; Klein, Jochen (CERN ; INFN, Turin) et al.
First released in 2010, the Rivet library forms an important repository for analysis code, facilitating comparisons between measurements of the final state in particle collisions and theoretical calculations of those final states. We give an overview of Rivet's current design and implementation, its uptake for analysis preservation and physics results, and summarise recent developments including propagation of MC systematic-uncertainty weights, heavy-ion and $ep$ physics, and systems for detector emulation.

Holographic thermal correlators from supersymmetric instantons

We present an exact formula for the thermal scalar two-point function in four-dimensional holographic conformal field theories. The problem of finding it reduces to the analysis of the wave equation on the AdS-Schwarzschild background. [...]

Towards a Muon Collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

The Soft Anomalous Dimension at four loops in the Regge Limit
/ Maher, Niamh (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Falcioni, Giulio (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Gardi, Einan (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Milloy, Calum (INFN, Turin ; Turin U.) ; Vernazza, Leonardo (INFN, Turin ; CERN ; Turin U.)
The soft anomalous dimension governs the infrared divergences of scattering amplitudes in general kinematics to all orders in perturbation theory. By comparing the recent Regge-limit results for $2\to2$ scattering (through Next-to-Next-to-Leading Logarithms) in full colour to a general form for the soft anomalous dimension at four loops we derive powerful constraints on its kinematic dependence, opening the way for a bootstrap-based determination..
