Two-loop amplitudes for $\mathcal{O}(\alpha_s^2)$ corrections to $W\gamma\gamma$ production at the LHC / Badger, Simon (INFN, Turin) ; Hartanto, Heribertus Bayu (APCTP, Pohang ; POSTECH) ; Wu, Zihao (HIAS, UCAS, Hangzhou) ; Zhang, Yang (Hefei, CUST ; PCFT, Hefei) ; Zoia, Simone (CERN)
We present the two-loop helicity amplitudes contributing to the next-to-next-to-leading order QCD predictions for W-boson production in association with two photons at the Large Hadron Collider. [...]

Two-loop integrals for $ t\overline{t} $+jet production at hadron colliders in the leading colour approximation / Badger, Simon (INFN, Turin) ; Becchetti, Matteo (Bologna U. ; INFN, Bologna) ; Giraudo, Nicolò (Zurich U.) ; Zoia, Simone (CERN)
We compute the differential equations for the two remaining integral topologies contributing to the leading colour two-loop amplitudes for $pp \rightarrow t\bar{t}j$. We derive differential equations for the master integrals by solving the integration-by-parts identities over finite fields. [...]

Two-loop leading-colour QCD helicity amplitudes for Higgs boson production in association with a bottom-quark pair at the LHC / Badger, Simon (INFN, Turin ; Turin U.) ; Hartanto, Heribertus Bayu (Cambridge U.) ; Kryś, Jakub (INFN, Turin ; Turin U. ; Durham U., IPPP) ; Zoia, Simone (INFN, Turin ; Turin U.)
We compute the two-loop QCD helicity amplitudes for the production of a Higgs boson in association with a bottom-quark pair at a hadron collider. We take the approximations of leading colour and work in the five flavour scheme, where the bottom quarks are massless while the Yukawa coupling is non-zero. [...]

Five jet production at next-to-leading order QCD / Badger, S D (CERN) ; Biedermann, B (Wurzburg U.) ; Uwer, P (Humboldt U., Berlin) ; Yundin, V (Munich, Max Planck Inst.)
We discuss theoretical predictions for the production of five hard jets at next-to-leading order accuracy QCD at the Large Hadron Collider. Results are shown for both the total cross section as well as for differential distributions of the jet transverse momenta and rapidities. [...]

Multi-loop integrand reduction techniques / Badger, Simon (CERN) ; Frellesvig, Hjalte (INFN, Rome ; Bohr Inst.) ; Zhang, Yang (Bohr Inst.)
We review recent progress in D-dimensional integrand reduction algorithms for two loop amplitudes and give examples of their application to non-planar maximal cuts of the five-point all-plus helicity amplitude in QCD..

Computation of multi-leg amplitudes with NJet / Badger, Simon (CERN) ; Biedermann, Benedikt (Wurzburg U.) ; Uwer, Peter (Humboldt U., Berlin) ; Yundin, Valery (Munich, Max Planck Inst.)
In these proceedings we report our progress in the development of the publicly available C++ library NJet for accurate calculations of high-multiplicity one-loop amplitudes. As a phenomenological application we present the first complete next-to-leading order (NLO) calculation of five jet cross section at hadron colliders..
