We give an introduction to several regularization schemes that deal with ultraviolet and
infrared singularities appearing in higher-order computations in quantum field theories …

The successful operation of the Large Hadron Collider (LHC) and the excellent performance
of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $ pp $ collisions at …

This Report summarizes the proceedings of the 2019 Les Houches workshop on Physics at
TeV Colliders. Session 1 dealt with (I) new developments for high precision Standard Model …

A bstract Several problems in computer algebra can be efficiently solved by reducing them
to calculations over finite fields. In this paper, we describe an algorithm for the reconstruction …

A bstract We compute the NNLO QCD corrections to three-photon production at the LHC.
This is the first NNLO QCD calculation for a 2→ 3 process. Our calculation is exact, except …

A bstract We present an analytic computation of the gluon-initiated contribution to diphoton
plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic …

We present the analytic form of all leading-color two-loop five-parton helicity amplitudes in
QCD. The results are analytically reconstructed from exact numerical evaluations over finite …

Loop amplitudes are conveniently expressed in terms of master integrals whose coefficients
carry the process dependent information. Similarly before integration, the loop integrands …

This report comprises the outcome of five working groups that have studied the physics
potential of the highluminosity phase of the LHC (HL-LHC) and the perspectives for a …
