Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The success of the experimental program at the Tevatron re-inforced the idea that precision
physics at hadron colliders is desirable and, indeed, possible. The Tevatron data strongly …

The production of a top-antitop quark pair in association with a W boson (tt¯ W) is one of the
heaviest signatures currently probed at the Large Hadron Collider. Since the first …

A bstract We discuss the theoretical bases that underpin the automation of the computations
of tree-level and next-to-leading order cross sections, of their matching to parton shower …

A bstract We present a general method that allows one to decay narrow resonances in Les
Houches Monte Carlo events in an efficient and accurate way. The procedure preserves …

A bstract We present results for the production of a top pair in association with a W-boson at
next-to-leading order. We have implemented this process into the parton-level integrator …

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 We present a fully automated implementation of next-to-leading order electroweak
(NLO EW) corrections in the O pen L oops matrix-element generator combined with the …

We present the program package GoSam which is designed for the automated calculation of
one-loop amplitudes for multi-particle processes in renormalisable quantum field theories …

The AcerMC Monte Carlo generator is dedicated to the generation of Standard Model
background processes which were recognised as critical for the searches at LHC, and …
