The proceedings of the 2019 Les Houches workshop on physics at TeV colliders as discussed by the authors dealt with new developments for high precision Standard Model calculations, the sensitivity of parton distribution functions to the experimental inputs, new developments in jet substructure techniques and a detailed examination of gluon fragmentation at the LHC, issues in the theoretical description of the production of Standard Model Higgs bosons and how to relate experimental measurements.Abstract:
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 calculations, (II) the sensitivity of parton distribution functions to the experimental inputs, (III) new developments in jet substructure techniques and a detailed examination of gluon fragmentation at the LHC, (IV) issues in the theoretical description of the production of Standard Model Higgs bosons and how to relate experimental measurements, and (V) Monte Carlo event generator studies relating to PDF evolution and comparisons of important processes at the LHC.read more

The automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations
Johan Alwall,Rikkert Frederix,Stefano Frixione,Valentin Hirschi,Fabio Maltoni,Olivier Mattelaer,Hua-Sheng Shao,Tim Stelzer,Paolo Torrielli,Marco Zaro,Marco Zaro +10 more
TL;DR: MadGraph5 aMC@NLO as discussed by the authors is a computer program capable of handling all these computations, including parton-level fixed order, shower-matched, merged, in a unified framework whose defining features are flexibility, high level of parallelisation and human intervention limited to input physics quantities.
Journal ArticleDOI
The anti-$k_t$ jet clustering algorithm
TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.
