TL;DR: 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.

TL;DR: In this article, the authors present the physics reach of the HL-LHC in the realm of strong and electroweak interactions and top quark physics, and provide a glimpse of the potential of a possible further upgrade of the LHC to a 27 TeV pp collider, the High-Energy LHC (HE-LACH), assumed to accumulate an integrated luminosity of 15 ab−1.

TL;DR: In this paper, the authors show that Higgs phenomenology provides a sensitive and potentially crucial tool to constrain effective gauge interactions of sterile neutrinos, not yet probed by current experiments.

TL;DR: In this article, the authors present experimental and theoretical developments related to direct real photons since the 1970s, with a special emphasis on the recently emerged "direct photon puzzle", the simultaneous presence of large yields and strong azimuthal asymmetries of photons in heavy ion collisions, an observation that so far eluded full and coherent explanation.

TL;DR: In this paper, the NNLO corrections to isolated photon and photon-plus-jet production were described and the experimental hadron-level photon definition and isolation criteria were approximated in the theoretical parton-level calculation.

TL;DR: In this paper, an iterative cascade-based model for string dynamics is described, which is based on a cascade-fly model using string dynamics, with tunneling in a constant force field.
