TL;DR: The proceedings of the 2013 Les Houches workshop on physics at TeV colliders as discussed by the authors dealt primarily with the techniques for calculating standard model multi-leg NLO and NNLO QCD and NLO EW cross sections and comparison of those cross sections with LHC data from Run 1, and projections for future measurements in Run 2.

Abstract: This Report summarizes the proceedings of the 2013 Les Houches workshop on Physics at TeV Colliders. Session 1 dealt primarily with (1) the techniques for calculating standard model multi-leg NLO and NNLO QCD and NLO EW cross sections and (2) the comparison of those cross sections with LHC data from Run 1, and projections for future measurements in Run 2.

aMCfast: automation of fast NLO computations for PDF fits
TL;DR: MadGraph5 aMC@NLO as discussed by the authors is a self-contained program that calculates cross sections up to next-to-leading order accuracy in an automated manner, and APPLgrid, a code that parametrises such cross sections in the form of look-up tables which can be used for the fast computations needed in the context of PDF fits.

TL;DR: In this paper, a physically-inspired prescription for fixed-order predictions and their uncertainties is proposed, and a comparison of matched (N)NLO+LLR predictions to data from ALICE and ATLAS, finding improved consistency for the Rdependent part of the results relative to NLO predictions.
The five-loop Beta function for a general gauge group and anomalous dimensions beyond Feynman gauge
TL;DR: In this paper, a non-abelian gauge field coupled to a single representation of a family of Nf fermions is considered and the linear terms of the complete set of anomalous dimensions, in an expansion in the covariant gauge parameter around the Feynman gauge, are presented.
Pileup Mitigation with Machine Learning (PUMML)
TL;DR: In this article, a new technique for removing the contamination of the energy distribution arising from the primary collision of interest (leading vertex) by radiation from soft collisions (pileup) was developed using machine learning and convolutional neural networks.
