PDF4LHC recommendations for LHC Run II
read the original abstract
We provide an updated recommendation for the usage of sets of parton distribution functions (PDFs) and the assessment of PDF and PDF+$\alpha_s$ uncertainties suitable for applications at the LHC Run II. We review developments since the previous PDF4LHC recommendation, and discuss and compare the new generation of PDFs, which include substantial information from experimental data from the Run I of the LHC. We then propose a new prescription for the combination of a suitable subset of the available PDF sets, which is presented in terms of a single combined PDF set. We finally discuss tools which allow for the delivery of this combined set in terms of optimized sets of Hessian eigenvectors or Monte Carlo replicas, and their usage, and provide some examples of their application to LHC phenomenology.

Effective field theory interpretation of ATLAS measurements involving the Higgs boson, electroweak bosons and the top quark
A simultaneous fit to multiple ATLAS datasets constrains 48 SMEFT Wilson coefficients and matches subsets to 2HDM and heavy-vector models, finding consistency with the Standard Model.
