Parton distributions in the SMEFT from high-energy Drell-Yan tails

We thank Emanuele Mereghetti, Tevong You and Celine Degrande for insightful discussions about the project. We thank Claude Duhr and Bernhard Mistlberger for kindly sending us the NNLO and N3LO QCD corrections for the Drell-Yan invariant and transverse mass distributions. We thank Andrea Wulzer and Lorenzo Ricci for benchmarking the charged current K-factors and for suggesting to add the results obtained by using conservative PDFs. M. U. and Z.
